UDK Cross Processing Post Process
Another post process shader for the UDK, again inspired by photographs, this time Cross Processing. The performance impact is roughly 10%-11% - tested on a low end GT520 gfx card.

Looks nice!! Any chance you'll upload the material editor setup?
ReplyDeleteSure, I've just added a material screenshot.
ReplyDeleteThe texture does hold 2 greyscale textures, one for the image grain (red channel) and another one for darkening the corners/edges.
The color teint can be controlled by using different power exponent values for each color channel.
greetings
Where you got those two texture sample ?
ReplyDeleteHi, the screenshot is pretty much outdated - I've just added a new one.
ReplyDeleteWhat you need is a low res noise texture (e.g. 64x64 or 128x128) that's beeing tiled multiple times. One of those comes with the UDK stock content (EngineMaterials package). For the vignette effect I suggest to create a gradient inside the material editor (like shown on the new screenie) to avoid compression or banding artifacts.
