Over the past two years, this project was used as a testbed for project techniques due the the large amount of optional attachments. Over that time, I learned many new things and Blender has also changed quite a bit (especially with the pose library). Most of the changes from the M1 version was to fix the armature and apply a stable way of handling controllers within animations. If you want to take a closer look at this project setup, it is available on Gumroad
