Use this to paint multiple strokes randomly on a NURBS or polygonal surface. The random settings are based on the options specified below. For more information, see Automatically paint multiple strokes on a surface.
In the
Modeling menu set, select
Generate > Auto Paint > Paint Random > 
to open the
Auto Paint Random window, which provides the following options:
- Spans U, Spans V
-
Sets the number of lines to draw in U and V to define the grid.
- Random Offset
-
Set a value to randomize the offset for the stroke from the grid center. A value of 1.0 makes the offset totally random within the grid.
- Stroke Length
-
Set the length of the strokes relative to the grid. A value of 1.0 is the size of a grid cell.
- Sample Density
-
Sets the Sample Density attribute of the created strokes. Higher values result in smoother strokes and a greater tube density. For more information see Modify stroke settings for existing strokes.
- Surface Offset Min, Max
-
Sets a range of Surface Offset values. The Surface Offset for created strokes is randomized between these values. You could use this, for example, to create a cloud of strokes about a surface. For details on Surface Offset, see Set up to paint in 3D.
- Clip Edges
-
Turn this option on to clip the strokes to the surface. When this option is off, the strokes can go outside the boundaries of the grid.
- Equalization
-
Modulates the Sample Density for the created strokes based on the length of the stroke path curves (curves on surface). This helps keep tubes more evenly distributed.
- Share One Brush
-
Turn this option on to make all strokes share one brush. When this brush is off, a separate brush is created for each stroke. For information on brush sharing, see Make strokes share or unshare the same brush.
