I think something went wrong during translation or there was a misunderstanding somewhere:

FaceRig does NOT rig the models for you, you / the creator needs to rig the model in a specific way so that FaceRig can use the model. What facerig can "export" are movies made with FaceRig, either live (broadcasting) or recorded.

Also, in the, not yet released, Studio version of FaceRig, it is probably going to be possible to export the animation points, so that you can use those in other programs with models there.

Question though: what made you think / where did you think to read that FaceRig rigs the models for you? That way the devs can improve the text at that spot if it is their own content or ask the creator to correct it / make it more clear.

thanks for the quick reply. I think I somehow mixed that up because I never saw screencaps from inside the program and thought that this is some kind of autorigger (like mixamo) for faces.

But the software still looks interesting to me :)
