Project Requirements

To use our SDK correctly you will need to do a few steps to make your Unity project compatible:

Include shaders in the build

The new avatars created using the shaders from GLTFast. While this will work always in the editor we need to tell Unity to always include this shader in the build because otherwise they might be missing.

The most recommended way to do it is by using the Shader Variants Collection

Unity Documentation: Shader variant collections

https://docs.unity3d.com/Manual/shader-variant-collections.html

Unity Documentation: Shader variants

https://docs.unity3d.com/Manual/shader-variants.html

Choosing the correct variants of a shader in a Shader Variants Collection might be a difficult task. The easiest way to select them is by generating the currently tracked list of shader variants that the Editor uses:
Edit → Project Settings → Graphics → Shader Settings → Save to asset...

Don't forget to add the Shader Variants Collection in the Preloaded Shaders List under Shader Settings.

Unity Documentation: Get a list of shader variants the Editor uses

https://docs.unity3d.com/Manual/shader-how-many-variants.html

Or, you can directly add the shaders in:
Edit → Project Settings → Graphics → Always Included Shaders

You will find the shaders in:
Packages/com.atteneder.gltfast/Runtime/Shader

info

You will need to select the adequate shaders depending on your Render Pipeline. By default Union Avatars are imported using a PBR Metallic Roughness shader

caution

If you are still having issues with shaders, please read the documentation of GLTFast to make sure your project meets their requirements.

Check the requirements in the Editor tool

In version 2.0.2 of our SDK, we added a new window on the editor tool to check for the requirements of the project.

tip

You can find this window anytime at the top-bar:
Union Avatars → Project Setup
