Simplest way to create oblique Pyramid

[systemsincode]

@systemsincode

Easier - have two pyramid mesh groups rendered in the same place using ‘out of the box’ geometries, but assign invisible material to faces that need the alternative layer number.

This works for me but now the Raycaster intersector is still selecting the invisibe/transparaent face. The new material face has visble set to false (the objects visible property is still true). Shouldn’t the raycater respect the visible-ness of the face?
