[Interest] [Qt3D] Render same geometry to multiple Scene3D nodes

I have a big amount of data to render (a point cloud) which changes every frame. Also I have multiple Scene3D nodes where I want to visualize the geometry with different camera views. I have one root entity which holds 3d objects and since an entity can have only one parent, only one scene shows the picture. Duplicating the geometry for every view will a lot of processing time and I'd like to avoid that. How can I achieve what I want?

Best regards,
