Hello again, i have another question. Is it possible to have different specular levels in one mesh? If i try to do this by applying different materials to the faces with the materials having different specular levels i cant see a effect. if i set the specular level of the material to 0, i can see it. Then the result is like setting the specular level of the directional light to 0.
How is the correlation between specular level of the light and specular level of the material. I'm using DirectionalLight3D and PhongColorMaterial.
