ForestSet Plugin


ForestSet is a brand-new helper plugin used to create a multipurpose container for scene objects. A ForestSet object can be added to a Forest object as a collection of geometry, surfaces, references, or areas. Multiple Forest Objects can share a Forest Set, making it simple to add or remove areas, geometry, or surfaces and update several scatters from one easy-to-edit location. Even better, the contents of a layer can be dynamically linked to a Forest Set, making it easy to update scatters using familiar scene organisation tools.

Forest Sets can be used in Forest Pack nearly anywhere you can add scene items, including

  • Spline Areas (Include or Exclude)
  • Object Areas (Exclude)
  • Surface Areas
  • Scatter Items (including non-geometric objects)
  • References in Distribution > Reference mode
  • Paths in Distribution > Path mode
  • Particle Flows in Distribution > Particle Mode

Depending on where they are used, Forest Set's may work a little differently as follows:

  • For Geometry, a random item if the set is assigned as source geometry. For Surfaces and Splines, all items if the set are used as input.
  • ForestSet accepts any scene object as input, but only compatible types are used in each case. For example, a Spline cannot be used as a surface.

Also, there are a couple of other considerations to be aware of:

  • Groups, ForestLOD and Forest objects are not supported as items at present
  • ForestSet supports nesting (using a ForestSet within another ForestSet).
