This was a simple case to test something: e.g. I want to set up a man wearing my flamethrower model, once, and then export the relating positioning of his hands and its gun part, and lines setting particular IK chains on, and parenting the end part of a set-ON IK chain to some part of the other model to make a circle of linked parts, and so on and so forth, as a pose or similar file, so I can quickly put my flamethrower, or my scuba set, or my frogman's rebreather, or etc, on any Poser humanoid model without a lot of tedious re-posing of the arms and hands and fingers etc every time. - I made a pose of the man as when wearing my flamethrower, and a pose of the flamethrower as when the man is wearing it, and ditto with a man wearing my oxy-gas blowtorch with backpack cylinders; but those poses don't get the two models into the correct relative positions. - In particular, I want to do this to get my frogman's rebreather diving set's mask to automatically go onto its user's face if desired. That is why I had to make its mask a separate model, as otherwise getting it in the right place would be difficult when attached to the end of its hose.
