I tried seperating a face from one side of a gear I modeled so I could apply a Particle spark effect to it. Here’s what happeens:
I select the four vertices and seperate the face that I want to apply the particles to.
I select the seperated face and add a new particle effect.
Blender crashes immediately.
I tried multiple times to get it to work and it always crashes, so I thought it might be a bug that won’t let particles work with seperated meshes?
