I have Poser 4.0.3 without PPP. When I was working on a new version of my USA army flamethrower (see the thread at this link), I got yet another harassment of the persistent IK bugs. This bug causes inaccurate or completely wrong conversion of the rotates and translates of an IK-goal between (coordinates relative to its IK-parent) and (coordinates relative to its ordinary parent) as I switch that IK-chain on and off. To that add the results of Poser getting confused between the two different coordinate sets that all the members of an IK-chain have, when that IK-chain is on:- (1) The translates and rotates as specified in the channels. (2) What those translates and rotates must be changed to to make the ends of the IK-loop meet; organic chemists call the effect "ring strain". In one case, as I switched a man's between IK-on and IK-off repeatedly, each time I switched it on, the hand moved but the arm stayed still; and whenever I switched it off, the hand stayed still and the arm moved to keep up with the hand. hen i did this with the fuel hose, which is an IK-chain of several segments, the gun went into a completely wrong attitude. This is making it impssible for me to provide poses to set up a Poser person wearing that flamethrower himself; and I have had similar often with my scuba gear models.
