Free model regen?

First thing. ScriptingHelpers is not a request site. You should post a script and ask for help troubleshooting it.

Second thing. To regenerate a model in ROBLOX Studio, you have to create a Backup of it, then Delete the original model (optional), and last re-create the model from the Backup.

I won't give you a script because of my above statement, but this should be enough for you to think on how to write it in a script. When you finish the script, then you may post it here to ask for help.
