Indirect light is the best way to produce realistic images, but for now is too much slow and it don't work very well in my opinion, too much artifacts. No blurry transparencies and the blurry reflection are incredibly slow too. Every reflective surface in nature have a little blur. Also, it's difficult to create realistic glass in carrara compared to other softwares. The last, the caustics, that are not precise enough for my taste. We'll see, unfortunately some of my clients aren't blind and i really need to be competitive on the market. This is the hard world of job:-( -TOXE
