The PointScatter Meshop
Scatters free floating vertices (semi particles) in any closed mesh volume, on any mesh surface, along any set of curves. It can also distribute points in the shape of a basic tree/bush.
The SPCOperator Meshop
Grows curves in different ways to mimic the typical structure of different kinds of vegetation based on attractor points (the semi particles).
The SproutPass Meshop
Transforms curve vertices in different ways to mimic growth.
The TwigOperator Meshop
Lets you add additional polylines/curves from the curve tip along any curve towards its start point with lots of control. It also adds particles with transformation control to the curve tips that can be used by replicators to distribute prototype leaves/twigs/billboards to its positions.
The CurveMesher Meshop
Generates a mesh along any set of curves in a mesh layer with lots of control to detail and UV mapping. What is unique with this mop compared to other similar curve mesher tools in Modo is its ability to understand curves that are attached to each other based on certain rules. It understands the typical structure of a tree.
