There are two ways to switch off IK on loading:

1. Renaming the leg IK chains
2. Associating a Python script with the .cr2 that executes on load

Poser is hardcoded to switch on IK chains for Left Leg and Right Leg on figure load. I've tried turning off IK in the cr2, but Poser just ignores the .cr2 setting. Only by renaming the chains (to LeftLeg and RightLeg, a small change appears to be enough) I could prevent Poser from automatically turning on IK.

As for not exporting other body part, it is possible. Would be a nice addition to the script. I'd have to create a CR2 Writer object, but it can inherit a lot of stuff from the PZ2Writer object. I'll keep it in mind.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
