Sculpt Tools tray

The following default tools appear on the Sculpt Tools tray:

TipQuickly select items in Mudbox trays using the number keys on your keyboard. Pressing keys 1 through 9 selects the corresponding tool position in the active tool tray. Middle-drag your frequently used tools to the first nine positions on a tray.

Tool Name	Icon	Purpose
Sculpt		Builds up initial forms and moves vertices in a direction determined by the average of all normals within the boundary of the tool cursor. Use the Direction property to modify the default setting (for example, Camera, X, Y, Z and so on).
Smooth		Levels vertex positions in relation to each other by averaging the positions of vertices.
Grab		Selects and moves vertices based on the distance and the direction you drag. Useful for making subtle adjustments to the form of the model. Modify the Direction property to constrain the movement of the tool. For example, XY constrains vertex movement in the XY plane.
Pinch		Pulls vertices in towards the center of the tool cursor. Useful for more sharply defining an existing crease.
Flatten		Levels affected vertices by moving them toward a common plane. Useful for designing and detailing.
Foamy		Similar to the Sculpt tool but with a softer feel. Useful for designing initial forms, not intended for detail work.
Spray		Used mainly for detailing surfaces, intended for use with stamps. The image is stamped along the stroke in a random fashion. (Uses a stamp image by default.)
Repeat		Useful for creating patterns on a surface. For example, rivets on the wing of an airplane, zipper effects, stitches on cloth, and so on. (Uses a stamp image by default.)
Imprint		Presses or imprints a stamp image into the surface. Dragging on the mesh positions and scales the stamp.
Wax		Builds up areas on a model, adding or removing material from the model surface, much like working with clay or wax.
Scrape		Useful for minimizing or removing protruding features. Quickly calculates a plane (based on the vertex positions wherever the cursor is first placed) then flattening any vertices above the plane.
Fill		Fills in cavities on the model surface by calculating a plane (based on the average of the vertices within the tool cursor), then pulling vertices under the plane towards that plane.
Knife		Cuts fine strokes into a surface. (Uses a stamp image by default.)
Smear		Moves vertices in a direction that is tangent to their original position on the surface in the direction you stroke.
Bulge		Displaces the region beneath the tool by moving each affected vertex along its own normal to create a bulge effect.
Amplify		Opposite of the Flatten tool. Useful for designing, detailing, and further accentuating existing differences in the affected vertices in relation to each other by moving them away from a common plane.
Freeze		Locks affected vertices so they cannot be modified while you sculpt. You can freeze vertices on the base subdivision level as well as on sculpt layers. By default, frozen faces appear blue. For more information, see Mask or freeze regions on a model.
Erase		Removes sculpting from layers. Any sculpting on the original base mesh remains unaffected. See Erase sculpting on a layer.
Mask		Lets you paint opacity values on sculpted regions to non-destructively hide the sculpting on a layer. Works only on sculpt layers, not on the base subdivision level for the model. Each sculpt layer can have its own mask. The Mask tool can also be useful for cleaning up artifacts resulting from scan data or map extractions subsequently applied as displacement maps.
