I was faced with the following problem recently. I had posed a V3 figure on a vehicle character (the DAZ Skybike), and wanted to turn the handlebars of the bike. This meant that I had to extensively rework the pose to keep her hands on the handlebars. What I wanted to do was to somehow keep her hands attached to the handlebars, her feet to the pedals, and her butt to the seat. I could use IK, but my understanding is that IK attempts to anchor the feet and/or hands to fixed positions in space, not to objects.

Is it possible (in the joint editor maybe) to extend the IK chains to include parts of the bike? In this case, I probably have things easy because the front (including handlebars) and the footrests are all body parts of the bike. If the vehicle was a prop vehicle, an IK approach might not work as well.

Any suggestions?
thanks
