Register Combiner With FP ?

I use ARB registers combiners:
-Up to 4 texture Units
-With different operations types (Color,modulate,etc.)

I would like to know: if those registers are still activated when using Fragment Program because I only want one of both technique (FP or RC) activated when rendering.

I think when enabling Fragment Program the RCs are not available.But may be I’m wrong…


Yes, this is right. If you use fragment programs then the texture environment functions (or ARB register combiners as you named them) are disabled.
