This page needs a lot of cleanup and reorganization. I plan to do this as soon as my headache subsides. - N3X15 (talk) 14:37, 11 August 2020 (CDT)
Note: YMMV: This guide was originally written back when Avatar 3.0 was initially released.

Tools

Prerequisites

  • Unity 2018.4.20f1 (Download from here using the Unity Hub.)
  • A lot of Hard Drive space (Recommended dedicated HDD)

Optional

The optional tools are exactly what it says on the tin, however they can help by massively simplifying the process of porting an avatar to 3.0 or adding features you like.

Setting up Unity

TODO: Unity shit here

Downloading VRC SDK

  1. Log into https://vrchat.com/home/login
  2. Navigate to the Download link on the left sidebar, and download the VRCSDK3-Avatar .unitypackage. You MUST use the avatar version.
  3. Save the .unitypackage anywhere.

Setting up the project

  1. Open Unity 2018.4.20f1.
  2. Create a new 3D project on a HDD with plenty of space.
  3. Drag the VRCSDK3-Avatar unitypackage into your assets tree.
  4. Extract everything.
    • You probably want to do the same with Dynamic Bones and other packages.
  5. Disable baked lighting:
    1. Open Window > Rendering > Lighting Settings
    2. Uncheck Mixed Lighting > Global Illumination
    3. Close the dialog

Creating an Avatar

  1. Drag your FBX from the Assets Tree into the Scene.
  2. Set up your materials.
  3. Right-click the avatar's root node in your scene and select "Unpack Prefab".
  4. Select your avatar's root node in the scene.
  5. In the right component sidebar, select "Add Component".
  6. Search for and add a VRC Avatar Descriptor component.
  7. Set your viewball to be directly between your eyes. (View > View Position, look for the little white ball)
    • Do not move it forwards to avoid clipping; The game's IK has changed and this old trick will actually cause more problems than it used to solve.
