I was able to convert 2K20 Cyberfaces to 2K17 using the 2K18 to 2K17 Method by The Goods and also Mesh Data transfer also by him. The method on transferring the headbands and other parts of the face is from Trevor's Video
For the Hair and Beard I used the Hair Add/Swap tool by Trevor
The only problem will be the beard is not moving with the mouth I dunno if to fix that we have to look at the hihead file or thru Blender. If anyone knows how to make beard move with the mouth please let me know. So a 19-20 roster is Possible. I can also do updated Jerseys. Please if anyone can Help to make updated Roster for 2K17 please comment down.
