Delete element 0 from skeletal mesh

I’d like to delete element 0 from imported skeletal mesh.

The “delete” checkbox is grayed out (only on element 0, I can delete everything else, apparently).

How can I delete it?

Alternatively, how can I disable it during rendering? I’m talking about properly disabling any attempt to render element, not about “just put transparent material on it”.

You will have to delete it in your 3d tool -> it’s the material slot that you have made in the 3d program :slight_smile:

What determines which element is the 1st?
