shed, poser already has GI (which calculates indirect lighting with results somewhat analogous to renderers using radiosity) but I can't say that its algorithm is similar to (or as elegant as) those created by autodesk, which was apparently unable to purchase poser from smith micro last year.  it's true that poser's version of GI (FFRender) is prone to various artifacts and is a bit slow, but they are aware of the problems and they know that users still posting poser 4-style renders in 2009 is one of the reasons that poser is the laffing stock of the 3d-snob community.
