Support for object mirroring, used in LN2, is now available in Integrator 2012 🙂
So one might ask: why isn’t on-the-fly mirroring used for objects like the family table, which have two versions stored in RAM?
The answer is: look at the shadows! These objects are NOT an exact mirrored version of each other due to the sides that are in shade.
This was a superb design in LN2. The only objects mirrored by the engine on-the-fly are those that are not affected by lights/shadows.
