Just to verify that ZB5 will in fact be a 64-Bit app. Read here : https://support.pixologic.com/index.php?/Knowledgebase/Article/View/66/0/is-zbrush-4r2-64-bit
Actually I think it is a bit. Max wins in 66% so people just as I did might get a wrong impression. Of course I get that at 4k PolyUnwrapper is much faster than max.
Nothing really changed with the jacket texture between the two, I think it was just lighting. I'll match #66, but I'm probably just going to call it here (for now).
