Wierd moving thing in a cut model [2 Screenshots]

[BrothForMyPeople]

I'm editing Priestess of Moon to be unmounted, hovering unit.
Just one thing bothers me - the wierd moving hank of texture under the Priestess (looks like the tiger's texture).

As you can see, there's nothing on the Model Editor. I don't know how to delete this thing.

Nevermind. You can delete it in MdlVis program.

Problem self solved. Thread can be closed.
