A new problem has arisen in my path to make a custom character. I import the base mesh FBX into Blender 2.78, make the clothing such as a top, UV unwrap it, transfer the weights from the base FBX's armature, and export the FBX. I made sure the "leaf bones", or whatever wasn't check marked. I import the resulting FBX into Character Creator, and get this error. Why? I only had the "default" blender material on the custom clothing. So, I deleted the material at all on the top, and still the below message shows up. Any help would be appreciated.
