AutoMZP Maker is a 3ds Max script made for creatives who want to focus on their scripts without wasting time building self-installing packages. It helps maintaining consistency across different scripts and versions, and makes the tedious export process faster.
It offers both a tool for making a complete .mzp package and one for encrypting .ms files only.
