I have come across a problem with a few of my blueprints. In many cases, I use instances of simple static mesh elements that have collision defined. The issue now is, that in-game the collision does not work (or is ignored in some way) for instanced geometry. It does work when I add copies of the same meshes instead of instancing them.
I would of course prefer to use instanced meshes for performance reasons.
Any ideas on this?
