I’m fairly new to zBrush. I tried to follow a video tutorial on Noise, but there was no surface sub-menu in the “Tool” panel. I use an iMac 27" (64 bit) and Snowleopard and zBrush 3.2. Can somebody enlighten me how I can acquire the missing Surface submenu?
That is a feature of zbrush 3.5, currently only available for windows. Wait just over a week for zbrush 4 and you’ll have it.
