An edit to the AvaTaur: removed upper body so you can put your own top half on it.

This unityproject only contains the PREFAB. For the prefab to function you MUST OWN VOXIAN'S AVATAUR

To make the process less painful, I've created a janky script that will help you match the bones of the avatar you're putting onto the AvaTAUR's

A .PDF guide and the script has been added to the downloadable files.

Your avatar needs to have rotation constraints set to follow the AvaTAUR's --- HOLDER --- bones.
The script will generate a list like this for you so you can use it as reference.
