Niagara distance fields collisions not working

Hi everybody,

I’m setting a Niagara system with GPU collisions relying on distance fields. The thing is the system works as expected while in editor, but particles doesn’t detect collisions when in play mode.

Update: I tried the system in a single level and it works. Collision evaluation is working because if I set r.AOGlobalDistanceField 0 particles collide when spawning and remain static at their initial position. Also noticed they behaves different when the camera is close or far away which would make sense if using Depth buffer but not with distance fields.

Any ideas why this could happen?
