I'm loving the new bob and banked dirt underside geometry, but they aren't available in stadium yet and the shapes are limited. So I made a WTMT set of the shapes, with a simplified mesh so it doesn't take up as much filesize. Unfortunately, its not really possible to apply the vista textures on items yet, so for now the items have castle brick textures.

Every block has two rotation points, so by pressing Q you can switch between road or blackroad height :)
