Hey!
This is my first post so sorry if I make mistakes but I just got Zbrush 3.2 working and had to share.
Once you have downloaded drag the 3.12b file into the 3.12 folder.
The 3.12b file contains instructions how to patch the software. It's stupidly easy so don't stress.
Zbrush 3.12
Zbrush 3.12b
Zbrush 3.2
Enjoy!
Oh if anyone wants me to make more of an effort with instruction just say.
