This 3-part video series covers the topic of Tracking using Exclusive Constraints. This is when foreground detail gets in the way of a 3D or Planar Track and foreground objects need to be excluded. In part 2, we redo the 3D track again however we don’t use the matte for this workflow. Instead we look at using a Gmask Shape as an exclusive constraint for the 3D track. Note that the workflows are different depending whether you use a media matte or Gmask shape with a 3D track.
