This is the ztl file of my anatomy study. It can only be opened in the latest version of zbrush 4R8.
I have also provided obj's as requested, although they are dense and don't have subdivs like the ztl.
It consists of both the posed and A pose versions.
Feel free to use this asset as a basemesh or to learn from.
Please do not use it for commercial work.
Thank you all for your ongoing support!
