[Bf-cycles] rendering instances in Cycles

[Sergey Sharybin]

In your example is rather correct, it'll create two objects which are
sharing the same mesh. ObjectManager and BVH builder detects if objects are
sharing the same mesh and does some special things for proper instancing
then.

Not sure why do you ask about shaders, they are not object property,
they're mesh property. Synchronization code from blender/ is whet you want
to look into to understand it better.
