Hi Wiktor and thanks for your response. On the topic of having multiple levels of detail i would assume that multiple models with different poly counts will be uploaded for the same object, as that is the standard approach used in video games. For doing that i would have two entities: object and model where the object would have multiple models within it.
I would have a unique id for every object and will provide endpoints for accessing the models. References to objects can be established in OSM by keeping references to object ids. As for scale conversions i think that the main issue would be to find out the correct scale based on user's input, so perhaps it would be the best to provide a unit standard (for example 1 blender unit = 1 meter) and in this way we can defer the required scale to 3d modellers instead of trying to guess or approximate scale.
