Overlap events not firing on BSP brushes

Development Programming & Scripting

I cannot get BSP brushes to generate Overlap events when collision shapes overlap them. They generate hit events just fine, and if I convert the BSP brushes to static meshes then said overlap events fire just fine, but the overlap events don’t fire by BSP brushes.

Hi RhythmScript,

This is intended functionality. BSP brushes are not programmed to fire overlap, hit events, traces, etc. Their purpose is simply to block out levels, and transform into static meshes if necessary.

Thanks for the answer, i’ve been tweaking collision settings for an hour because my projectiles pass through BSP. It was working in previous engine version (at least 4.4) so i thought it was a setting i missed.

if, while using bsp’s you want to return an overlap or trace event, place a blocking volume around the bsp. The blocking volume should be picked up as you were expecting.
