That does seem to be what they're doing Mac, the last delay IIRC was as a result of waiting for a fix in the render engine regarding bump/displacement. So it would appear that the 3delight engine is being seperately programmed and daz are integrating that into Studio rather than writing it themselves. Makes a lot of sense to bring in a ready to roll render engine than spend the resources building one. It's worked fine for other applications so why not? Would be nice if they did something about the size of the GUI though. I know you can drag things around but those huge blue buttons and sliders are ... annoying. Something smaller and neater would have made the whole interface and interaction more pleasurable. Ahh, that's what feedback is for neh? :)
