Bathroom visualisation (first UDK work)

[bukkit]

for a first try in unreal i have to say im pretty happy with the result. although, there is still much to learn and much to improve. hopefully the future projects will be reaching to photoreal look

Wow, very beautiful work, great job.

[seenooh]

Holy crap, that is amazing work. You used DX11 ?

[arcshiri]

wow, very nice!!!

[bukkit]

DX9, DX11 was lagging.. only the last shot with DOF is DX11

[seenooh]

Cool stuff.

Can you kindly give us an idea very briefly on what you've done to reach that level of realism?

[bukkit]

sure.

since my hard drive is in service , i didn't have my own works with me , so i reached for some evermotion scene, modified it and remodeled in maya.
rendered with vray. when happy with the results i baked the color, lighting and gi information right into textures

then i started to learn the basics of udk , imported my maya models into the game engine one by one, and assigned the baked textures to them.

after that it was just playing with the materials. it was kinda straight forward. textures, fresnel, normal maps and reflections. i used on one material both realtime reflections and fake cubemap reflections for more realism.

the real challenge were the glass and water shaders. most of work was done on them. the key imho is researching the materials in real world and pay attention to details. like the window glass shader for example giving a double reflection because modern windows are usual double glassed and so on.

after that i did a minor post processing. colors, fog, dust particles, and so on.

finally adjusting and tweaking the scene for better framerate.

thats about it

[Strich]

Wow Bukkit. That is truly amazing real-time work!
Could you provide some stats on stuff like FPS, polycount, what machine you're running it on, etc.
Finally, if your work is not copyright in any way, would you be open to releasing the map and shaders for the community to learn from? If not, no problems.

[bukkit]

the fps is about 35-40 on 1280x720 res. polycount is about 100k polys i guess. my machine is quite avarage
i would proudly provide it, but the problem is i simply cannot export it with frontend. the final exe simply crashes every time

[Strich]

Might be easier to just zip up the map and custom content.

[TheAgent]

bukkit i have been also using Maya for several years but never found out how to bake shadow maps to textures etc.

Either way great job.

Either way great job.

if you're using vray for maya, it couldn't be more simple.

you just select the geometry you want to be baked (must have good uv layout)

then you just set the baking engine from none to texture baking


that's it. i also recommend using render passes for higher level of control

Finally, if your work is not copyright in any way, would you be open to releasing the map and shaders for the community to learn from? If not, no problems.

i can give you guys some tutorials on this forum in near future if you want. for the glass shaders (which are imho the only complex ones in my scene) everything else is kinda basic. the fake glossy reflection was mentioned somewhere on the internet. the water is just modified waterfall shader from the folliage map

[TheAgent]

Very nice! thank you im going to try that next time

[horoxhoro]

200k tris? for a small scene...@_@

awesome are those realtime reflection from dx11? nice

[bukkit]

nope. the glossy reflections are fake dx9 reflections. the dx11 were very buggy with low performance. (to the polycount : especially those two towels were kinda overkill)

[ilguano]

Very nice. I really like the dx11 one

[keroki]

Yes please, a tutorial on how to do the glass would be awesome.

hi bukkit ,

Is your floor using relection actor or cubemap reflection? thanks

Hello, very nice work and I'm interested in performance difference between using UDK lightmass and baking lighting from 3rd party software. Can you replace textures with basic material in UDK, put couple lights, and build lightmass? I'm sure performance difference wont be noticeable since the scene is fairly small but would like to know the difference between file size. Thanks!

[mafiadude1]

amazing work! the last shot had me speechless :O

well im not sure about the lightmass performance. but the baked textures dont represent any performance hit at all. (depending on the resolution) i used textures up to 4K. the biggest performance hit were the real time textures. so i needed to scale them down to 512x512 max. and also the anti aliasing slowed things down. as for the file size. the map itself has only 187 kb. and the packages have 360 mb

[taz1004]

Package being 360mb is already going over the 300mb soft limit. On a such small room. Like I've said, you wont see performance difference on such small level but wanted to compare the file size difference on the level if you use lightmass.

yeah. its made out of two packages (290+60mb) and i really wanted some crisp textures and as many realtime reflections as possible. imho its ok, even for such a small area. im not planning to build anything much bigger (medium apartment would be the maximum level size in my case)

[PureFunkayy]

:O erm.... Wow nice work there

[PureFunkayy]

Totally random but, TheAgent I just checked out your website, wow awesome!

[SlothTech]

Thats masterful! Really well done on that.

[sustu]

Looks good.

[micahpharoh]

I don't know why I haven't commented on this yet, it's amazing.

[ShaneC]

Very nice sir!

[bukkit]

Warmest of thanks to Epic Games and especially to Paul Oliver.
I'm glad you liked my work and i really appreciate the awesome gesture

Thank you!

[TheAgent]

That is one sexy graphics card... GTX 580?

And thanks TAW Sn4ke108 :P

[bukkit]

not as classy its 460, but still a wonderful gift

[Count_de_Money]

It's well deserved.

Now please make a HD version of the video.

[Blizzard_Edge]

Very cool and clean. Congrats on the graphics card!

[amigoface]

great ...


can you share your materials please

i think that it can be very uusefull to have a materials database for udk with ready to use materials and effects

[bukkit]

great ...

the only interesting materials in this scene are the glass materials , i made a tutorial on how to create them, theres a link to it somewhere in this thread.

[amigoface]

yeah yeah i am aware of that
and i am interested in the glass material too

but i am a very very very lazy person

especially after several hours of day work

again
it could be nice to have an UDK materials database ready to use for various effects

anyway i will try to reproduce the glass tutorial when i get some time

[Warrior_For_God]

Love the textures, awesome work
