I'll add two things to this rather than make a new topic.
Is it possible to fix the alpha? For example, if you make two boxes and blank the middle of each side (leaving the edges), then rotate/intersect the boxes, the boxes will both fully render from some angles but not all. Picture an old-school wireframe look.
Might not even be possible since I'm sure it's more of a "trick" than a full 3D object. It just would be nice if all sides were visible even when intersecting with transparencies.
Also, would love to see the ability to swap the texture on a side. Either through an event, or having an animation on each side.
