UDK Chromatic Aberration Post Process

Another post process shader for the UDK, this time chromatic aberration.
The performance impact is roughly 10% - tested on a low end GT520 gfx card.

The effect can be helpful to realize some kind of technical/electrical malfunction, espacially if it's 'animated'.
Perhaps you remember the nano suite in crysis at this point.

UDK Bleach Bypass Post Process

I have just built a bleach bypass post process shader for the UDK. It is based on the material editor node system, so there is no hlsl at all. The performance impact is roughly 10-12% - tested on a low end GT520 gfx card. Material paramters allow to adjust the overall effect intensity, brightness and desaturation.

What the bleach bypass basically does is creating a desaturated copy of the scene and overlaying it (this means screening the bright areas and multiplying the dark ones). This will result in a scene with less saturation and a higher contrast. For further information read trought this: http://en.wikipedia.org/wiki/Bleach_bypass

Damaged jersey concrete barrier.

The model is intended to work with the Unreal Engine 3 but it will work within other game engines as well.

Base model: 504 triangles / 342 vertices
LOD 1: 238 triangles / 185 vertices

[Update] UT3 Parallax Occlusion Material

The UT3 POM material has been updated. After some time I realized that there was an error in the first depth search, leading to wrong data on the first layer. I also changed some additional stuff like specular parameters.
