Updated: Added Unity 2018 compatible package in addition to the original 2017 package
This is the VRChat avatar package for Unity, prepared for upload! The model and files are available free on Sketchfab if you want to configure it for upload yourself at no cost:
Make sure you import the VRCSDK2 and Dynamic Bones into your project before the avatar! This one also requires that you have Blender installed for Unity to play nice with the model file. Double-click the scene file in Assets after everything else is installed and imported, to load the avatar. Then you can begin customizing or uploading.
If importing gives you trouble, try reinstalling Blender, then in Unity Assets, right click and reimport "Akita.blend"
