Using zb v3.2 mac, I can’t render larger pictures than 1024 px or heavy meshes as 5M faces. ZB works perfectly with much heavier meshes, I can export any resolution as preview render (this is what I do), but not quality. ZB just crashes and the crash report says (as expected) memory problem. When zbrush tries to use a page file (you here the HD) it just crashes.
BTW lazy tool doesn’t work either (ZB crashes)
No other problem though
