This palette of tools is an abbreviated version of the sculpting tools found, in their entirety, in the Surface Mode Surface Mode section of the Voxel Room.

Surface tools are modifying surface vertices instead of volume. This approach works much faster than voxel-based sculpting. But modification of the surface leads to polygon stretching, so if you feel that the surface is stretched too much press ENTER to apply changes and transform surface back to voxels. In general we recommend that you click the letter “V” icon in the VoxTree and get to Surface mode (letter “S” icon). There is a much more powerful tool set for surface style modifications. See the Surface Mode descriptions in that section.

Surface mode is much faster for sculpting than the regular volume mode. Only the surface mode tools will be available while editing in this mode, plus with the Pose, Move and Transform tools. Some of the surface tools have counter-parts from the volume sculpting tools.
There are a number of unique tools in this mode as well, which we shall discuss below:

Draw: The draw tool is great for sculpting horns, or anything else like that very quickly. It is very much like the airbrush tool, however it only operates on the surface of a volumetric object. Use LMB to raise the area beneath the cursor. CTRL+LMB indents the surface, and SHIFT+LMB smooths the geometry.
Pinch: This is very great for making very nice tight edges, cavities and peaks. You can better see that on the pictures below. It is identical to the Vox Pinch tool, however it only operations on the surface of a volumetric object. This option draws the surface area closer to the radial center of the cursor. Use CTRL to expand the surface outward from the center of the cursor.
Shift: This tool slides/drag geometric points of surface topology along the stroking motion relative to screen space with the brush. It’s great for producing wrinkles and so on the character or a creature or for making cloth. It is identical to the Vox Follow tool, however it only operations on the surface of a volumetric object.
Flatten: This mode flattens the surface beneath the cursor by raising or lowering points to a common plane based on brush size and intensity. Height and angle are averaged from the point directly beneath the center of the cursor, and the effect is expanded to fill the entire cursor area.
Chisel: It works like scrape but dives into surface slightly. It is very handy for creating sharp edges. Use CTRL for inverse action.
Clay: Flatten surface and extrude using alpha, stencil and Smart Material.
Buildup: Behaves like the “Clay” tool, but builds the surface up without limits (not only one layer as with clay).
Fill: Fill cavities. Use CTRL to invert the action - to eliminate “embossing”.
Lute: This tool allows to fill cavities as if you are working with lute. Start to fill with lower pressure and end up with bigger one to get accurate result. Combine this tool with smoothing to get perfect result.
Expand: Extrude surface along vertex normal direction.
Extrude: Extrude surface. Gum: Extrude surface using alpha, stencil and Smart Material. It works well with cube mapping to make skin, pores or wrinkles.
Absolute: Absolute extrusion - relative to initial surface shape.
Rapid: Very quick for rapid shape building.
Rapid2: Smooth version of rapid tool.
Scratches: Draw scratches along the stroke. Scratches will fade existing geometry as clay.
Freeze: Freeze parts of the surface. Use CTRL+D to clear frozen parts, CTRL+SHIFT+I to invert freeze.
