Diffuse and Range Maps

The Diffuse map in ZBrush Face Tools is converted from your character model’s head diffuse map in CC. Enabling the Diffuse option enhances the visual accuracy of your character in the ZBrush viewport and provides a better visual representation when editing your model in both the base mesh and expression layers.

To transform your Diffuse map in ZBrush into polypaint for your base mode for further editing, follow these steps below.

2. Activate the Mrgb option in the top control bar.
   
3. Navigate to Tool > Polypaint and select Polypaint From Texture.
   
4. Disable the Diffuse option in Texture and examine the polypaint applied from the diffuse map.

• For guidance on polypainting in ZBrush, please visit this page.
• It is recommended to avoid using the texture map options with models that already have polypaints, as this can result in an inaccurate visual representation. For further details, please consult the FAQ page.

When editing the facial expression wrinkles, it is helpful to understand the effective boundaries of each expression. Enabling the Range map reveals the regions of expression, helping you avoid unnecessary edits outside of these areas.
