Hi Sigh4,
When I attempted to import a model form Zbrush 3.1 into Zbrush 4, it crashed when previewing an adaptive skin on my model. It sounds like you have a similar issue to solve. I do hope there is an answer really soon mate.:idea:
I’ve got a core duo 2.66 mac book pro with 8 gigs of ram (early 2009)
It seems to run Zbrush 4 fine but the fan also kicks in really early and gets really hot.
