Renderable.getSubmeshCount() always return 0

[Schlewinow]

Currently migrating an app from sceneform 1.15.0 (old Google version) to 1.20.5 of this new version. Debugging an issue with materials not being applied anymore (after recompiling the materials with the proper version of filament matc) I stumbled upon the issue that for our ModelRenderables the method getSubmeshCount() always returns 0 for every model. The models are GLB-files and rendered properly in an AR scene, but iterating over the submeshes to apply materials is not possible because the submesh count is always 0. The expected value for a rendered mesh should always be at least 1 though. This seems to be an issue since 1.16.0 and was probably never fixed (https://github.com/google-ar/sceneform-android-sdk/issues/1049).

Is there any way of getting the submesh count for renderables (from GLBs) in the current sceneform version? And how would a material be applied to a submesh of a RenderableInstance?
