so how can i render one of the object with diffuse light and the other without that, till now if i add glEnable(GL_LIGHT0),glEnable(GL_LIGHTING),glEnable(GL_COLOR_MATERIAL) to InitGL, i affect everything, so how would i go if i only want to affect the cube or the pyramid.

Move the glEnable(GL_LIGHTING) to just before the code that draws the object to be affected, and then put a glDisable(GL_LIGHTING) just after.

great, it worked, thx for the reply =)
