I might be going crazy, but does anyone know where it went? I’m running 4r7 and I’m pretty new to ZBrush. I’m sure it’s something obvious that I’m missing.
It will only be there for a polymesh. I expect you have a zsphere selected and in preview mode. Create an adaptive skin (Tool>Adaptive Skin>Make Adaptive Skin) then switch to the new tool in the Tool palette, which will be named “Skin_”. You’ll then be able to modify the topology.
Yep, that was it. I figured it out right before you responded. Thanks so much, though!
