Thanks. I have just done this: I put the actor back for the neck, and the distortion got less. I put the actors back for the forearms, and the distortion got less again. I tweaked the Tran's of the wetsuit's hip and BODY, and the distortion disappeared. But, what is "empty actor"? Do you mean the initial "short actor", e.g.:- actor rForeArm:1 { storageOffset 0 0 0 geomHandlerGeom 13 rForeArm } or the main actor? By "empty" do you mean "delete all its channels" or what?
