It can be done, but there are currently limitations of how this can be done. For instance, the VariableTag is no longer available so one must use CTrack::FillKey() with the object containing the track having had its points 'changed' to get the PLA data stored.
This code is not identical to the previous code - in that it is used to convert an animated, rigged figure into an animated Polygon object using PLA. So you'll have to make the changes to reflect the inputs and results desired.
