Insert Brushes Combined with Curve Strokes
Any Insert brush (including the InsertMultiMesh brush) can be combined with Curve Mode in the Stroke Palette. This gives you the ability to drop multiple instances of the mesh along the curve.
This feature gives you a variety of new possibilities when sculpting. For example, you can create real geometry such as a series of bolts or chain links along a model instead of using an alpha to sculpt them.
To create an Insert mesh brush that supports curves or modify one that already has this support, you need only to enable the Curve mode located in the Stroke palette. Once that has been done, creating a stroke will duplicate the mesh along the curve. It will do this in accordance with the Curve mode settings and of course, the Brush modifiers.
To define the distance between each inserted mesh, use the Stroke >> Curve Step slider. A value of 1 will touch each inserted mesh to its predecessor. Lower values will cause the inserted meshes to overlap while higher values will separate them from each other.
If you are happy with your curve, but it drew the wrong mesh you only need to swap out the mesh in the Brush >> Modifier >> mesh Insert Preview. Now click once on the already active curve to replace the original mesh with the new selected mesh.
Keep in mind that InsertMultiMesh may also be a solution for you, depending on your needs.
If the (M)RGB mode is enabled, the current PolyPainting value will colorize the inserted mesh based on the RGB Intensity slider, partially or totally overriding the RGB color.
If the Gradient mode is enabled, the RGB color will be progressively following the curve between the start and end point.
