A2F not showing character's material & character transfer not working


I have followed this tutorial on how to export CC4 characters into A2F. I did the export exactly like in the video, but after I place my character on the scene the material is gone. Also, I have tried to do the character transfer with it and it doesn’t work at all, only the default character speaks.
I am new to omniverse too, and not sure if I am doing something wrong with the usd. I’d love to know if there is a way to fix it.
