Is there an easy way to detect unused material slots in an object? I have recently been importing and modifying models from sites such as CGTrader. When I work on the materials for models, it often seems that objects have unused material slots.
At the moment, I'm just going into Edit mode, clicking the &quot;Select&quot; button for each slot, then scouring the object to see if any faces are selected, before deleting the slot if it is unused.
However, it seems there should be a more efficient way of doing this. Can anyone enlighten me please?
In the 3D Viewport, in Object Mode, with the object selected, pick Object &gt; Clean Up &gt; Remove Unused Material Slots.
This also works with multiple or all objects selected.
