Yo!
Hope ya'll dig cyber stuff, cuz I'm back with a CYBORG FOX TAIL!
 
This is a UNITY PLUG & PLAY product.
All you have to do is import the unity package* into your project, drop the prefab on your avatar, position and size, then attach the prefab to your hip and you're done!
 
*Unity Package requires Poiyomi 8.1+

There's plenty of colors to choose from, and because the fur, metal, and emissive are all separate mats, you can customize it in Unity to your liking!
 
INSTALLATION: 
Make sure Poiyomi 8.1+ is installed in your project
Drag unity package into your file.
Locate the Prefab in the files and drag it onto your avatar in the hierarchy.
Customize it by sizing and positioning to your liking, as well as navigate to the Materials folder and explore what colors you'd like to use.
Drag the prefab onto the hips in your avatar's armature.
You're done :)
