Retouch setups originating from versions of Smoke earlier than 4.0 are not compatible.
Tracker setups from pre-4.0 versions can be loaded in the Smoke Stabilizer if you change each instance of “tracker” in the setup file names to “stabilizer”. For example, if you have a Tracker setup file and proxy called mysetup.tracker and mysetup.tracker.p, you can change the file extension of these files to mysetup.stabilizer and mysetup.stabilizer.p, respectively, and then load them into the Stabilizer.
