Hi, I am always facing normal problem with character creator export. It shows hard seams in edges of UV and some weird black spots on the model as well. 
I found the same issue here, https://forum.reallusion.com/323008/Character-Creator-to-Max-Normal-Map-Seam-Problem  , but it did not fix my problem. I have tried loading the model, textures in max, maya, all shows the same problems. Is this a software bug or only me facing this issue? The only way we fix it is to make a new normal texture in zbrush.
