I meant a library folder, not the library pane, when I wrote external library. I’m not sure what the current official term is - we always used to say Runtimes but that seems not to be used as often. Any way, the path i gave is the path for the actual “definition” files, placed by the core installers, and that is where the geometry, uv maps and morphs live so Poser needs access to it - either in the same library folder as the companion files or in another that is selected in Poser as an external library/Runtime folder.
I’m not sure I understand, but my program is here:
Applications/Poser Pro 2012/Runtime/
the Runtime I have everything saved to including where the companion files are installed here:
