Models and motions.
poser5 ships no third-party character models or motions. Everything you pose is loaded from your own machine and stays there. If you distribute renders or scenes made with imported assets, the original creator's license still applies — check it before you publish.
Thanks
To the three.js, pmndrs and pixiv maintainers whose work makes a browser-based rigging and posing tool possible at all, and to the testers who filed the bugs behind most of the changelog.
