Duplicate a part of a model

[Qheb]

Hello,

I am using Filament in an Android application for displaying a model loadel from a glb file using gltfio.

I am looking for a way to copy a part of the model (an entity, with it's vertices, material and animations) so I can display it in several places in my scene.

I first tried to recreate a renderable using the RenderableManager.Builder, but I found no way to retrieve/copy the vertices of another entity. And it looks like I would have had the same kind of issue with the animations.

I then found this discussion about instancing, and I succeeded in creating other instances of the whole model. But I find it quite tedious to search for the exact entity that I want to duplicate in the whole list of original & duplicated entities. (And I guess it is not very efficient to duplicate the whole model in order to keep a single entity).

I am thinking about moving the parts that I want to duplicate in separated glb files, so I can instantiate it individually as I want, but this requires a bit a work since the current ModelViewer only supports loading one glb file.

So before starting on this way: Is there a simpler or more practical way to duplicate a part of a model loaded from a single glb file ?

Thanks!
