Hello guys,
I want to apply a post process shader effect (procedural starfield) that I have written to a sky box cube map, which is currently not really possible because the effect is made for pure 2D / screen space purposes. How would I convert or apply it to my sky shader which currently queries its color data using texCUBE()?
I'm working with DX9 and pure HLSL, no CPU-side / host application processing possible.
Any ideas?
