Sure, it's still possible...
You can use umm... I forgot the code but I think it should be:
Code:
ColorOps[X]=Add;//Where X is the stage number range from 0 to number of layers

You can change Add with Multiply, Multiply2X or Multiply4X...
Hope it helps laugh

[EDIT]
You can also add a bump map using
Code:
ColorOps[X]=DOT3//Or something like that


Sorry it's been a while since I do 3DGS and shaders...
