momodot - If the scene is put into box-tracking mode, it usually takes a minute or two to do a run. In the other tracking modes the run can take quite a bit longer.

lucstef - There is another sphere prop that is placed in the scene when setting up for a pose. The Base is used at the beginning of a run to calculate a maximum distance from the Seeker to the Target. In the case of the above images, the Base is placed in the figure's chest and parented there. It's pretty much a housekeeping issue but gives the script a realistic frame of reference for the distance calculations. The pose that results from a distant Target depends on how the limits on the rotations are set. In the attached Koshini image, the Target was set closer to the sword handle then the left arm could reach. The results still worked well for the pose though. When posing the right arm, the Seeker (the red sphere) was posed onto the sword tip then parented to the right hand. There is a lot of flexability in the script for setting up the relationship between the Target and the Seeker.

maclean - Yes, it's a PoserPython script so should run fine on anything that runs P5 or the ProPack. And yes, you certainly can place the Target on a different figure and have the Seeker track to it. The figure that the Seeker is parented to is just a vehicle for moving the prop. All distance calculations are between the two props and don't involve the figures.
