Instancing is a feature which allows many instances (or copies) of a mesh to be represented in the scene, while only actually storing the mesh once (thereby saving a lot of memory compared to straight-forward duplication).
There are two ways this can be achieved in SkIndigo:
A proxy is a reference object that references a more complex object with a usually simpler copy, in order to keep the overall scene geometry low, while allowing the render geometry to stay high.
- Create the object you wish to copy, create a component out of it (right click, select 'Make Component') and name it “objectname”
- Create a new object to use as a proxy (a cube will do) and create a component out of it named “objectname_dummy”. It is important that it has the name of the original component followed by “_dummy”
- Copy and manipulate these dummies around the scene and on render they will be replaced by the original component.
Copies of components in SketchUp will export using Indigo instances.
- Create the object you wish to copy, create a component out of it (right click, select 'Make Component'), with any name
- Copy and paste the component object.
Component copies will be exported as Indigo instances - each component copy will only use a small amount of memory.
