Exporting Resource Packs - NitroxNova/humanizer GitHub Wiki
You will need the Humanizer Import plugin installed.
Once you've imported your equipment, materials, animations or targets, you will want to pack them. Open the dialogue from Project > Tools > Humanizer Import > Generate ZIP
You'll want to specify a new pack name, and select all the assets you want to include in the ZIP. you can also select an existing pack to modify and regenerate.
When you hit 'Generate' it will save the pack config and create a new zip file in the res://export folder (godot does not recognize zips so you'll have to open the file browser to see it)
You can then move the zips into any folder defined in the Project Settings > Asset Import Paths, it has "res://humanizer" and "user://humanizer" by default, but you can add more paths if needed.
