>>30692315Ohana exports SMD format models, that's Source's format isn't it?
I've never done it before but using my sporadic knowledge of 3D Models I think you'd end up importing it to Blender or whatever, renaming the bones to match what GMod expects them to be, and exporting SMD.
Beyond finding the right programs to do it the whole process may not be so bad, a general guide on porting models to GMod / SFM would be enough. Usually people have to make whole new armatures for ripped models but not this time.
