I am trying to make selectable objects

I have the cursor under the left elbow gizmo but instead the object that gets selected is one of the fingers

You may need to normalize obj.position - mouseWorldRay.origin before you can use it in the dot product.

And the same for closest.position - mouseWorldRay.origin, but I would recommend saving the closest dot product as well, so you don't have to compute it again.

I've got it working, just leaving these files as a note for myself 'cause I solved it outside my workspace
