Please post any feedback regarding the Particle System Limiter here. Here are the current limits: https://docs.vrchat.com/docs/avatar-particle-system-limits
Here's what we'd like to know about your adversely affected particle systems.
How many emitters does it use?
Are they mesh particles?
Are they billboard particles?
How many emitters are active at any one time?
How fast do they emit?
Do they have collision?
How complex is the collision?
What layer are they colliding on?
Any and all feedback is useful, and we will use this feedback to help shape the limiter in the future. Non-constructive feedback will be removed.
