I've done a bit of generating and modifying poser characters in rhino, with a bit of parenting. Here is a distorted tube...I don't know where along the poser-rhino-compose-truespace(for a bit of boolean mesh editing)-compose-poser workflow the problem is caused, but any advice would be appreciated. The poser man(low) head is the parent of the big bluegreen helmet prop, and the big bluegreen helmet prop is the parent of the air hose, which is the goal of an ik chain in the figure made up by the hoses and air tanks. long sentence, I hope it made sense. Thanks in advance. dan in nyc
