Basics of Creating a VRChat Avatar | From Scratch

Education

Introduction

Creating a VRChat Avatar from scratch can be an exciting and rewarding experience, especially for PC users. In this detailed guide, we will walk through the process using Blender to model the avatar, rigging it for animation, and importing it into Unity for use in VRChat.

To begin, open Blender and import reference images for your avatar. Use the UV Sphere to create the basic shape of the avatar and then sculpt and mirror modifiers to form the different body parts. Use the Boolean modifier to connect overlapping parts and the mirror modifier for symmetrical body parts. Once the modeling is done, export the avatar to Unity.

In Unity, install the VRChat SDK and import the avatar model. Configure the rig as humanoid and check bone placements. Add the VRC Avatar descriptor component, adjust the view position, and upload the avatar to VRChat using the VRChat SDK.

Throughout the process, ensure weights are properly assigned to bones for animation, add materials to different parts of the avatar, and apply any special effects like outlines using modifiers. Finally, upload the completed avatar to VRChat and test it out in the virtual world.
