Hey, It's not built in my default, although I think Fabrice has had some experience doing things like that for a project :) Sending out events from the BSP mesh itself is a bit hard and slightly pointless. Hard because you'd get a chunk of the bsp which probably wouldn't mean much to you as a "mesh". Pointless because in 99% of the cases (unless you're free-falling), you're colliding against the floor due to gravity. The best thing you can do is testing if your intended XZ position matches up with the actual position after moving it using the BSPCollider.
