The distance field collision for GPU particles doesn’t work at all since no collision response option seems to do anything (Kill, Stop, Bounce).
Reproduction steps:
- create new project with Starter Content
- Modify the “P_Explosion” particle system from the Starter Content
- “sparks” emitter → Collision (Scene Depth) → Collision → Collision Mode: Distance Field
- project setting → search: “distance field” → check “Generate Mesh Distance Fields” → Restart project to take effect
- place modified particle system above static mesh with created distance field to see that there is no effect. (the shadow is due to a “garage” made out of box brushes → no distance fields)
The intention is to create particles even if the emitter is hidden behind the player or a static mesh from the cameras POV, preferably with GPU particles.
