Ok, I''ve recently run into a couple oditeys in my program. Fisrt, I have an object that has no textures just per vertex coloring. If I enable lighting then I have to enable GL_COLOR_MATERIAL or the object appears gray. If I disable lighting I dosn''t make a difference if I enable GL_COLOR_MATERIAL or not. Second, if I disable GL_COLOR_MATERIAL while lighting is enabled then it leaves the color at that time as the material color and put''s that over everything. If I put a glColor4f(1,1,1,1); command just before disabeling GL_COLOR_MATERIAL then there''s no problem but if I put it just after disableing GL_COLOR_MATERIAL then it has no effect. I''m wondering if that''s normal or what?

ok, thanks. I don''t always have time to read all the available sources for thing like that.
I was thinking maybe (but not likely) a diver bug so I''ve been trying to get the new device drivers from nvidia but all I can find are win9x/me drivers and no 2000 drivers!

I also noticed they don''t put there e-mail addresses on there site eather.
