   Materials change when texturing is enabled
  Materials on a model change when I enable texturing. I apply the material using glMaterialfv and everything looks normal. But when I enable texturing using glEnable, all materials turn dark, even without loading any textures. What am I doing wrong?   
Do you have lighting enabled?;  Yes, lighting is enabled and all normals have been set correctly   ;  What texture mode are you using?  MODULATE mode for instance multiplies the alpha value of the texture by the original color value of the material to arrive at the resulting color.  If the texture isn't loaded the alpha value might be very low or zero by default.   ;  Could you post a snippet of code where you initialise and load your texture and a bit of the rendering code ?
