Allows you to import and export glTF files during runtime and in editor. glTF is a new opensource 3d model transmission format which supports everything you'll ever need from a format in Unity. Read more about glTF here

Focusing on simplicity and ease of use, GLTFUtility aims to be an import-and-forget solution, keeping consistency with built-in functionality.

• Normals
• Tangents
• Vertex colors
• Materials (metallic/specular, opaque/mask/blend)

• ArgumentNullException: Value cannot be null in build but not in editor.
  • This is most likely due to shaders being stripped from the build. To fix this, add the GLTFUtility shaders to the Always Included Shaders list in Graphic Settings.
