Hi nick0815,
I’m not seeing the same on my end with a simple newly created particle system and full screen.

In my example I am using a newly created Particle System with the following settings changed:
- Spawn: Changed Rate to 50
- Lifetime: Changed Min/Max to 10
- Added Collision Module: Damping Factor set Distribution Vector Constant to 0.5
- Collision Module: Max Collision changed min/max to 2.0 and 3.0.
Give this a shot and let me know if this is working. If it’s just your particle system that is doing this I’ll need the following:
- A detailed setup for the particle system to replicate the issue. (or a simple project that can repro this works as well).
- If you can reproduce using my settings above for a basic particle in your project, try using a new blank project and see if the issue still occurs.
Thank you!
Tim
