- In CC, import or open your CC3+ (or later) character project.
- Go to Modify > Expression Wrinkles > General setting and enable Activate Expression Wrinkles.
At the Texture Settings section, make sure the diffuse maps are all set to Individualize, this setting will yield better facial details and accurate polypaint results.
- Go to the top Toolbar and click Face Tools.
- The ZBrush Face Tools dialog box will appear.
- For the Action field, opt for Create New if this character model is being dispatched to ZBrush for the first time.
- Under Include, deactivate the Normal Detail option.

- Click the GoZ button near the bottom of the dialog box to send your character to ZBrush.
