This is a tool for syncing facial expression in Action layer into FX layer, which is otherwise impossible to play. The tool is built with GogoLoco in mind, yet it should work just fine with any Action layer, so long as the provided Action layer works alright. It works by simply copying entire Action layer, adding a Avatar Mask to avoid any unwanted modification done by animations, removing any extra layers, and stripping away all the State Machine Behaviors. There are some extra FX layer generation modes to choose, yet the default mode already gives the most compatiability. Install by placing extracted folder into Packages folder inside your Unity project, or by adding the `package.json` within Unity packages manage window.
