Instanced Geometry

Support for Instancing

RenderMan for Maya supports Maya's instancing of geometry. Instanced geometry is a reference to an original geometric master and is particularly efficient, being only a reference to the original object. Using instanced geometry can accelerate Maya's interactive display. Unfortunately, it also has some restrictions, inasmuch as any changes made to the original object affect the instance as well.  

There are several added benefits to using instanced geometry with RenderMan for Maya. Instanced geometry is much more efficiently represented internally in the renderer. A scene rendered using Pixar's RenderMan with fifty folding chairs would be much less efficient than the same scene rendered with one folding chair and forty-nine instances. Instancing geometry can be a very useful technique for optimizing rendering.
