As I understand it from your explination, it sounds like the strap and holster are seperate actors (body parts). You should not expect morphing the strap to move the holster, a morph only affects the actor it is applied to. You have two options. 1. Make a morph to move the strap, and another to move the holster, then make an FBM. 2. Use ERC to slave (probably) the translateX channel of the holster to the morph in the strap. Before you add the slaving code, set the morph in the strap to 1.000, then note how much you need to xTran the holster to put it in the right place, this value is the one you should use in the deltaAddDelta line of the translateX channel.
