Oh thanks. That wiki has a lot of the info I need.
By being 2cm thick, do you mean 2cm thick distance between meshes or the bounds of the object? Right now, I’m just working on ugly gray under detailed mockup versions of my environment so I have a lot of paper thin wall polygons for where doorways end up not being created. Later, those walls will be pretty and detailed and probably not paper thin either.
Also I’m using use complex collision for simple during the mockup phase instead of having proper convex shapes for all the blocking areas. Would using thicker convex bounding boxes help?
