ForestSet is a brand-new helper plugin used to create a multi-purpose 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 of the set is assigned as source geometry. For Surfaces and Splines, all items of 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).
