Hi...
First go into Preferences (CTRL+P) in both iClone and Character Creator and make sure your "Real-time Render Options" are exactly the same, especially the "Max Texture Size".
If you still notice a difference, then it will likely be down to different lighting and scene settings. To resolve this just save a copy of your CC3 project to say your Desktop or Documents folder and then change the project file extension from .ccProject to .iProject. Now open this project in iClone and you should now get the exact same look.
