Well, here's an odd problem I'm having at the moment. Static meshes in my map are not casting shadows on BSP, but they are casting shadows on everything else normally. Moving the BSP or statics and rebuilding does not fix the problem. Duplicating the statics also does not work. So far, the only solution I've found is to re-add each static mesh (1804 total in the map) from scratch and redo their settings, not exactly ideal. I suppose redoing all the BSP would also work, but again, not ideal. Any ideas?
