20169	Hiya This got kind of big. I'm trying to accomplish some multitexturing in my little engine, but it refuses to work. If I do it multi-pass (drawing the same...	Tatsujin tatsujin@...	Mar 2, 2002 1:35 pm
20170	I'm not absolutely positive, but I think you cannot mix two textures by simply using the glBlendFunc. I've seen some code which used some other extension to...	Death Hunter mtk@...	Mar 2, 2002 4:19 pm
20171	I did have a look-around at some stuff on the net and found that you need to call glMultiTexCoord2fARB() for TMU's other than 0. And that actually solved it! ...	Tatsujin tatsujin@...	Mar 2, 2002 5:38 pm
20172	The blendfunc is used when combining the fragment color with the framebuffer. Multi-texturing is used to figure out the color of the fragment, and thus uses...	Jon Watte hplus@...	Mar 2, 2002 7:46 pm
