Generates a unique identifier for a resource to be contained inside a [PackedScene], based on the current date, time, and a random value. The returned string is only composed of letters ([code]a[/code] to [code]y[/code]) and numbers ([code]0[/code] to [code]8[/code]). See also [member resource_scene_unique_id].

Returns the [RID] of this resource (or an empty RID). Many resources (such as [Texture2D], [Mesh], and so on) are high-level abstractions of resources stored in a specialized server ([DisplayServer], [RenderingServer], etc.), so this function will return the original [RID].
