Avatar Uploading

Step-by-Step Guide to Uploading Avatars & Worlds in VRChat

Uploading custom avatars and worlds to VRChat requires using Blender, Unity, and the VRChat SDK. Below is a simplified step-by-step guide to help you bring your creations into VRChat.

How to Upload an Avatar to VRChat

Step 1: Create or Download an Avatar Model

If making your own, use Blender to model and rig your avatar.
If using a pre-made avatar, ensure it is VRChat-ready (supports Unity and includes an armature/skeleton).

Step 2: Install Unity & VRChat SDK

Download and install Unity Hub and Unity 2019 or Unity 2022.3.22f1 (VRChat's compatible version) from Unity’s website.
Download the VRChat Creator Companion (VCC) from VRChat’s website.
Use VCC to install the VRChat SDK (Software Development Kit), which helps upload avatars.

Step 3: Import Your Avatar into Unity

Open Unity and create a new 3D project.
Drag your avatar file (.fbx) into the Unity project window.
Ensure the rig type is set to “Humanoid” in the Inspector panel.

Step 4: Set Up Avatar Materials & Textures

Select the avatar and go to Inspector → Materials.
Assign any missing textures or materials to your avatar.

Step 5: Configure Avatar in VRChat SDK

Open VRChat SDK → Show Control Panel and log in.
Click on Builder → Build & Publish for Windows.
Fill in avatar details (name, description, etc.).
Click Upload—your avatar will now be in VRChat!

How to Upload a World to VRChat

Step 1: Create or Download a World Model

Design your world using Blender (or download a VRChat-ready world).
Export your world as a .fbx file for use in Unity.

Step 2: Install Unity & VRChat SDK (If Not Done Already)

Install Unity 2019 or Unity 2022.3.22f1 and the VRChat Creator Companion (VCC).
Use VCC to install the VRChat World SDK.

Step 3: Import Your World into Unity

Open Unity and create a new 3D project.
Drag your world file (.fbx) into the Unity project window.

Step 4: Add Lighting & Collisions

Place lights (Directional Light or Point Lights) for proper illumination.
Add colliders (Box Collider or Mesh Collider) to prevent players from falling through objects.

Step 5: Set Up a Spawn Point

Create an empty GameObject and name it “Spawn Point.”
Move it to where you want players to spawn in your world.
Attach the VRCWorld prefab (from VRChat SDK) to your scene.

Step 6: Upload Your World to VRChat

Open VRChat SDK → Show Control Panel and log in.
Click Builder → Build & Publish for Windows.
Fill in world details (name, description, etc.).
Click Upload—your world is now available in VRChat!

Final Tips

✅ Always optimize avatars & worlds for performance (reduce poly count, use compressed textures).
✅ Use Shading & Lighting properly to enhance visuals.
✅ Test your avatar or world in Unity before uploading to catch errors.
✅ Engage with the VRChat creator community for feedback & support!
