If you want a Material/Color to stay in a subtool do the following.
- Select the subtool you want to fill.
- Turn on ‘Mrgb’ button.
- Select the material and color you want to use.
- Go to ‘Color’ menu and click ‘FillObject’.
Now that material and color will stay in that subtool. It only looks like it is in the other subtools because ZBrush is giving you a live preview of the material you have selected. Select another material and see.
Repeat steps 1 to 4 if you want to
‘Fill’ another subtool.
