I optimised and enhanced the Classroom scene that was provided by face to test the Octane4Soft plugin and because it's christmas time I thought it would be a good idea to share this scene:

The scene was created with Softimage 2013 SP1 and Octane plugin 1.01.
I merged many objects reducing the total number of objects drastically. Now it starts to render much faster. As soon as the plugin supports instances, all the chairs can be instances which will improve performance even further.
Have fun
