After having tried to figure out why the hell my textures weren't affected I found out it was caused by setting GL_REPLACE with glTexEnv by commenting it out.
As I've learned previously from one of my earlier question is this used to prevent the modulating of textures with any previously drawn texture/colors.
Now, my question is will this result in modulation again (I can't see it quite well from my scene) ? If so, how can I combine these two settings?
Please don't be shy of writing a big piece of text. Every little bit of information is welcome and can very well be used by this newbie.
