Understanding the Requirements and Preparation

Before diving into how to upload an avatar to VRChat, understanding the prerequisites is crucial.

Unity: You’ll need Unity Hub and Unity Editor version 2019.4.31f1, which is specifically supported by VRChat. Installing different versions can lead to compatibility issues.
VRChat SDK: Download the latest VRChat SDK3 (Avatars) from the VRChat website. This SDK contains the necessary tools and components for uploading avatars.
Avatar Model: You’ll need a 3D model in a compatible format (typically .fbx). You can either create your own, purchase one, or download a free model. Ensure the model is rigged for animation.
VRChat Account: A VRChat account is essential, and you’ll need to be at least a “New User” rank. New accounts may have limited upload permissions initially.

Step-by-Step Guide: How to Upload an Avatar to VRChat

Here’s a detailed guide on how to upload an avatar to VRChat:

Install Unity: Download and install Unity Hub, then use Unity Hub to install Unity Editor version 2019.4.31f1. Be sure to install the correct version, as compatibility is key.
Create a New Unity Project: Open Unity Hub and create a new project. Select the “3D” template.
Import the VRChat SDK: Import the VRChat SDK3 (Avatars) package into your Unity project by going to Assets -> Import Package -> Custom Package. Select the SDK package you downloaded.
Import Your Avatar Model: Import your avatar model (.fbx file) into the Unity project in a similar manner.
Configure Your Avatar: Drag your avatar model from the Project window into the Hierarchy window.
Add the VRChat Avatar Descriptor: With your avatar selected in the Hierarchy, add a “VRChat/Avatar Descriptor” component by going to Add Component in the Inspector window and searching for “VRChat Avatar Descriptor”. This component is essential for VRChat to recognize your avatar.
Configure the Avatar Descriptor:
- Adjust the View Position to be located approximately at eye level on your avatar.
- Ensure the Lip Sync setting is appropriately configured. Usually, the mouth bones are automatically detected.
- Add animation overrides, if necessary, to customize your avatar’s animations.
Set up Performance Ranks (Optional): VRChat uses performance ranks to help manage lag. Adjust your avatar’s settings accordingly to help improve performance on lower-end hardware. Settings include polygon count, bone count, and material count.
Open the VRChat SDK Control Panel: Go to VRChat SDK -> Show Control Panel.
Log In: Log in to your VRChat account using your VRChat credentials in the VRChat SDK Control Panel.
Build and Publish: In the Control Panel, switch to the “Builder” tab and click “Build & Publish for Windows”. This will build your avatar and prepare it for uploading.
Upload to VRChat: The Unity editor will switch to a new scene with your avatar already setup for publishing. In the Inspector Panel, you must complete the Content Warnings section (Name and Description), as well as mark that the avatar complies with the VRChat Terms of Service. After that, click “Upload” and wait for the upload process to complete.
Select Your Avatar in VRChat: Once uploaded, you can select your new avatar in VRChat through the avatar menu.

Common Mistakes and Troubleshooting

Incorrect Unity Version: Using the wrong Unity version is a very common problem. Double-check that you are using Unity 2019.4.31f1.
Missing SDK Components: Ensure the VRChat SDK is correctly imported and that the necessary components, such as the “VRChat Avatar Descriptor,” are added to your avatar.
Avatar Not Showing Up: If your avatar doesn’t appear after uploading, check that it meets VRChat’s performance guidelines. Consider optimizing your avatar to reduce polygon count or texture size.
Errors During Upload: Read error messages carefully. They often provide clues about the cause of the issue, such as missing materials or incorrect settings.
Avatar Clipping or Glitching: Review the avatar’s rigging and weight painting in your 3D modeling software to address clipping or glitching issues.

Optimizing Your Avatar for VRChat Performance

VRChat places limits on avatar complexity in order to ensure a smooth experience for everyone. Performance ranks are determined based on a number of factors including:

Metric	Excellent	Good	Medium	Poor	Very Poor
Polygon Count	< 20k	20-40k	40-70k	70-100k	> 100k
Bone Count	< 75	75-150	150-225	225-300	> 300
Material Count	< 4	4-8	8-12	12-16	> 16
Texture Size (MB)	< 10	10-20	20-30	30-40	> 40

Frequently Asked Questions (FAQs)

Why is my avatar invisible in VRChat?

Your avatar might be invisible due to a few reasons. First, ensure the avatar descriptor’s view position is correctly set. Second, check the layering of your avatar’s components in Unity. Finally, it’s possible the avatar is exceeding the performance limits set by VRChat.

Can I use avatars from other games in VRChat?

Generally, yes, as long as you have the rights to use the model and can export it to a compatible format (.fbx). Be mindful of copyright restrictions and ensure the avatar is optimized for VRChat’s performance guidelines.

How do I fix my avatar’s textures not appearing correctly?

This issue often stems from incorrect material settings in Unity. Double-check that the materials are assigned to the correct meshes and that the texture paths are valid. Ensure that you are using supported shader types by VRChat.

What is the “VRChat Avatar Descriptor,” and why is it important?

The VRChat Avatar Descriptor is a component that provides VRChat with essential information about your avatar, such as its view position, lip sync settings, and animation controllers. It’s crucial for VRChat to properly recognize and display your avatar.

How can I reduce my avatar’s polygon count for better performance?

Use polygon reduction tools in your 3D modeling software to simplify the model’s geometry. Remove unnecessary details and optimize meshes to reduce the overall polygon count.

What are dynamic bones, and how do they affect performance?

Dynamic bones are components that add physics-based movement to parts of your avatar, like hair or clothing. While they can enhance realism, they significantly impact performance, especially with many dynamic bones. Use them sparingly and optimize their settings.

How do I upload an avatar that isn’t rigged?

Rigging is essential for animating your avatar in VRChat. You’ll need to use a 3D modeling software, such as Blender, to create a bone structure (rig) and bind the model to the bones (skinning) before uploading.

What are the legal considerations when using custom avatars?

Ensure you have the rights to use the avatar model and textures. Avoid using copyrighted material without permission. Be mindful of VRChat’s Terms of Service regarding content creation and usage.

Can I use custom shaders on my VRChat avatar?

Yes, but be cautious. Custom shaders can significantly impact performance. Use optimized shaders designed for VR and test them thoroughly to ensure they don’t cause lag or visual issues.

How do I add facial expressions and hand gestures to my avatar?

You can add animation controllers to your avatar, which define how it reacts to different inputs, such as hand gestures or voice commands. These are configured within Unity’s Animation window.

What does “poor” or “very poor” performance rank mean for my avatar?

A “poor” or “very poor” performance rank indicates that your avatar is resource-intensive and may cause lag or performance issues for other players. You should optimize your avatar to improve its performance rank.

Where can I find pre-made avatars to upload to VRChat?

Numerous online marketplaces, such as Booth.pm and Gumroad, offer a wide variety of pre-made avatars. Always check the license to ensure you’re allowed to use and upload the avatar to VRChat.
