In an effort to eliminate occlusion of the 3 IR markers on the hand, I attempted to add a few more IR markers to the existing wrist tracker skeleton. I then redefined the "hand" rigid body in Motive to include the existing 3 markers plus the ones I added. Motive handles this very well. The software only needs to see 3 of the total number of markers in order to track the rigid body through space once you change a setting in the body's advanced options (Rigid Bodies -> Rigid Body Settings -> Advanced -> Min Marker Count = 3). The added markers help (at least somewhat) prevent obstructions from compromising wrist tracking in Motive. However, when I tried to load MuJoCo with the project.tpp file with the novel hand trackers, I got an error while loading MuJoCo saying "Expected 3 markers per body," and I cannot track anything in the VRE thereafter. Would it be possible to remove this limitation and allow more markers per body? Removing this limitation for the wrist is the most important since the wrist markers are the most likely ones to become occluded. Furthermore, this tracker has the most control over the virtual hand, and therefore a person's control of objects in the VRE. I see adding this feature as a good way to improve the VRE's interface, assuming the VRE's handling of extra markers won't sacrifice too much processing power.
