Diffuse Texture Element Rollout

The Diffuse render element displays the diffuse color component of objects in the scene.

Lighting
When on, the diffuse render element displays the color of objects after lighting has been applied. Default=off.

When Lighting is turned off, the element displays the diffuse color of objects before the lighting gets applied. For textured objects, this will look like a 3D projection of the texture. However, objects with a single color will look “flat”.
