I'm using a particle system as a smoke emitter (see here Creating Inky-looking characters in Blender ). Everything is fine but with simple particles, i don't have enough control on the movement of the smoke, so i need children. As simple children are really too ugly, i need interpolated children. But as soon as I activate them, all particles disapear from viewport and the simulation seems to use only parents (same as children deactivated).
no children: Simple children: Interpolated children:
My question is : is this a bug? can you use interpolated children in smoke sim?
