I’m late to the discussion but the “all this reveals is b!d does not really know how to use 3Delight” argument does not apply to Daz Studio. While 3Delight is a very powerful rendering engine Daz Studio by default curtails much of the functionality to keep it simple for less experienced users, and does not really open up much of the higher functions for the more experienced ones with the exception of the uberenvironment that comes bundled with the pro version of Studio and some 3rd party shaders, even then your still limited to scratching the surface. As a result users of Daz Studio often need to venture outside of 3Delight in order to create realism and Cycles is a viable option. The cycles mantra might be a qualified bone of contention but 6 years of Daz Studio development and little has changed to opening up the higher functions of 3Delight. If anything Daz Studio has approached an even more simplified rendering interface complete with rabbits and turtles that obscures the real functionality like bucket sizes, raytracing bounces, etc.
anyway thanks for the link, it was what I was looking for.
