How to show object-color through light-color?

say I have a triangle with different colors on every vertex, smooth-shaded, and I want it to also work with lightning - how is it done? I don’t want to use a shadow-map etc…


Just change your material parameters at each vertex.

yes, thanks… glEnable(GL_COLOR_MATERIAL) was what I was missing :slight_smile:

Can I display semi transparent polygon in PseudoColor?
