Track .R3D in mocha

I have some .R3D files I’m working with in After Effects CC 2017 latest version. When I bring a clip into mocha using Animation>Track in mocha AE it does not load into mocha, it just starts a new project. If I try to import the clip directly into mocha it tells me the file is corrupt or unsupported format. I read some of the other forums and topics from the past and I know that .r3d files are supported, so why isn’t it loading?

Graphic drivers up to date, AE up to date. Is there some sort of .r3d codec I need to download and install?

I also tried to compress to a quicktime animation and that now loads into mocha but its completely distorted. What is going on?

Also tried an avi. Does the same thing as .r3d files.

I’m having the same issue. Did you figure it out?
