Colliding particles with a static removing geometry 2025年4月15日12:38
MiloStormAs vicvvsh has mentioned, changes in point numbers cause the simulation to break!
Why do particles explode when I remove part of a collision mesh at a specific frame?

Thanks a lot.
Sorting point numbers solved the problem.

VortexVFXThank you so much.
I think the changing point count might be throwing off the deforming-geometry sourcing for the collider... it's more for actual deformation, not partial-deletion.
Try having each half be a separate, non-deforming static object, then just "switch off" the top one... not sure if there's a more elegant way, I've used a Switch DOP.
But the problem is that if you want to delete the primitives of the geometry dynamically during the simulation, this method won't work anymore.
I know that we can use volumes instead but I'm curious to know why this happens for surface colliders.
