In the same realm of thought, does Poser 9 or 2012 support the use of IES profiles on light sources?  I know we have inverse square falloff for realistic decay, but the use of external IES profiles, especially on mesh lights, or material lights, helps tremendously to improve realism by duplicating not only decay by power, but also photometric web representation of different real-world light bulbs and fixtures.  For interior lighting, this plays a big role in arch/viz accuracy, and overall interaction with materials in the scene.  In other words, it "looks more real" than just a light cone with falloff and decay.
