I need to emit thinking particles from the intersection of two objects.
I’m going to animate a growing sphere on like a street corner, and I want to emit particles from where the sphere is intersecting with the environment, if you get what I mean…
And no, I’m not getting x-particles right now, I want to do it with Thinking Particles

Hi, niklas.alden,

Please have a look into this setup.

The idea is that the Null is scaled. Since it is a parent to the Sphere and the Disc [emitter], it scales them both equally. The key is here to have the Null object on the same level as the Disc, in this way the Disc stays on the floor level.

Let me know if you need it differently or have another question. I’m happy to look into it.

All the best

P.S.: some variations…

Please note that often a Cloner Object set to Multi Instances is a faster way than to use TP-Geometry.
