cell with colour correction for bumpmap 2005-06-14 - By Schoenberger
Back
If you enable the bump mapping inside the Cell shader,
it is not possible to put any color correction after the shader node.
Cause the bump is not a color, it is a normal.
If you want to use color corrections or anything like this,
the bumpmap generator has to do the bump.
There is a workaround to get this done with procedural textures,
But only if the cell uses the first texture projection.
Plug a vector_state(texture vector) into the Cell coords, then the cell
into the bumpmap generator, don't enable bump inside the cell shader.
Or use my BA_Cell3d, there you have contrast/clamping control
and you don't need the bumpmap generator at all...
