Sounds like you have a bug in your code. You shouldn't need to do any extra work to combine the texture with the output of lighting.
Keep in mind that the default GL_MODULATE is a multiplication, so red (1,0,0) times green (0,1,0) equals black (1*0==0, 0*1==0, 0*0==0). If something is happening to your texture coordinates, then the default (0,0) will almost certainly look up "black" as the color. And with GL_MODULATE, you'll get black. Just for testing, you might try setting GL_REPLACE for the TexEnv; you should just see the texture in that case. If that works, it means your texture isn't getting blown away and your texture coordinates are correct.

If I have just either material(ambient, diffuse, etc) or texture, it worked fine. However, if I have both of them, the geo looks black. Is there thing I need to do to blend the texture and the material? Thank you!
