Now I finally would like to do something with it, but I only received a ".ZPR" file which turns out to be 100% proprietary. Not a single free program out there can open it, no plugin for Unity or anything else. Not even the ZBrushCore Mini (quite a nifty program) can. Not even one cobbled-together thing on Github xD The original artist is not around either anymore.
Would be awesome if somebody who has a license could export it for me to .obj and .fbx =3
