This is a promotional video for 4R8.....which hasn't been released yet. There is a live demo on today (13th)that this image is the advertisement for.
@Neox High Noon Pdt, Also I don't think the question was directly answered, no you can't do any renders with translucency in Zbrush as it's not supported.
to me it hints at some sort of clothsim functionality and the aforementioned render effect to be featured in the next version of Z. at least it wouldn't make much sense for them to create promotional material using apps from the competition.
tho with the keyshot bridge i wouldnt count that as competition.That said, its promotional art, don't put too much weight on it ^^
Eh......funnily enough you would use the translucent material in KS. A quick search of the KS docs would tell you that.TranslucencyThis controls how deep light penetrates into and through the surface. The higher your translucency value, the more of the subsurface color you will see coming through the surface. Higher translucency values will also create a softer looking material.
