Advice with Particle system collisions behaviour

Hi i’ve successfully followed this tutorial but final behaviour is bit weird. I’m relatively new to UE4 :slight_smile: so i cant figure out what’s the reason to this behaviour. Can someone please direct me to any workaroud or solution to avoid it? Maybe i should mention that i’m using level streaming (world composition). To me it looks like problem with occlusion or maybe level streaming … First of it particles collide with landscape only in front (and sides) of character. and second weirdness is that its not colliding at all with some (nearly all) camera angles, as it can be seen on video . When i turn camera its starts/stops colliding in some angles. If i tried to reproduce this in blank template it was working as it should.

First problem was in Particle System Emitter rotation (my bad). … So now only thing i need to debug is that collision affected by camera rotation.

so ive managed to find solution myself (suprisingly) :slight_smile: solution was to turn of “Drop Detail” performance setting of actor collision in particle system … im still not sure why it was needed but at least it solves problem and collisions work just perfect now :slight_smile:
