I've never run into this problem b4. For some reason when i import my model into CC4 the Normals are displaying inccorectly. I exported them from Substance Painter in multiple versions and none worked.
Why is this happening?

After Further Investigation, it appears this only happens to 8K texture maps. This leads me to believe CC4 and iClone are unable to handle resolutions above 4K. 

Did you try adjusting the Max Texture Size under Real-time Render Options in Preference? It goes all the way up to 16k.

Thanks for the feedback, For some reason when I export textures from substance, iclone and CC4 only seem to like Vray normals. Not sure why but it works
