Odd. If you do an 'UpdateNormals ripple' before applying any of the visible properties, the EntityColor is not applied to the rectangle either.
Switching 'FlipMesh' to be before the visible properties are applied didn't change anything, so that's apparently not the cause of the problem.
Creating a brush and using PaintMesh and PaintSurface didn't fix the problem.
