Here are a few simple 3D shapes for you, useful for level design. Place them to create gameplay in your level, later replace them with good looking models of a similar shape. Comes with a block, a ramp and a bridge, as well as rails. All with Colliders, of course. UPDATE: Now with a pillar and a pillar edge. Download them here for free. If you have ideas for more shapes, I'll update this or collect them and someday make a second package for you.
