How to load custom extensions?

[Sigma-ph]

My custom extension was loaded as SharpGLTF.IO.UnknownNode type, but this type is private and inaccessible. Is there any way to register a custom extension loader?

That's to be expected since the glTF reader does not know anything about your custom extension.

Before using your custom extension you need to register it into the library using SharpGLTF.Schema2.ExtensionsFactory.RegisterExtension method.

I have no idea how did you define your extension, but it requires you to write some classes that match your extension architecture and then you register these classes with the aforementioned method.

You can find how yo create and define extensions for the library in the AGI extensions library:
