Where is the mega list of past ZBrush tutorials?
ZBC tutorial list is small, where’d they all go?
What ‘mega list’ are you referring to? There are plenty of tutorials in the Tutorials forum dating back a long way. There are also some in the online docs. For 3.5 a good place to start is Artists Tips and Tricks . If you want older stuff then look at the bottom of the Older ZBrush versions Table of Contents .
You should remember that tutorials for older versions of ZBrush won’t necessarily be easy to interpret for the current version.
