Specifically, I'm looking for any way to see a collision-only item from a Mesh Library in a GridMap. (The tag says "tile map", which it technically isn't; but there's no option for a grid map and this seems close enough.) There's no mesh to draw, so I'm left guessing, or discovering by trial and error, where it is. Then I make a note and adjust it or remove it before my next run. Clearly this isn't the most efficient way of working.
If I could get the collision meshes alone rendered in the scene, this would make it trivial to use.
