NodeIcon Brush

Provides a set of brushes to sculpt and cleanup meshes.

All the brushes only modify vertices and normals leaving the topology unchanged. The Brush node can be very useful for correcting mesh artifacts after wrapping.


The Brush node editor is where the sculpting happens.

On the left of the editor, there is a palette of all the available brushes.


Use 1 - 8 keys to quickly switch between the brushes.


Brush Types

Relax Relax Brush:

smooths the mesh based on the average position of adjacent vertices

Move Move Brush:

moves the mesh vertices

Sculpt Sculpt Brush:

moves the vertices along the mesh normal

Inflate Inflate Brush:

moves the vertices along their normals

Project Project Brush:

projects the vertices to the reference mesh

RelaxProj Relax-Project Brush:

is a combination of the Relax and the Project brushes

MoveProj Move-Project Brush:

is a combination of the Move and the Project brushes

Clone Clone Brush:

copies and pastes local surface features from the source geometry to the editable mesh

applies changes made with a brush to the node output. Shortcut Ctrl + Return.


discard all the changes.

Brush type:

selects the brush type.


brush radius is computed relatively to the size of the editable model, and specified in the range between 0 and 100. 0 corresponds to the Min Size Factor and 100 corresponds to the Max Size Factor. Both factors are defined as a fraction of the diagonal length of the bounding box of the editable model.


brush strength.


changes the shape of the intensity curve.

Projection Dist:
Brush size

projection distance is equal to the current brush radius.


projection distance is explicitly specified with the Custom Projection Dist parameter.

Custom Projection Dist:

projection distance in centimeters. Only used when Projection Dist is set to Custom.

Use Geodesic Distance:

the influence of the brush to a vertex is proportional to the distance from the vertex to the brush center. If Use Geodesic Distance is set, the distance is computed geodesically on the mesh surface. If not set, the distance is computed as a distance in space (Euclidean distance).


Use Geodesic Distance option is only available for meshes with manifold topology

Use Opacity:

if set, the editable geometry is displayed as a semi-transparent overlay. The opacity of the overlay is defined by the Opacity parameter. Shortcut D.

Include Backfaces:

if set, geom backfaces can be targeted. Shortcut B.


opacity of the editable geometry. Only applied when the Use Opacity parameter is set.

Min Size Factor:

defines the minimal brush Radius.

Max Size Factor:

defines the maximal brush Radius.

Mask color:

foreground color for the vertex mask to be mixed with background color, which is taken from the Color parameter in the LoadGeom to the corresponding model.
