Quote - I dont think it would be fair to allow people to add objects to the scene, only because the quality of the objects available for each person depends either on their library, or there other application and skills in modelling. Not everyone has the same library and modelling applications.

I take this to mean then that no human figures will also be allowed right?  (had to ask because this is Poser after all) Because the same things apply, some may have just default figures and others more realistic hair, clothes, etc?  So just to clarify, this will be a render of the scene as you set it up but we can change the lights, textures, materials and add environment or an environment sphere.  And all renders will be with the same camera settings and show the exact same thing from the same perspective, right?
