How to Make Your PC Avatar Quest Compatible

In this tutorial, we will guide You on how to make your PC Avatar Quest compatible. We will walk you through the process of duplicating your PC Avatar project, installing the Android SDK, fixing errors, optimizing the avatar, and finally uploading it to VR Chat for both PC and Quest platforms.

Introduction

If you've been following our previous episode on how to upload a PC Avatar, you can now take the next step and make it compatible with the Quest platform. By duplicating your existing PC Avatar project and performing a series of steps, you'll be able to convert it to the Android SDK and upload it to the Quest side of things.

1. Duplicating the PC Avatar Project

Before we begin, we need to duplicate our existing PC Avatar project. By creating a duplicate project, we ensure that our original project remains intact while we make changes specific to the Quest platform. To do this, locate your project file inside Unity Hub and simply copy and paste it. Keep in mind that duplicating the project may take some time.

2. Installing the Android SDK

To proceed with the Quest compatibility process, you need to ensure that the Android SDK is installed on your system. Go to Unity Hub and navigate to the "Installs" section. Check if the Android module is installed by selecting the version you're using and verifying that it includes the Android option. If not, click on "Add Modules" and install the Android module.

3. Locating and Opening the Project File

Once the project has been successfully duplicated, rename it to something identifiable, such as "Quest." Close any open windows, go to the top of Unity Hub, click on "Add project from disk," and search for the duplicated project file. Select the file and add it to your Unity projects list. You will now have the duplicated project ready for modification.

4. Switching Build Target to Android

Before making any changes to the project, we need to switch the build target to Android. In Unity, go to the VR Chat SDK, Show the control panel, and log in. In the control panel, navigate to the "Builder" tab. You will find a button labeled "Switch Build Target to Android." Click on it to initiate the build target switch. Note that this process may take around 30 minutes, so be patient during the switch.

5. Fixing Errors in the Console

After the build target has been successfully switched to Android, you may Notice several errors in the console. These errors need to be addressed before proceeding with the upload. We will go through each error and make the necessary changes.

  • Changing the Shader: The first error commonly encountered is the unsupported shader used in the PC Avatar project. We need to change it to a VR Chat mobile shader. To do this, find the "Shader" option under the body drop-down menu and select the appropriate VR Chat mobile shader for each material. Repeat this process for every material in your avatar.

  • Removing Fizz Bone Components: Another error you may encounter is having too many Fizz Bone components. These components can cause issues with the Quest platform. You can choose to remove one or more of these components, such as hair, tail, or breasts, depending on your avatar. Simply click on the component in the avatar hierarchy and remove it using the "Remove Component" option.

  • Fixing Missing Textures: If the console indicates any missing textures, you need to locate and add those textures to the appropriate materials. Make sure all textures are included to avoid any rendering issues on the Quest platform.

6. Optimizing the Avatar

At this point, you have resolved all the errors in the console. However, to ensure optimal performance on the Quest platform, it is recommended to further optimize your avatar. There are various ways to achieve this, such as reducing polygon counts, simplifying shaders, and optimizing animations. While these methods go beyond the scope of this tutorial, you can explore them in additional resources to enhance your avatar's performance.

7. Building and Publishing the Avatar

With all the errors fixed and the avatar optimized for the Quest platform, it's time to build and publish the avatar. In Unity, click on "Build and Publish," and the build process will begin. Once completed, you will have a ready-to-upload avatar for both PC and Quest platforms.

8. Uploading to VR Chat

With the build complete, it's time to upload your avatar to VR Chat. Ensure that your VR Chat account is logged in, and click on the "Upload" button in Unity. Follow the upload process, and wait for the avatar to be successfully uploaded to VR Chat. Once uploaded, your avatar will be compatible with both PC and Quest platforms.

Conclusion

Congratulations! You have successfully made your PC Avatar compatible with the Quest platform. By duplicating the project, switching the build target to Android, fixing errors, optimizing the avatar, and uploading it to VR Chat, you can now enjoy using your avatar on both PC and Quest platforms. Remember to ensure consistency in VR Chat parameters and avatar ID to avoid any compatibility issues.
