Dynamic shadows IOS

[sandrain]

Hello dear community.

Please explain me when i watching movie of Infinity Blade 2 i see good dynamic shadows.
When i try to turn on them in BaseEngine.ini i get bad result, shadows blinking and they are low quality and sometimes does not appear.

I tested on Ipad2 and UDK 2012-05-BETA

How Epic did this in IB2?
Thanks

http://forums.epicgames.com/threads/...le-in-July-UDK here is explained how to enable them by NickBullard, but apparetly they are kinda bugged and doesnt really work in a decent way in this release...

Dynamic shadows are enabled per device in IPhoneSystemSettings.ini
can be found here - Engine>Config>IPhone>IPhoneSystemSettings.ini

if you are working in May2012 or older, these settings will be located in the BaseEngine.ini
can be found here - Engine>Config>BaseEngine.ini

hope they take a look at this and maybe fix them..

you mean that you are all well with the shadows, exclude last version?

but I used May and July version and the quality is there as I have described in 1 topic.
I hope that someone would explain me how epic did shadows in Infinity Blade 2 for ipad 2

Dynamic shadows work fine in a very limited sense in May 2012. I have them working, but to do so I enabled it where appropriate (as already mentioned), then disabled dynamic shadows in the light environments of the other pawns and finally disabled shadow casting from any other static meshes with a light environment. Basically, ensuring that only the player character (it's an isometric-style camera) casts dynamic shadows. All NPCs will have blob shadows.

This works, reliably. But when I add a second dynamic shadow of ANY kind to the scene it seems to switch between pawns and objects so only one casts at a given time and flickers.

Regarding IB2, I am sure there are ways to get this to work correctly, but 99% sure they all require source-code access and larger alterations for your specific title. That's just my guess, though, I haven't tried (and don't have a source license).

Try going back to iphonesystemsettings.ini and making maxshadowresolution smaller and mobileshadowtextureresolution bigger. The first number is the size of each dynamic shadow, the latter is the size of the texture they're being rendered into. If you have two objects casting a 256x256 shadows into a 256x256 shadow texture they'll fight for the same space and your shadows will flicker. If you make the shadow resolution small, say 128x128, and your shadow texture resolution big, say 1024x1024, it will be able to fit more shadows into it. If you make the first number too small your textures will look pixelated though, and I ended up not using them because they're very slow.
