I noticed when theres no polygon or particle playing, the animator seems to stop updating to others.

I have an invisible toggle which toggles off all meshes and Plays a particle System

But as soon as i toggle my Avatar on, noone exept of myself can see me. I could recreate this in Unity by a non local Clone.

If i'm fast enough while the particle System is still playing, everything works. But as soon as the particle System runns out, the Avatar is not updating for others anymore.

I found a way to fix this by adding a cube on my Avatar with an invisible material on which is always Rendering. As soon as some polygone are playing, everything works. i dont know if thats intended or a bug but it took me defintly a while to figure out why my toggle wasnt working to others
