I made a free tool for packaging SFM models into release ZIPs
SFM Package Builder is a free Windows tool for people who port, edit, or release models for Source Filmmaker.
Select your compiled model and materials. The builder gathers the related files into the correct SFM folder structure and lets you rename the release copy without changing your originals.
It can also generate an installation README, check for packaging problems, and add rigs, configs, and documentation.
Save the package as a project, then reuse it whenever you need to build a new ZIP from your latest files. This makes it easier to update a model and publish new releases.

Do not navigate outside the asset page. It is SFW but the rest of the site is an SFM furry fetish site. Roam at your own risk.
Feedback is welcome from anyone who releases or ports SFM models.
