Black ball appears while editing skirt

Okay, so I got this black skirt which is very tiny. When I put it on, most of it was inside my body, that's how small it was.

I start tugging on it to make it bigger.

When I first started editing, I saw there was a ball inside me in the middle of my pelvis. It was part of the skirt for some reason. As I worked on the skirt, the stupid ball suddenly moved out and hung in the air behind me. The more I worked on the skirt, the further behind me it moved. It was maybe a foot behind me, like the height of my tail bone.

I meant to take pictures, but some guy was yakking at me.

Does anyone have an idea what in the world is going on?

That ball is probable part of the LoopRez script (or something similar) used to help create the sphere of the skirt. It is getting bigger, along with the skirt panels.

I hope this is a copyable item. If so, attach a fresh version of the skirt, size it carefully, then, choose "edit linked prims," select just the ball, and reduce it so it hides inside your avi again.

Thanks! It is copiable. I did make a copy before starting, so I can go back and start over.

So is the black ball in the middle of an invisible sphere?

What is weird to me is that the ball is OUTSIDE the skirt. Is is like those rez boxes that houses come with?

Clever skirt and hair makers make a simple ball or cube the root prim of their object.

The root prim is where the object's center of rotation lies, so it's convenient to have the root prim actually at a point that's good to rotate around, like the middle of your pelvis (for skirts) or the center of your head (for hair)

When you re-size any multi-prim object, ALL the prims are scaled. So the ball got bigger and stuck out of your av. What the other poster is recommending is that you edit ONLY the ball now, and shrink it down and put it back in the center of you, where it belongs.

(Even MORE clever makers will make that root prim transparent, so if it inadvertently sticks out of you, nobody will notice).
