Mesh Colliders
The ability to add a collider to a shape so that particle brush effects are contined within the shape and doesn't extend out of that shape. Not sure if there is a way to do this easier with a script.

This wouldn't be very easy as all the particle brushes are implemented using vertex shaders rather than using Unity's particle system. So there's no real physics going on. It might be possible to have a bounding box applied but that could look a weird weird.
It would be helpful if you could give a specific example - there might be another way to achieve it.
Got ya…. Good example would be a snowglobe where snow particle brushes are contained in a sphere.
Even though you can technically make the snow using perfect circle, they’ll always go out of bounds
ok. so maybe just having them disappear outside of a certain volume could work?
Yes
See lots of use for this besides snow globes
I wonder if this could be part of an extension to "grouping" - if you group inside (say) a guide then all brushes are clipped to that guide
That would be cool
there's a related feature I want - where brushes disappear if they are older than a certain time. So the common theme here is having brush strokes where parts are invisible if certain criteria aren't met.
