Some of the entries in Renderotica would bring to some the need to get chains right. The movement of each link against the next is complicated, but if the chain is vertical, an approximation would be for it to have one rotation center when xrot'ing and another rotation center when zrot'ing. Poser (at least Poser 3) 's joint parameter window is set up as if only one center can be defined per joint. But if I look in a .CR2 file, each segment has 3 places for specifying centers: one each in that segment's 3 channels twistY, jointX, jointZ. What would happen if I text-edited the .CR2 file to have these 3 centers not all the same in the same segment? Obeyed, ignored, or would it make Poser malfunction badly? Would it be preserved if I loaded and saved the model?
