Bug Red errors when using particles collision

Hello,

We're making a project that uses particle collision to detect and trigger something on our enemies.
However we're having these errors everytime the enemies touch the particles:



We've gotten this error "fixed" when we disabled "Velocity over lifetime", however if we do that, the particles fall below the floor (they're supposed to be static).

We've searched for this error and it seems it's fixed and then comes back, depending on the Unity version people are using. Currently we're using Unity 2020.3.16f1.

Any help would be greatly appreciated!

 

Hi, thank you for your reply!

We'll submit a bug report however we can, but wen't can't give any details about the project itself. We'll try to replicate on an empty project and submit from there!

We're not doing any operations on scripts with the particles, we're simply setting Velocity Over Lifetime to 0.

This error only occurs at the time of collision. If we disable the collision checkbox on the particle system, there are no errors popping.

 

So, a little update about this issue.
We found a workaround for now, but it's not pretty.



I guess the speed modifier being at 0 was the culprit here. We just set it to a really low value and visually it does the same thing, except there are no AABB errors. Hope this helps!
