Ok, I had someone create a 3d character for me in Blender. And I want to import the character to Character Creator to add clothes.

I imported the model to Mixamo to auto rig it. Next, I imported the character to 3Dxchange.
Now, do I convert it to Non-Human or Non-Standard Character?
After this could I be able to import the character to Character Creator? Or am I missing a step?
Thanks
