Any garbage mattes that you set up using the SynthEyes Roto panel will occlude (cause holes in) all planar trackers that they pass in front of. So you can set up an animated garbage rotospline around actors, vehicles, elements of the set, etc that pass between the camera and the tracked 3-D plane. Be sure to set the spline to "Garbage" on the roto panel, not "Camera01", "Object01", or other camera or moving-object names: only garbage mattes are processed by planar trackers.
Note : Roto-masks are quite different than In-plane masks. Roto masks are animated, correspond to something that is not part of the planar surface, are not specific to any particular planar tracker, and are created from the SynthEyes Roto Panel. In-Plane masks are static, correspond to something on the planar surface itself, are part of a particular planar tracker, and are created using controls on the Planar tracking panel.
Warning : The “Invert” button on the Roto Masking panel is not supported by Planar Tracking. Inverted layers are treated as if they are not inverted. In all known cases, a spline stack containing inversion can be converted to an equivalent version that does not use inversion (and it’s usually simpler).
You can create some preliminary conventional or 2-D planar trackers and use the "Import Tracker to CP" (control point) button on the roto panel to rapidly animate a spline. Import to a spline's Origin and Rotate/Scale control points to rapidly create a spline that tracks something through an entire shot. Once you've done that, you can hand-animate the individual control points for fine tuning.
