The ever slippery MultitextureARB extension
Quick question about the multitexture extension.
I have set up GL so that texture unit0 gets assigned one texture and unit1 gets another different texture. Then I render a model and it appears to come out blended (albeit very dark).
[I'm using MODULATE for tex env 0 and BLEND for tex env 1]
My question is how do I access the various blending modes e.g. say I want the following in one pass..
(unit0)src GL_ZERO (unit1)dst GL_DST_COLOR
Do I need to go after the 'combiner' extensions?? or am i missing something?
I have had no luck finding any code *anywhere* not even on opengl.org to do this very basic task - this baffles me somewhat since gl has such a good reputation. Lots of people seem to be asking the same question on various boards but no solid answers.
Anyway if anyone could help me out I'd be most greatfull.
