Skeletal Mesh Additional Body Part

Like the title says. I cannot seem to find this one the docs for any skeletal mesh page. What does this one piece of the skeletal mesh detail panel do?

I would also like to know what does this panel do.

Every time I click Add Mesh it just shows the characters mesh, is there a specific purpose for this panel?

Anyone figured out what the purpose of this category is?

I think it’s just for preview.

To check if everything it’s working how should. But if you want to really attach a body part in game, you have to use blueprint.

Thank you :slight_smile: Would be useful if they specify Preview there to make it obvious
