Developer Notes

User in the AnswerHub post noted he was able to use distance fields for collision as a work around, but not getting as nice of a result.

Description

Whenever a particle system utilizing GPU sprites with collision is enveloped within a planar reflection bounding box, the collision stops working.

Steps to Reproduce
  1. Open attached project
  2. Drag a planar reflection actor into the level and make sure the particle system is enclosed within the bounding box

RESULT
Particle sprites fall through floor

EXPECTED
Particle sprites continue to collide with floor asset
