I am implementing an OpenGL based facial rendering program for my senior honours project on mac os x but the model is too dark. I have ambient lighting set at max (1.0f,1.0f,1.0f,1.0f) but I still have trouble seeing it. The model has >65000 vertices. I have also rendered a texture mapped cube and that shows up fine. Note, the model has no texture mapping - just coloured polygons. I have tried altering the material settings with glMaterialfv etc. but nothing seems to make it brighter. Can someone tell me what I am doing wrong??

You could post some code... On the material properties you are defining

I'd also say that it could be an issue with normal values...if your normals are wrong (or none), and you enable lighting, it looks really dark.

How about using diffuse light as well... Not sure it wil help, but it''s worth a try.
