The VRChat Avatar prefabs comes with configured Physics Bones, Visames and Facetracking (for PCVR only)

Warning:

The facetracking is already configured, and I used Gesture Manager 3 in Unity to test it since I don't own any VR Headset.

So unfortunately I can't guarantee it will work out of the box for your VR gear.

There are 4 prefabs in the unitypackage, just choose the one you want to upload to your account.

The number of bones here is the result of using armature links with VRCFury. When you upload the avatar to your account, the number goes back to the real one.

Made with Avatar Creator 3.0 in Unity Ver 2022.3.22f1

*You'll need all the packages mentioned bellow already imported to your Unity Project before adding the .unitypackage of Megumin into it.

WARNING:

Since I used Jerry's template, you will probably need to make some changes to the values of his animation parameters for the eye rotations of my model. Its fairly simple to do, just follow this guide from 2:25 onwards:

You can choose between 2 sets to buy:

The Complete Set comes with the .unitypackage file containing the Prefabs ready to upload into your VRChat account. And a bonus zip with a .blend file containing a rigged Megumin model that can be used for 3D printing.

You can pose the mesh and export it as an STL then prepare it in your 3D Slicer program of choice ***You´ll have to add all the supports yourself***

There are no ~Paper Thin~ meshes, and the cloth detail is stored in a Multiresolution modifier, so you can turn it off, pose Megumin, turn the modifier back on, apply the armature to the mesh, then export it as an STL for your 3D slicer of choice. Half the work of 3D printing is already done. But since it´s a posable model, I can´t add the printing supports for you. (Also make sure her irises are touching the sides of the eye sockets in whatever pose you put her in, they can't be floating in there)

*The Basic Set comes with the Blend file containing the rigged models, and textures.

If by any chance you don't already know how to upload the avatar, follow this guide:

You can check the finalized model in full 3D glory at my Sketchfab Page:

You're free to do whatever you want with the model. Except sell it or share it with other people, of course.
