NOTE: Make sure the LEDs of the foot markers have approximately the same
distance from the floor and the hand markers approximately the same distance from
the wrists; otherwise you will have trouble capturing the T-pose later on.

PPT MOCAP - SETTINGS TAB
The "
Settings " tab lets you choose model presets and the orientation source. Each
model preset represents a set of heuristic settings. The following presets exist:
 Hard L/R separation: Separates left and right depending on the body axis. The
advantage of this preset is that it does not swap markers. The disadvantage is
that it will produce incorrect results if the arms or the feet are crossed, if the
arms are lifted above the head, or if the arms are further back than the hip
marker.
 Default: Compared to "Hard L/R separation" this preset has no movement
restrictions. The downside however is that if the markers are confused, they
will stay swapped until the reset T-pose is detected or until the distance
between the swapped markers is close enough to swap them back.
 Good Tracking: This preset makes it even harder than the "Default" preset to
swap markers by bringing them close together. This preset is recommended if
you have good tracking quality that does not rely so much on the Mocap plugin
to resolve mismatched markers.
 User defined: This preset just appears if you altered the heuristic settings in
the advanced tab manually.
The orientation source only needs to be adjusted if the hip marker is set to "Fake" or
to "Pos". Choose whether you want the hip orientation based on the head
orientation, the feet orientation, or a blend of both orientations. Use the head
orientation for walking motions (you keep your head most likely aligned with your
torso). Use the feet orientation for standing motions (you can turn your head
independently from your body as your hips is stiff as long as your feet do not move).
