In order to take advantage of the potential between Blender and FVNE, you have to firstly install a plugin for blender.
If you haven't already, download and install Blender from their main website: https://www.blender.org/download/
Also download this Plugin: [DOWNLOAD PLUGIN] Credits to Fiasco for upgrading the script to be compatible to Blender 4.
Within blender, go into Edit > Preferences.
Click on the Install on the upper right of the new window, and find the .Zip file of Furryvne plugin as the installing file.
Refresh Blender, and the plugin should be installed for Cloth and Custom Offset features
Visit https://docs.blender.org/manual/en/latest/editors/preferences/addons.html for possibly more information.
We also have another that is the [FVNE Expression Manager]. (By Blacky) A simple addition for having a fully listed expression sheet (You still have to make the expressions yourself).
