if i take a cube subdivide it then add like 2 3 materials for different faces
and then i select first material and add a new particules system
it looks like there will be a particules system added on each material
and i cannot have one particules system on only one material
i might use vert group to do it
but is there a way to add particules system to only one meterial wihtout vert group ?
there is also a tool tip like Shift X to delete but does not seems to work !
