I hope this is not a RTFM-issue, because then I'd need to rtfm…
I wonder if it is possible to have MochaPlus to be started out of AE. Right now I choose 'Track in MochaAE' and sure enough MochaAE starts with the clip loaded. I then quit out of MochaAE, save the project and re-open it in MochaPlus, do my tracking and send the data back to AE. Can the MochaAE steps be avoided somehow?
