The FX template is named “_BW_FX”.
It contains the essential layers commonly used by avatars; you can duplicate and expand as you see fit.
Note
v1 and v2 have almost the same FX Controller; the only difference is a slightly different approach with the Presets Layer.
Caution
The animator is written in a full Write Defaults ON workflow.
