* Placeholder textures * Placeholder meshes * Placeholder material This PR is the first step towards implementing https://github.com/godotengine/godot-proposals/issues/2756 It adds an asset type that uses no resources, which can be used to replace the existing ones on export for using on the upcoming server export.
