Thorns on Mesh brush settings

These options appear in the Mesh section of the Paint Effects Brush Settings window, and the Attribute Editor for any brush node.

Large numbers of thorns can be generated off the surfaces of the triangles created when using the MeshBrush Type. These thorns are drawn using the rendering method associated with the ThinLineBrush Type and render quickly. They are single segment tubes, and do not appear in the wireframe representation of the strokes. You can use these to add thorns and prickles to plants or to create furry or fuzzy tubes.

Note: Thorns on Mesh are only created at render time.
