I am trying to assign multiple materials to an object (to different faces). I understand that I have to have multiple materials, and multiple material slots with these materials assigned.
However, I am having trouble creating a material slot in the first place. I select my object, then, still in object mode, I go to Materials tab, then press + on the right of the slot list (A). Nothing happens (i.e. no slot appears in the list) (B).
I thought it might be that I have no material yet, so I pressed the "+ NEW" button below the slot list (C), created a new material, and with it still showing, clicked the + (A) on the right of the slot list again. Nothing happens (i.e. no slot appears in the list).
What am I missing here?
