Adjustment Tools

The Adjustment Tools are available to both the Voxel and Surface Sculpting toolsets unless otherwise specified, and appear on the Left Tool Panel. Let’s take a look at the general Adjustment tools.

Cut Off

Cut areas of your sculpt clean off using various Lasso Stroke Modes. Respects Depth Limit in the Stroke Mode panel. Great for creating hard surface sculptures very quickly.


Click and holding with the LMB you can measure from the beginning to the end of your stroke allowing you to more accurately sculpt to scale. Releasing your click will deactivate the measuring tool.


Allows you to visually select and make active a layer in the VoxTree by simply clicking on a sculpt in the 3D viewport. In the event you may have a large scene with many various parts and pieces, this makes it very easy to pick a layer you wish to sculpt by clicking it, rather than attempting to locate it in the VoxTree by name.


This tool is great for quickly changing the rotation, scale and translation of a selection. You can determine the selection in several ways. You can use a gradient with different methods: Line, Ring and Sphere. You can also paint a selection that is brush based or an entire object. You create selections by stroking with your stylus and then releasing the LMB to complete the stroke and create the selection. Using Paint Select mode, you can also manually smooth your selection by stroking while pressing and holding the SHIFT key. This works even if you’ve used another selection mode, simply change your mode to Paint Select and begin stroking in the area you wish to smooth. Let’s take a closer look at each of these different selection methods.

  • Line: Allows you to draw a linear gradient, from the beginning of your stroke, to the end. The beginning of your stroke will be the beginning low value of the selection falloff, and the end will be the maximum value. Thus the end will be affected more by the following transformations.
  • Ring: Creates a linear-like ring selection around your sculpt, with each open end of the ring having no effect when transforming, and the center of the ring being completely effected by transformation.
  • Sphere: Creates a spherical or radial selection falloff, with the start of your stroke being the maximum value and the end being the low value. Thus the center is effected more and the outside the least.
  • Paint Select: Allows you to manually paint a selection falloff based off your brush radius and alpha you are painting with. As mentioned above, this mode also allows you to smooth any previously created selection falloffs, even if it was completed in a different mode. You can also add or subtract from the selection falloff with this mode. To add simply stroke, to remove hold the CTRL and stroke. This mode also has a toggle for using an Airbrush style application which allows gradual building of the selection falloff, rather than painting it. Lastly, this mode also allows for the use of nearly any Stroke Mode from the Stroke Mode panel, for a wide amount of variety in stroking selection falloffs.
  • Object: Allows you to select and effect an entire layer in the VoxTree by clicking on the object in the 3D viewport.

After a selection is made, the Pose tools transform gizmo will become active. The Pose tool has three different transform gizmos. The first is a multiple ringed gizmo with arrows and cubes. This allows you a standard all-purposed transform gizmo for translating, rotation and scaling your selection. The second is a “Rod” style transform gizmo, which allows you to transform along the “rod”, using translation, rotation and scaling. The third and last gizmo, is a free form cube, which encircles your selection falloff.



Click and drag with the LMB to move the underlying effected area of your brush, relative to the screen view. Hold CTRL to move the area along the average surface normals. The Move tool also respects brush Alphas.


This tool lets you rotate, scale and translate your currently selected layer in the VoxTree. By grabbing one of the gizmo handles you can constrain to whatever axis you clicked. You can also perform a screenbased rotation using the large outer ring. Let’s look at the options for this tool.

  • Move Only Gizmo: Lets you make adjustments exclusively to the gizmo. This helps when you need to place the gizmo in another location.
  • Leave Rotated Axis: This is great for when you need to rotate an object multiple times while retaining its previous rotations.
  • Position & Axes (1,2 & 3): These parameters let you manually key in the position and rotational coordinates.
  • Scale (X, Y & Z): These parameters allow you the manually key in scalar modulations.
  • Reset Axis/Space: These two functions let you reset an object’s axis or local space.


Creates instances of a Vox Layer you specify. You can clone an instance from the RMB Menu and merge new objects as instances. Negative volumes can also be instances. Instances also consume less RAM and can help improve scene performance in heavy scenes.


This looks at the existing volume of an object, and extrudes to create new volume based on the position of the gizmo. A helpful tool for creating jewelry.


Voxel Specific

Some of the adjustment tools are only available when a Vox layer is in Voxel mode. Let’s explore those tools.


Allows you to paint the areas you wish to hide. This tool respects other Stroke Modes. Can be used to easily create hard edged surfaces for objects. The tool also has a few other functions, which you will find in the Voxel menu. Such as invert, unhide, delete hidden, seperate hidden, etc..


Hide polygons of the sculpture with a brush stroke or other Stroke Modes. If any sculpting is done, it will not performed on the hidden areas.


To use this you must have two Layers in the Vox Tree It is preferable if one of the Layers is empty, but it doesn’t need to be. With this layer selected and another layer in the background with a sculpt in it, you can stroke alone the background objects surface to copy only the brushed portioned to the selected layer.


This tool twists and bends the currently selected object layer in the VoxTree. Note: Each function of the Warp Types will alter any of the other type’s end functions. Experimentation is strongly encouraged. There are two Warp types, Bend and Twist. Bend will bend or wrap the current layer around the base of the gizmo.


Bend will bend or wrap the current layer around the base of the gizmo.

  • Segments count: Increases the number of segments.
  • Forward Step: Create a helix.
  • Step Scale: The distance between steps in the helix.
  • Overlap: This tapers each segment where they meet. The effect will vary depending on the object.


Twist will rotate the current layer around its pole.

  • Segments count: Increases the amount of segments.
  • Twist angle: Twists the current object around the gizmo.
  • Overlap: Tapers each segment where they meet each other, simultaneously increasing/decreasing the space between each spiral.


Duplicates and rotates a Vox layer from a central axis. Use Axial Symmetry Order to determine the total number of copies. You can merge these copies as separate instances if you desire.

Surface Specific

Some of the adjustment tools are only available when a Vox layer is in Surface mode. Let’s explore those tools.

Close Holes

Allows you to select and close holes in a polygonal mesh.


Allows you to generate procedural noise on an entire Vox layer or a masked selection.

Quick Pose

Start with painting a mask on your sculpture. Use Contract or Expand to increase or decrease the area to be affected (hit Modify to apply the contraction or expansion). Once you’re complete with your mask, hit Apply and the tool will switch to a brush based Move tool which you can use to sculpt your previously created mask.

Fill Holes

Fills holes in mesh, with the option to adopt the contours of the surrounding mesh.

Poly Remove

Paint an area with a mask on your sculpture to completely delete the affected polygons in the masked area.


Quickly remesh a local area by painting a selection and then applying it. The Detail parameter controls the amount of geometry that is created during the remeshing process.


Allows you to connect two holes together to by forming geometry between them. Let’s look a the options for this tool.

Arch: Controls the curvature of the bridge. A value of 0 will create a linear bridge, higher values will start bending and twisting the bridge.

Smoothness: Smooths the geometry of the bridge.

Clear Selection: Clears your edge selection of the hole.

Apply: Creates the bridge.

Cut: When turned on, deletes the polygons you painted selected for the bridge. When off, the polygons remain even after the bridge.

Split Factor: Allows you to specify the amount of geometry of the bridge. A value of 1 will allow 3DCoat to automatically determine the need geometry. A lower value will have less geometry, and a higher value will have more geometry.

Modify Selection: Expand allows you to enlarge the selection area and Contract reduces the selection area.

Modify: Applies the Expand/Contract modification.
