Q&A: Best workflow to work with Humanoid models?

As Unity Animation window doesn't support direct editing on Humanoid rig models, we need to make/edit on the Legacy/Generic duplicate and generate Humanoid clips with DAE exporter;

Assume we have a humanoid model called "Dog_H";
if you're going to make many animations for it, then duplicate one as Generic (e.g.: Dog_G) and always keep it in your project.

From now on, you make and edit clips on the Dog_G model, then export the clip into corresponding DAE archives to get the Humanoid clips for Dog_H or other humanoid models;

Whenever you need to update a clip, just do it on Dog_G; when you're finished, export it to overwrite the corresponding DAE for that clip;
