Hey Eric,
Nothing has changed... you can paste Mocha AE data back to AE 2 ways. Select the Mocha layer and go to export shape, then copy to clipboard.Â
In AE you can do Paste>mocha mask. This converts Mocha AE shape to an AE mask.Â
Or you can do Paste which should apply the free Mocha Shape effect. This uses a plug-in to generate the mask and the per-point edge feathering found in Mocha AE will translate.Â
Hope this helps. I do know that in various iterations in the past (on PC), the Adobe clipboard would sometimes get wonky. I remember having to copy to clipboard, hide AE and click on desktop, then go back to AE to paste.Â
Lastly, if you are using Mocha Pro plug-in, this process is greatly simplified as you can select "create AE masks" in the plug-in and it will automatically convert the Mocha shapes to AE masks. And Mocha Pro 5 can convert Mocha spahes to Premiere as well. ;)Â
