 So, you don't know how to import your face animations to Maya. Not a problem. Export an animated FBX file using your software of choice. Then in Maya, import the face data into your scene. Click the source, open the blend shapes, double click the timeline, and copy all key frames. Then click your face, open your blend shapes, right click, paste connect, you're done. Hope that helps, and as always I hope you have a fantastic day, and I'll see you around.
