Socket is greyed out and I can't attach anything to them.

Hi Everyone,

It’s been a while since I’ve used sockets but previously I could set them up, they’d appear red in the Skeleton Tree and I could attach other actors to them via the ‘Attach’ option in the right click menu in the editor viewport.

Now, when I open my meshes and look at those sockets, or try to add new ones, they appear grey and I can’t attach anything to them.

Is there a step I’m missing out on here?

Ontop of that, the socket bounds and the widget are scaled up by 100 when selecting the socket in the Skeleton viewer.

I’m using the MixamoMale skeleton.

No one answers because they are common sense questions, but beginners can quickly get an answer with a simple search: Using sockets requires a parent.
