In the renderer's implementation, a single representation of the geometry is designated as the master. This master geometry representation includes all the relevant geometric details (vertices, faces, primitive variables, etc) as well as all attributes including material (Bxdf) and light bindings. Multiple instances of this master can then be created. Each instance is allowed to have its own transformation, but is otherwise an identical clone from the master, except for some attributes that can be overridden to allow for a limited amount of shading variation. The renderer will reuse most of the memory associated with the master with each instance, although there remains a certain amount of unavoidable overhead associated with each instance in order to store the transformation and the limited number of attributes that can be overridden.

You should set a Dice Instance Strategy on instances can alter the Dicing Strategy on Instances by applying the attribute but it is not required to render them. |
