Surface
Click Technical view in the dock, then choose Surface color in Surface:
Every mode except Material is drawn without scene shadows, fog, or glow.
Turn Textured off to remove the textures; tint, vertex color, and lighting stay. It works only with Material. Wireframe draws mesh edges over the current colors. Grass and water do not get edges.
LOD colors

Surface color set to LOD, with the legend.
Use it to see which tier you are looking at from a given distance, or why a building changes as you approach.
