Dear all,

I have an OpenGL 3D application that requires lighting to make the surface more metallic and realistic

how can i turn something like this

I want the surface to have some metallic reflection but can’t find a way to do it properly.

Thank you for your help

Images are HUUUUUUUUUGE

use GL_LIGHT0 + GL_SPECULAR_MATERIAL or smthn. (forgot as I’m vp+fp’ing now ).
