When I import the texture of my character from Roblox Studio to Blender (using the PaintRigV3) everything but the head and a leg turns black. I have tried changing the avatar and have tried different versions of Blender but nothing has worked.
Try different textures. Sometimes they have the same file name except for the number at the end.
make sure you import a character which is R6
Try R6 and try the blocky body on your avatar, there are also women body rigs if you don’t want the blocky body.
