sonaar Will check how to approach this as RN presets are carrying this data - for eg. if some third party content creator will want to make a preset for RN they may deliver for eg. materials only for Octane and Maxwell at the same your default remembered V-Ray won't be applicable, the same with geometry some may deliver only full objects without proxy option, or only proxy without full, or even something else than full and proxy if they will need to do so.
In the case of Renderer and RN library by default, it is set to Auto, if your current renderer is set as V-Ray (I mean in Rhino) it will auto pick it, so you have only to pick proper geometry mode.
