So, I'm playing around with the new 3D features. I'm building levels by placing horizontal surfaces (floors and ceilings) in a layout, using Tiled Background objects. The walls are then generated at runtime by creating 3D shapes (cubes). It's working really well so far, but all of the surfaces are rectangular in shape.
I could use meshes to transform the surfaces to be arbitrary shapes, but then in order to generate walls in the correct places, I need to be able to retrieve the mesh points at runtime. Is there a way to do this, since can't find anything in the documentation?
