Voxel Tools

When you’re in the Sculpt Room, and a Layer in the VoxTree is in Voxel mode,  the Voxel Tools are located on the left-side tool panel. You can also obtain access all of the tools with the Quick Access panel with a tap of the SPACE on your keyboard. Let’s take a look at all of these tools.

Grow

Increases or decreases the surface beneath the cursor. Brush alphas have no effect with this tool. Stroke to sculpt. On the Top Bar the Growth Power slider controls the intensity of the expansion and the Thaw Power slider controls the intensity of the contraction. While stroking, this tool also smooths the area of your brush. Related to the Build and Airbrush tools.

Smooth

A dedicated tool for smoothing any irregular areas of a sculpture.

Fill

Fills cavities that you stroke. It’s useful when you want to make cavities shallower, but not fully level with the rest of the surface. It sometimes requires very high intensity settings to fill areas.

Clay

Blends expansive strokes quickly on the surface of your model. It will also simultaneously smooths the surface after your stroke.

Carve

Places high peaks and deep cavities quickly on your sculpt, while edges of your stroke are not smoothed.

Blob

Creates a continuous cylindrical shape with strokes. Similar to the “2D Paint” tool, but with fewer options, and is entirely freehand without a controlling plane.

Cut Off

Cuts parts of your sculpture using Stroke Mode splines/curves through the entirety of a sculpture.

Airbrush

Constantly grows underneath your brush as you stroke, regardless of stroking motion. Related to the Build and Grow tools.

Build

Grows underneath your brush as your stroke, and only while you stroke. Respects brush Alphas. Related to the Grow and Airbrush tools.

Exrude

Places high peaks and deep cavities quickly on your sculpt, edges of your stroke are smoothed.

Sphere

The size of the sphere is dependent on the size of the brush. When using stylus pressure to control the size, the maximum size will be the current size of the brush. This tool can create volume in the viewport without needing any existing volume by stroking outside of a sculpture (if one even exists). It creates spheres and with continuous strokes can create long, “pill-shaped” cylinders.

2D Paint

This tool creates volume along an axis plane, which you specify by RMB clicking anywhere in space or on the surface of an object. After specifying the plane, any strokes will be created along this plane, regardless of your viewport alignment or any existing sculptures. When you change your view, new strokes will always face the camera. Respects brush Alphas. It also has an important option on the top tool bar: “Double sided”. While activated, this allows you to create on both sides of the plane.

Plane

This tool scrapes volume away from the set position as well as the normal of the brush cursor. You set the brush cursor’s position and normal by clicking and holding the RMB and dragging along the surface of a voxel object. There are five modes by which you decide the position of the brush:

  1. Pick Point & Forward Direction: This will place the cursor at the last location you used the RMB, facing toward the camera.
  2. Pick Point Only: This will place the cursor at the last location you used the RMB only. Its direction is based on the settings in the parameters tab.
  3. Pick Point & Direction: This will place the cursor at the last location you used the RMB, and its direction will be based on the average normals of the voxels that your brush covers.
  4. Pick Point & Direction (Local): This will place the cursor at the last location you used the RMB, and its direction will be based on the single normal of the voxel your brush is centered on.
  5. Navigate: Lets you navigate in the 3D viewport as normal. This can also be done while holding the ALT key.

Scrape

Using brush radius and intensity, this tool scrapes away areas under your brush. Does not respect Alphas.

Pinch

Pinches the area under your brush to create tight peaks and cavities.

Smudge

This tool drags the surface topology along with the brush. It’s great for sculpting wrinkles on a character and drapery.
