How to kill particles that intersect geometry?

[velariakrah2002]

The MPM GEL emitter emits particles. There's geometry underneath. When the particles reach the geometry and intersect it, they should die. How do I do this? I can't find any guides, and the GPT chat doesn't explain how to make nodes either.

you can use a mask  + a kill influence to do that - where in the mask you cube input will be and make sure you pick Mesh in the geo shape of your mask node

It doesn't work. Did I do everything right?

just check absolute on the kill influence

I've encountered a problem. The method recommended above is putting a significant load on the simulation processors. Is there a simpler way to kill particles in a specific area?

then use a kill plane
