Sculpt Mode

Unless you're doing a monochrome masterpiece, you need color to work with. Pick a color and then the shape, fleck, or tool that you want to use.

Pick from the presets, or create your own using the color picker and save it for future use. Each group has a ready-made tumbler color.

Those are the ones with sections of different shades. They behave differently depending on the tool used, but also on whether they are static or spinning.

For example, with smear shape, a static tumbler will change with each separate smear, but a spinning tumbler will change dynamically as you smear.
