ZBrush Tip: ZBrush Base Color Setup for Polypaint Workflows

Establishing a base color is one of the fastest ways to improve the readability of a ZBrush sculpt before adding detailed Polypaint. A uniform fill removes the distraction of the default material color and gives you a controlled foundation for skin, fabric, armor, or creature surfaces.

To fill the active SubTool with a base color:

• Select the SubTool you want to paint.
• Choose a material that makes the forms easy to evaluate.
• Open the Color picker and select the desired base color.
• Enable RGB at the top of the interface.
• Set RGB Intensity to 100 for an exact fill.
• Turn off ZAdd or ZSub so the operation affects color rather than sculpture depth.
• Choose Color > FillObject.

The color is stored as Polypaint on the vertices of the active SubTool. Unlike texture painting, no UV coordinates are required. A uniform base fill works on meshes of any density, although later painted details will need enough polygons to produce clean results.

Choose the correct paint mode before filling:

• RGB fills the model with color while leaving its material assignment unchanged.
• M fills only the material information.
• MRGB fills both color and material.

For most production workflows, use RGB. This lets you switch MatCaps or standard materials later without overwriting the color foundation. Use MRGB only when a particular material must remain embedded in the SubTool’s appearance.

If the chosen color does not appear, confirm that Polypaint display is enabled through Tool > Polypaint > Colorize. Also check that an existing texture map is not visually overriding the vertex color. Turning the texture off temporarily makes it easier to inspect the Polypaint result.

Remember that FillObject affects only the active SubTool. For a model containing many parts, fill each SubTool separately. This is useful rather than restrictive: skin, clothing, armor, eyes, and accessories can each receive a distinct starting color. Rename and organize SubTools before filling to keep the process predictable.

A practical painting workflow is:

• Fill each major component with a mid-value local color.
• Avoid beginning with pure black, pure white, or fully saturated colors.
• Introduce broad warm and cool variation at low RGB Intensity.
• Use masks to protect completed regions.
• Add fine variation only after the large color relationships are working.

Before experimenting, duplicate the SubTool or save a new project version. Although another fill can replace the base, a backup preserves earlier painting decisions.
