Direct3d Lighting Problem
Quote:d3ddev->SetRenderState(D3DRS_LIGHTING, FALSE); // turn off the 3D lighting
You don't have lighting turned on, so no lighting calcs are done. Change this to ..D3DRS_LIGHTING, TRUE..
This article describes what you want to do, I believe.

What's the question? [smile]
The diffuse component of the light is combined with the diffuse component of the material, as modified by the normal to the vertex - creating the look of directional light.
If you want directional lighting, both the light and the material should have diffuse components. Ambient light will be added to all vertices, regardless of the normal.
Does that help?
