vol.17 FXAA.. as in Battlefield 3 ..

[Independentsoul]

After a long progress I finaly have come to an acceptable end.
I made a Realtime Bokeh Depth of Field Auto Focus Post process wich is based on the iris of ur eye .Pretty straightforward calculations wich came together from various papers. I hope u like it .

[Dr Bearhands]

This looks realy cool!
How is the focus depth/distance being set btw? A trace from the centre of the screen?
It looks a little bit overdone btw, is the defocus ammount easilly changed?

[Drevlin]

It does look really cool, but just looking at those shots makes me really dizzy. :)
I understand you have exadurated the effect but it would be cool to see it applied in a simillar fashion to how it would actually be used in games.

[CoffeeGrunt]

I think it adds a touch of realism, although if used more sparingly...

Are you selling this shader?

[shahafyz57]

this is really cool does it have a minimum distance in order to be focused on something or any distance?
and is there a limit to object size in order for the focus to work?

[unreal_polyneutron]

It's a new step to photorealism! As for me, I found these pics with so good DOF effect just like I see everyday from my eyes. Awesome work!

[CoffeeBob]

Very nice shader! The effect is awesome, looks very realistic. It looks like it's quite heavy on the hardware though. How's the impact on the framerate while using it?

[Independentsoul]

thnx guys
Dr. Bearhands : its focus was calcualted by an average pixel calculation
shahafyz57: its based on zdepth . the good thing is that udk supports alpha/translucent Zdepth so Its focus isnt dependent to the size just the distance its very acurate

those shaders arent heavy.. I just have an fps hit from 15 fps quite a low cost for such a "realistic look"

I think about Selling . but they are still wip

there is a question How can I acces the rtt function in shaders means rendering the shader to a texture and then downsize/downsample it for a Heavy Blur.

[Dr Bearhands]

those shaders arent heavy.. I just have an fps hit from 15 fps quite a low cost for such a "realistic look"

So what is the percentual hit exactly?
Btw if you want to improve it you may want to set the depth depending on a variable settable through script, that way you can do the trace thingy (focus in centre is slightly more realistic) and other things like smooth transition (or dare I say eye tracking).

[Independentsoul]

I didnt made this shader for such stuff its a standard focus (next step is slow adaption)

"I optimized the shader today"

"there is a question How can I acces the rtt function in shaders means rendering the shader to a texture and then downsize/downsample it for a Heavy Blur. "

here two screenshots u can see the fps on the right top side

It looks overdone because I wanted to show the effect..

[Independentsoul]

JamieG I'll do it from now on

[danimal']

Great work! As suggested, I'd really like to see it used very, very lightly in a video, more appropriate for a game. Keep the overdone ones to show off the effect, but make a video with a more realistic amount of DoF? Regardless, very, very cool!

[Independentsoul]

Im working now on a an advanced Screen Space Color Bleeding Post process

Does anyone know where I can get the Luminance texture from the udk source? because tex2D(LightAttenuationTexture,ScreenUV) outputs a float3 (0,0,0);

[Independentsoul]

Danimal:

I just have those levels wich were made by the UDK devs maybe u have some nice looking levels where I could show my Post Processing .. thnx

what do u mean by "more realistic amount of DoF"? It is based on physical calculated numbers/floats. I guess u mean slightly ... instead of lightly

[Dr Bearhands]

Actually I kind of like the ammount in the last screenshot (in conjunction with the scene), but I agree it would be cool to see it in a vid.

[Independentsoul]

acutally I made a vid.. look at the first post .. http://www.youtube.com/watch?v=eR2-8xmf09I

my bad then. Looks good! It could use a little interpolation I think though. It seems sometimes it's bit too sudden and the effect is a bit annoying.

[Independentsoul]

interpolating causes higher instructions and a bloom kind of effect.. and its not physical based

Any info on a release for this? You've done an exceptional job, and I think a lot of people would find value in this. You could even charge a reasonable amount for it, I'm sure.

A lot of us are simply artists and not real programmers, and use the UDK to show off our modeling and texturing skills. Something like this would really be an asset for those who are like me and could use that extra graphical "bump."

Does your tonemapping post process interpolate between low and high exposure?

[Independentsoul]

due the Slow adaption average luminance calculation problem,wich I can´t solve , not yet .But I´m on the way

[TheDopefish]

Thanks for the screenshots of your bleach bypass effect, looks lovely!
I really like your work on the tonemapping aswell, but it seems like some areas becomes overly bright, and you loose alot of details from the scene because of it. Wouldn't it be possible to have some kind of clamp or max threshold to avoid the luminance levels going too far?

[Independentsoul]

Hi Dopefish nice to meet you here.
thnx,I already did it but I wanted to show the effect on high exposure.. cause it adds a blue tint on it kinda like it .. I have aswell settle settings. It´s just a matter of how you set up Reinhards Tonemapper :)

[CoffeeGrunt]

Ouch, this looks beautiful, but my system can't even run the stock maps as is - nevermind with this love dripping off the screen...

I implented the newest 3d glasses technique wich was used by batman arkaham asyulm (game of the year)... the company who made is called Trioviz..

3 level 3d technique based on depth http://www.trioviz.com/

* FORCE 1: provide the best color perception with subtile and pleasant 3-D experience.

* FORCE 2: provide a perfect compromise between colors and 3-D experience.

* FORCE 3: provide the best 3-D experience with soft satured and natural colors.

I mean it doesn't seem like this is for your portfolio so what is your motive/objective for all of this in 85 post. cuz it just seems like your hyping up ppl for something.

Are you charging ppl to use these shaders and post processes or something?(is what I'm getting at)


they are pretty good and there are tutorials out there which show you how to create a post process(for those other ppl like me who wanted to see a tutorial as to how he achieved certain things here).But yours are pretty useful is particular scenes and visual styles.If anyone wants to get into post processing go buy and check out Eat3D's UDK Lighting & Post Processing.It will get you started on this area of UDK

very nice :)

[KingBadger]

Hey Independant, love the work bud. But enough of the foreplay, when are you going to release the tech or is it going to be on a basis of purchaseing. would love some of these effects for my projects.

Also any chance you can start work on a Post pro shader for vector based motion blur like was first seen on project offset years ago.

Plus i found a demo of particle based rain system that runs on GPU at the following site:
http://developer.download.nvidia.com/SDK/10.5/direct3d/samples.html

Video:

Could you mess with the source and make HLSL version for udk.

P.s If you need someone to help testing these effects contact me by PM on here i would love to play with this mixed with my scene's.

first of all I want to get a feedback of my work.. so I posted my stuff in the Work in progress section (there shouldnt be a problem tough).

Eat3D´s UDK Lighting & Post Processing (no advertising please)
doesnt lead in the direction how I do it... There are no tuts for Udk,actually no one helped me aswell.. kinda selfish that alot of guys are asking for tuts..
e.g I asked how to convert the fp16 depth to fp32... no answer at all :confused: I figured it out my self..

Just pm me and we can get into business if you are realy intrested :),but don´t forgett that this is still work in progress..


@KingBadger

I won´t do a PP wich was made before. Udk´s Motion blur is excellent and fast.It´s useless making kind of slowmotion within a game. Just for showing the effect.I work on a better averaging of pixels this time..


atleast you gave me a Post process. Guys if you know some Post proceses wich I didnt made before then tell it to me.

[Chan]

I don't know how writing shaders for UDK compares to Crysis, but this guy has made tons of shaders for Crysis and he might be able to help you out.

Hi,
I made a Custom Bokeh shape test.. just for showing ..

http://up.iranblog.com/Files7/de0086d9974a485690d4.jpg

[Hboybowen]

first of all I want to get a feedback of my work.. so I posted my stuff in the Work in progress section (there shouldnt be a problem tough).

Eat3D´s UDK Lighting & Post Processing (no advertising please)
doesnt lead in the direction how I do it... There are no tuts for Udk,actually no one helped me aswell.. kinda selfish that alot of guys are asking for tuts..
e.g I asked how to convert the fp16 depth to fp32... no answer at all :confused: I figured it out my self..

Just pm me and we can get into business if you are realy intrested :),but don´t forgett that this is still work in progress..

thats all cool but no one cant be selfish for wanting to learn.I am just abit upset you wont show others how you created this or any other post process.

An would you by chance have a theory on adding Real Time Fur to UE3?

"Eat3D´s UDK Lighting & Post Processing (no advertising please)"
an the first thing you learn about this forum(i learned the hard way) is that even though this may be your thread you cant make rules for one thread that isnt present everywhere.Point being ppl can do that as long as its UDK related

[KingBadger]

Independant, which post process were you talkingabout?. Are you going to make a post pro GPU particle system or a new version of Vector based motion blur. By your post it sounds like your going to do your own Vector based motion blur, that would be handy even though you say the motion blur in UDK is good ( I Dissagree) even though it is being improved on in each build but vector based motion blur will always be the best and most accurate way of doing motion blur. But the particle system would be super handy as post pro if you can be tempted to create your own version. Also it would be nice if you could share some of these developments as we are supposed to be a community on here and share developments and resources. I set up a thread called Weapon MK18 model and scripts which i added to with another new test weapon so the community have a good starting point to develope for them self's. Im also working on uploading a model pack of 40 Assets that people can use for there scene's from Arch Viz testing that ive been doing, Shareing is the basis of Indie development. If you could be pursuaded to share some assets it would be great if not this thread is just kinda a sales pitch for your work (which is fair enough i guess but a bit tight). Peace!

Video of Motion Blur,and how it needs ALOT of work:

http://www.youtube.com/watch?v=hstQr7G4E_8

P.s This scene was created by Ellude who then SHARED with the community but has my own post pro setup includeing color screen mat filter,dual layer film grain, dOF hack shader(not physical).

[Independentsoul]

I won´t do a PP wich was made before.

means no motion blur. as you might saw I work on my bokeh and averageluminance for tonemaping

Hi,

http://up.iranblog.com/Files7/de0086d9974a485690d4.jpgIs this the same thing as this?
http://www.geekologie.com/2009/08/bokeh_filter_turns_light_blurs.php

I for one enjoy all your work and would like to see a showcase of everything you've created soo far, no matter if you plan to release it for everyone or not :)

For some post processes you could probably do some celshading, or even better, do an watercolour-esque post process with brush strokes for motion/edges ;)

I'll keep in mind you want more postfx/shaders to try your hand at.

[Independentsoul]

ya its the same thing but I discontinue this one. doesnt work probably :(.

I will make my hands dirty later on with cel shading and such stuff.

more easy then calculating a hexagon.. ((3*sqrt(3))/2)*pow(a,2) :p

[Independentsoul]

Hi,

Finnaly found a solution how to get Custom Shaped Bokeh Working.
After long 7 hours of developing it I have some acceptable results
I can make now every shape I want to with just some little changes to the Post process :D btw this is 4 times faster then my other bokeh

Here I made a Hexagon with an edge :

Here I made a Heart just for fun :

Really nice work as always!
How is the depth for the occlusion calculated? Through an additional height map, or do you do some wizardry with the normal map?

Also, what's the performance impact of these shaders? ;)

[samuraiwu]

It's amazing！Thanks！

[Independentsoul]

its directional lighting no occlusion. I could make a occlusion via the normal map .I make some ubdates with little occlusion maybe later on :). thnx


the performance impact is dependent to the steps used in the steep paralax shader. quite a performance eater with 12 steps



This can be used aswell for Fur because someone asked me to do it.

[TheDopefish]

Fur makes me think about this (Shadow of the Colossus):

[Xendance]

Have you thought about a way to blur those steps in those really steep parts? The steps are really noticeable :\

[Independentsoul]

@ Xendance: Yes I tryed to make smoothsteps no luck yet .. Need some papers..


If you take a look at the Gran turismo 5: X1 Prototype Trailer TGS 2010 http://www.gametrailers.com/video/tgs-10-gran-turismo/704778 then you see the same bokeh wich I have. I´m pretty proud that they have the same as me :D

[TheDopefish]

Interior mapping looks really neat :D

We use something similar at Starbreeze for our games, but that only simulates one parallaxed plane rather than being able to see the floor and ceiling.

Hi independed soul. =) your great,you said that you will help me with parallax occ right? ok anyway

heres the NFAA trying XDD :

DOes it setup good? or maybe not far from good? thats only the first part.you know. float topHeight = GetColorLuminance( tex2D( ColorTextureSampler, i_TexCoord.xy+upOffset).rgb );
and so on.so waht do you think about it? :DDDD will ibecome a good shaderist like you? xD

[Independentsoul]

I cant see the nodes you should sort everything and then send it up again with the ["Screenshot"]["/Screenshot"] function .. Maybe you can get like me if you practise more :) I would start making hlsl shaders best way getting advanced I guess :)

desert eagle, I think you need to move around your nodes a small amount to clean up, making it easier to see how they connect. Like the "Minus" you have in the middle, move it much further to the right, to avoid soo many lines crisscrossing all over the place :)

And now when I look closer... wow, that's alot of multiply's and adds ^^


:D I know right thats somewhat of what I been saying. You cant do that without a license. Its illegeal to make money off any form of UDK without a license.correct?
Good point. Think you may earn up to $5000 before you have to license? *looks up*


If you are creating a game or commercial application using UDK for sale or distribution to an end-user or client, or if you are providing services in connection with a game or application, the per-seat option does not apply. Instead the license terms for this arrangement are US $99 (Ninety Nine US Dollars) up-front, and a 0% royalty on you or your company's first $5,000 (US) in UDK related revenue, and a 25% royalty on UDK related revenue above $5,000 (US).
http://udk.com/licensing

I wonder how fine line they draw about this, since people can take fee's for providing other content for UDK, but then they are mostly created in external programs. Hmm...

my shader is just working on the "UV edges" where the UV is getting bigger then the original
if(coord.x> (fUVtile)){ return xxx;}

Some questions did you find a way to make rtt´s in a shader and using gradients in a loop? for improving the performance on low steeper angles for examble.

[Independentsoul]

@Deagle I´m sorry but I cant see any usag of those vector calculation do something like a pseudo code e.g
real code =
(tex2D(SceneColorTexture,ScreenUV)+tex2D(SceneColo rTexture,ScreenUV+half2(1/height,1/width))) /2

pseudo code =


SceneColorTexture with Screen coordinations + Scene ColorTexture with Screen coordinates wich are added with 1 texel and the addition of both textures divided by the sample average = blur

[Chosker]

very nice looking.

I'm implementing a few of these myself, and I have a few questions if you don't mind:
1. how did you get access to the luminance texture for the Dynamic Auto-Exposure Tone Mapping?
2. how are you making that auto-adjustment be over time instead of instantly?
3. can you explain a little about Screen-Space Color Bleeding? is it even visible in those screenshots you're showing?

thanks

Have you thought about making anamoric lens flares and lens artifacts?

http://www.deep-focus.com/dfweblog/images/480_AR_alien-lens-flare.jpg

Like Kane and Lynch 2, but not as strong.

I'd do it but I don't know how.

I saw "Anamorpic lens flares" previously on crytek mod page I maybe make it as soon as I have my working station back. I was playing the kane and lynch demo 3 weeks ago~ those effects would make it actually more realistic due its artifacts known on bad lenses or bad compression. the pixelation is quite easy did it some times ago while I stumbled over downsampling ( you might saw it when you shoot someone in the head then it gets pixelated in KaL2)

thnx Chan for the ideas :) I like the screenshot I will analyze it now.. and I make a hlsl shader for the anamorphic lens flare due its coolness :eek:

[Chan]

Yeah.

I think a subtle combination of all these effects could make some pretty amazing visuals.

[Independentsoul]

I finaly fixed my working station.
I made Anamorphic Lens Flare today its awesome how it enhances the feeling of watching through camera lenses ;)

it has 32 samples . its wideness is achieved via downsampling.I hope you like it :cool:

[ivangraphics]

What's great is when it appears off screen [as if object lights behind the view edge like in the last star trek movie] rather than all the way in the middle as it is now. Also it's kind of weird that things glow same color and weak light sources also cause it but i belive its just not complete so ignore me :) ... But overall the thing looks nice...

[CoffeeGrunt]

I wish I had a PC that could run those visuals, they're just insane...

Do you code the whole lot in HLSL, or use parts of the existing material system alongside it?

[Independentsoul]

I´m coding the most because I have to do alot of loops and its faster then drag and dropping every material node ;). I just can recommend it
e.g I can´t acces the Screenposition per hlsl so I have to input it manually with a material node .. Input.Screenposition.xy

I have killed the sharpness via a 2D Gausian Distribution

(took me 1 day understanding procedural weights ^^ ) the strange thing is the procedural weight is faster then a manual weight :confused: hope someone can explain me that

the Next thing I want to solve is no haloing or leaking around the focus.. should be easy but time wasting due its pretty scale.

Fantastic work, man. That blur looks damn good.

Thanks KazeoHin :) I´m doing my best
do you have an idea why weigts wich are calculated on the fly are faster then a constant weight matrix ?

[Analdin]

Dude, this is simply awesome! You should sell licenses for that stuff!

[CoffeeGrunt]

I like how you've given up numbering the volumes, but it's better to know this beauty's getting close to finality...

That blur shader is beautiful, maybe it having to load up the constant requires more computing power than simple creating it? It's weird, but perhaps some little, convulated way in which HLSL works means that it's faster?

Looks soo much better.



The lens flare looks a bit too strong at the moment. I would only have areas that overbloom create a lens flare.

Can I see a video of it in the tunnel level?

[Allar]

Sometimes simple math calculations are faster than a matrix lookup. Sometimes the GPU kicks ass with matrix logic but occasional theres an instance where theres a bottleneck either due to how the shader is compiled doing something weird to the performance of intrinsic functions or simply the hardware in use.

At least thats my experience <_<

[Independentsoul]

Thanks Guys for your comments :) I will make another lens flare today starlike bloom,glare/flare.

Thanks Allar for the answer stumbled over the question why it is faster ^^
I try now to make a bokeh weight calculation.

Here the hexagon formular... I need to get it in 2D space edit :(t=x*y)

http://upload.wikimedia.org/math/5/9/b/59bcfe4ec25f420df2f61c70fef53571.png

its ~3 times faster.. because the matricies are damn slow :( ... by the way I found a bug.. when using a Kernel and subtracting the kernels by 1 and the squareroot of it then the screen is flickering I guess its due the shifting of each frame.

http://upload.wikimedia.org/math/d/d/e/dde001b3b87bbed3f6f6edf7583ed5a5.png =1 unit Circle

Here the formular wich causes flickering in HLSL... I hope some devs know the answer

[Independentsoul]

Big Improvement! I have now 80 instructions instead of 180!! I can go now much further with more samples and I have now calculated the Bokeh/LensBlur weights on the fly and Instead of the gaussian distribution I use now the bokeh weights for even more accurate sharp edge reducing

I sure hope you can figure out a way of getting these into the hands of the community. There is SO much to learn from here!

[TheDopefish]

How's the anamorphic lens flare blended into the scene? It looks kind of half-transparent and too weak. Also, it's kind of hard to tell from the screenshots, but it looks like a unified blue, rather than a white that goes into blue (like HDR).

Further, they look a bit too thick, like if the whole light source is being stretched sideways, rather than a thin flare.

Compare them with the ones from Deus Ex 3 and you might know what I mean:
http://www.youtube.com/watch?v=hKj7FD4IaaQ&t=11m10s

Other than that, great job as usual and it's really good that you're able to optimize these shaders! ^^

Thanks dopefish :). allright didnt thought that there is critic on the pp but I will solve this tomorrow.

Seems like the things in focus still get blurred around the edges surrounded by foreground/background. Is it possible to use the depth buffer to mask out those areas so they don't get included? :D

[Independentsoul]

this is what I actually did but due the downsampling and the stride bokeh blur for the near depth it will be unprecise but its by far better then sharp edges :p

focus= halo issue
out of focus = precision issue

[TheDopefish]

Maybe this paper/presentation could help? :o

I used this before. but it uses some rtts so no luck

[CoffeeGrunt]

That comparison is sweet, personally didn't notice the blur issues at first until they were pointed out...

I'd be happy to have this in a game anyway... :D

Quoted for truth. This is still kickass, and the critiscm is becoming very picky imho :D

Independentsoul, have you done any good shiny metal shaders?
I haven't seen any good ones done with UDK yet.

[Independentsoul]

by the way DopeFish it is harder then you might Guess making such effects!

I have made them during optimizing and looking in the net . I hope you like them.. they are based on the newest Tri Ace Technology Fresnel Coefficiency of 0.05 and Specular intensity 1 and I use Ward and Ashkim Shirely Anisotropy of half2(100,10) everything is custom
They are mostly Correct to physical numbers but aproximated ofc

I hope The developers will make a deeper support for Sources and accesing External Functions or Variables within a Custom Node. Like PreviousWorldPosion or PreviousProjectionMatrix //some are working but not all

Here the Formular I used for the Coeficiency:

by the way I changed my Chromatic Aberation from yellow-red to Blue-cyan Smoothly


Left is Billiard shader middle is Metalic and Right is two layerd Polished smoky Glass

note: 1440x900 Resolution
http://up.iranblog.com/Files73/65f361143ff24a1bb7d1.jpg

note: IT looks better on more complex meshes. If you have metalic objects then support me with them please :)

[CoffeeGrunt]

Reminds me of ray tracing pictures for some reason, the reflection is pretty accurate...

These effects seem pretty good for making a photographic type game. Maybe something like a stealth-based reconnaissance game, where you take pictures of enemy deployments and such without getting found?

[Hboybowen]

did you get anything for hair/fur I remember it was brought up and looked at in the past I know a few ways to do it but not dynamic at all or affected by any form of physics

Any game using aiming would work really cus then you focus on the midpoint of the aim. But yeah photographing thing would be cool. Then the halo-thing wouldn't be a problem either!

This work really brings out a new level of realism to gaming.

Thanks SageHunter .Actually you filled my heart with love saying that the "halo-thing" is no problem but I guess if it is fully without Leaking/halos then I might get more customers or lets say more intrested people.

[Independentsoul]

I made a big update on My realtime Car/Metal Shaders and my glass shader in use with a Model (Zonda-ish car) wich Analdin of OrangeCore gave me to present my Shaders.

http://img262.imageshack.us/img262/1989/orangecoreweb.png [OrangeCore Logo]

I was sending yesterday an application to this studio

Those Shaders are Physicaly but aproximated for a better usage in realtime.

I have to say, the Zonda-ish car (It's not actually a Pagani Zonda, but we had it in mind when contructing the model) looks really awesome with your shaders!

[TheDopefish]

Oh my god. After checking the newest shots... If I didn't know, I could easily be convinced these are realtime renders...your post doesnt make since at all. All games are RT thats the pointI'm pretty sure he meant he would easily believe these images to be prerendered? :)

I don't have any suitable models to test the metal shaders on yet, but I think it would be easier to tell how they look in an cleaner environment and on video.

I believe a big part of what makes it look like metal is how it handles the specular, which would be easier to tell in motion. From the car shots alone, it looks pretty decent, but it's hard to tell :p

[Independentsoul]

hi dopefish,

I might make some vids of it. I´m now a member of Orangecore and if I sign the Contract for clysmic studios then I have 2 working stations :))

I think you will see some Vids soon on my Channel or at OrangeCore.. by the way the specular you see there is the most expensive- realstic.. its Ashikim shirely and ward aniso + ward iso
so 3 layers of specular

but I think the Metal shader is realy useable due its correction

[TheFallen1]

GREAT JOB. do you have a job doing this yet, if not people dont know what they are missing out on. :)

edit: never mind about the job thing i didnt see the last post :P

(little side note for Analdin)

If anyone has Ideas what I could make then please give your suggestions to me via yahoo MSN(new) or within my thread . :)

commenst are apreciated

[Independentsoul]

I have looked at my Screenshots and analyzed all my Visual problems I have in the moment. Then I had an Idea its pretty simple, kinda strange that I just make it now and not earlyer.

I´m making a near blur to get the sharp edge issue out of the way wich is currently in distance.

This process is shared this means my whole CoC gets blured now if the sharp edges are appearing on distances then I have to kill them via my bokeh distributin wich I´ve made previously.. so I won´t have the problem wit the sharp edges at all..



if I can make it then I just have to kill the Halo/ leaking around the focused pixels... but its harder then you migth guess filtering the blured bright pixels from the Dark unsquinted pixels :confused:


I will post some screenshots soon. Keep update :)

[Independentsoul]

It worked!

I have now a neat and correct result on distance.. I saw that alot of bokeh filters have this issue I have workaround it :)

Without my new method

http://img340.imageshack.us/img340/737/image154k.jpg


With my new method.. Kills Leaking on some spots and fully reduce Sharp edge problem on distance.
http://img63.imageshack.us/img63/7167/image153rr.jpg

[Independentsoul]

I was reducing the space/spride within a blur now..

looks by far more smoother and defined http://img219.imageshack.us/img219/1036/image165j.jpg

great work man keep at it. :)

Thanks . OrangeCore (including me ) are curently optimizing the Zonda(ish) car.
keep updated!

Yeah I had a slight grammar breakdown... I was tired.


Man this is all so great!

[Independentsoul]

Hard to belive that everything in my life is going the right way in the moment.

[CoffeeGrunt]

Wow, that Zonda...ish car looks, like a max render. I've always believed realism is purely down to getting the light levels to look real - you've proved it.

[Independentsoul]

Hey thanks coffeeGrunt I will post a screenshot soon of my Current Work wich has nothing to do with forests... completly realtime. the forest isn´t real to what I have done currently .I´ll show you it until it is perfect :))

does it work on convex surfaces? because if it does, we have to talk.

[Chosker]

seems like the usual multi-pass shells fur method. the tricky part is getting UDK to do the multi-pass. care to elaborate a little on that, Independentsoul?

KazeoHin: if it's the usual shells fur method as I presume it works on convex surfaces, its just that the fur shells would go inside eachother. I'd say it would look fine

[Independentsoul]

well Chosker: it isnt the multi pass shell method ... its steep paralax mapping

[shahafyz57]

can u put some blur effect on the fur? to make it look more dense? something like
http://udn.epicgames.com/Three/rsrc/Three/CreatingHairUsingAlpha/Hair_07.jpg
the hair look a little blurry

[Dralex789]

Wow, incredible work. If I am correct the multi shell shader works like this?

http://www.xbdev.net/directx3dx/specialX/Fur/index.php

While the parallax method is the example in the "mastering unreal technologies volume 2"

That fuzz effect though is done through opacity of the material right? So it wouldn't work on anything other than round objects. If not then wow, please share :D

Keep up the awesome work. You have almost inspired me to learn HLSL in my spare time

hey nice that I inpired you to learn hlsl!.. hey but is steep paralax mapping realy in mastering unreal technoloies volume2 ? And I have to say again my method is not using multiple faces... it is a very high quallity steep paralax mapping... It is so precise that you just have to use more steps to get a Real Neat looking Virtual geometry shader!! Well the edge detection does work on every object but the graphics are not high quality on complex shapes indeed

[Dr Bearhands]

Cool! Do you have a video showcasing the effect somewhat better?

[Independentsoul]

I will make a vid as soon as possible. In need of time !

[leviatan1001]

Awesome work, congratulations.
Im quite interested on making my own experiments with custom HLSL. I have made a black and white post process. But, could you please post a simple example of something more interesting than my example?, hehe. Some kind of blur or whatever.
Thank you and keep the good work ;)

A gift for noobs like me, B&W shader :D


float3 Color;
Color = tex;
Color.rgb = dot(Color.rgb, float3(0.3, 0.59, 0.11));

Xtreme sharpen effect xD

[TheDopefish]

I think using the "custom" node in the shaders for UDK is inefficient in comparision to using the preset nodes. I might be wrong though :confused:

Xtreme sharpen effect xD
Haha, nice one! :D

[Independentsoul]

edit: really nice scene !!! leviatan looks like you used the ambient lighting of the GDC demo.

well nice to see someone else starting to make visual effects :)... actuallly sharpen effect is a blur but the negativ way . the neighbour gets 0.5 in a blur in a sharpen filter it gets -1. pretty nifty:) but I did it myself aswell ^^ but alot of my mates said they dont like it :( so I dont use it in my shader pipeline.. keep up!!!!

[Independentsoul]

the luminance calculation can be made in a single line (BW)


return dot(tex2D(SceneColorTexture,ScreenUV), float3(0.3, 0.59, 0.11));

btw I found a bug somewhile ago... epic´s september build produces a buggy imagegrain!

All my work is in the Paze wallpaper :D :D

I have a question,
Is this a bug? As you may know, it happens after opening other rendered windows such as material editor or game running window:

[CoffeeGrunt]

Looks like a chromatic aberration effect...

[leviatan1001]

Looks like a chromatic aberration effect...

It is. But the effect in the viewport gets ****ed after a while.

[Independentsoul]

well I dont have this bug on my sept build (didnt tested octo build yet). I guess you just have a too high offset factor. Use instead of a simple factor for the offsett of each component this formular:




float2 resolution = float2(1920,1080); // your screenresolution x=width y=height == x=1920 y=1080
float2 Stepsize= float2(1/resolution.x,1/resolution.y); // this is your offset factor

note: here the example of how to use this code
return tex2D(SceneColorTexture,ScreenUV+float2(0,Stepsize .y); // offset in the positive y direction :: unit = 1texel

if this doesnt work (it should cause I use it :p ) then post the code you use to make Chromatic Aberation in here and I will fix it if you want to :)

I'd be happy for the material shaders. I can understand why you can afford all this shader detail now. Much less AI, level design and such required for a racing game than an FPS...

Only partly true, mate ;)
While there isn't that much detail in a racing level, the thing that eats up the performance is just its scale. Racing levels are extremely huge sometimes, and if you don't tweak the LODs and view distances right, you can easily get 2FPS while playing :D

I was curious to see if you've tried your hand at the interior mapping yet, since I believe that's something you could really utilize in a racing game :D



Think it's just a simple depth parallax as described here:
http://developer.amd.com/gpu_assets/GDC06-ATI_Session-Oat-ShaderTricks.pdf

I'm not allowded to share any actual code from the Starbeeze engine due to legal reasons, and anyhow, it should be easy for you to create such a shader.

If you're talking about the interior mapping, there's description and source code available fot it in this thread:
http://www.ogre3d.org/forums/viewtopic.php?t=30275

ok, no problem I will try to take a look at the shader as soon as I´m able to use udk again because my Desktop PC is totaly broken .. No safe mode and no normal boot possible .

Great shader..your really good at what you do..goin to try it..
ahm I was hoping for a shader that looks like this actually sorry for not being clear,I handpainted the texture for this one but the sketchy pencil effect on the shadowed areas are post. So I would really appreciate it if you could recreate a shader for me in this style. To be specific black outline then pencil sketchy texture set to multiply mode only on shaded areas..THat is if it ain't too much to ask.Thanks for your time..

keep in mind that I spend maybe 1hour on this shader.. I wasted my time abit to share that -- well I maybe do this shader soon. you should detail your questions in the near future-just a tipp.

Apologies..I really should have been more detailed with my requests..I would still be using it though & of course I would credit you for it.Thanks & I hope you could help me with the other shader..

[Count_de_Money]

My question: It seems that this effect is in everyspot where a reflection is ... is that true?

Effect is much more noticeable during night on wet surfaces, you can see it best when it's raining. Why it happens, my guess is that it's because of the water surface not being perfectly flat (asphalt is wet, but the surface itself is not smooth) + viewing angle + light source.

Now see some pics here with puddles, here we can approximate that the surface is smooth and acts like a mirror, so we have a different situtation.
