Particle system disasters if I edit the mesh im animating my 3d character and im wondering why when I delete any vertices from the character mesh, the particle system attached to that mesh goes all over the place.
Any ideas?
I'm assuming this happened with hair particles that were combed? Particle rely on faces and vertices, if you have 101 vertices and you delete no. 40, 41-100 have to change their index. Since the particles are linked to the indices, they go berserk.
The short answer: Don't do that. If you really need to remove geometry, use a mask modifier after the particles system.
