I've been studying the possibility to make a chromatic aberration effect by using native wz4 tools. The best solution I found was to use ModMaterial channel masking + slight amount of Crashzoom effect + Rendertarget Layer2d compositing. Eventually that approach didn't prove feasible: to split RGB channels properly I had to copy each material 3 times and use a separate rendertarget for each one. It's too complicated...
Instead I used a CustomIPP effect based on this shader: http://www.francois-tarlier.com/blog/cu ... on-shader/
I slightly modified it so that individual RGB channels are available for tweaking. Many thanks to the author for a wonderful and simple solution. Credits also go to ikam for the awesome custom IPP effect (how are things with ye, bro?
