The ExtensionString property of the Editor.ShaderGraph.TextureInput class is a string property that is used internally to store additional information about the texture input. This property is not intended to be serialized or exposed in the editor, as indicated by the JsonIgnore and Hide attributes applied to it.
Since the ExtensionString property is marked with JsonIgnore and Hide attributes, it is not intended for direct use in user code or for display in the editor. It is likely used internally by the system to manage texture input data. Developers should avoid using this property directly and instead rely on other public properties and methods provided by the TextureInput class.
// Example of how the TextureInput class might be used var textureInput = new Editor.ShaderGraph.TextureInput(); textureInput.Name = "AlbedoTexture"; textureInput.Default = new Color(1.0f, 1.0f, 1.0f); textureInput.IsAttribute = true; // Note: ExtensionString is not used directly due to its internal nature // and the presence of JsonIgnore and Hide attributes.
