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.

Editor¶

The Brush node editor is where the sculpting happens.

Drag with LMB	to edit the model
[ or ]	to change the brush size
Drag with RMB	to change the brush size
SHIFT + [ or ]	to change falloff
Drag with SHIFT + RMB	to change falloff
Drag with MMB	to change strength
Hold SHIFT	to temporary switch current brush to the Relax brush
Hold CTRL	to invert normal directions for brushes
Hold A	to hide the editable model
Hold Z	to show the source model plugged to the third input of the node

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

Tip

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

Brush Types¶

Relax Brush: smooths the mesh based on the average position of adjacent vertices
Move Brush: moves the mesh vertices
Sculpt Brush: moves the vertices along the mesh normal
Inflate Brush: moves the vertices along their normals
Project Brush: projects the vertices to the reference mesh
Relax-Project Brush: is a combination of the Relax and the Project brushes
Move-Project Brush: is a combination of the Move and the Project brushes
Clone Brush: copies and pastes local surface features from the source geometry to the editable mesh

Inputs¶

geometry: Geometry Geometry to be edited with brush
reference: Geometry (optional) Geometry to project the edited vertices to
geometry source: Geometry (optional) Geometry that is used as a source for the Copy brush
vertex mask: VertexMask (optional) Vertex mask to bound brush influence

Output¶

Geometry Edited geometry

Parameters¶

Apply

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

Reset

discard all the changes

Brush type

selects the brush type

Radius

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.

Strength

brush strength

Falloff

changes the shape of the intensity curve

Projection Dist

Brush size: projection distance is equal to the current brush radius
Custom: 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)

Note

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
Opacity: 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.
