we architects use ArchiCAD as a 3D modeling and documentation software. Nowadays we cant manage complex, high poly exterior scenes (vegetation) in Archicad, so we need to adopt other software to achieve high-quality 3d images. Without corona proxies, there is no clue for general adoption of Archicad as a rendering tool. Corona has the potential to import all the advanced rendering goodies (proxies, scattering system, procedural textures, batch renders, distributed renders,...) to Archicad. Almost all of these features are a must-have to compete with any traditional rendering environment.
Ideally, corona proxies should behave exactly as GDL objects do, id est, in particular with the ability to represent various geometry entities depending of context (we need a tree to be represented in a particular manner in a plan view, and no, just a 2D projection of the 3D geometry will not work, usually a representation of a vegetation or a furniture is dictated by some standards, not an artistic option). When looking at Archicad 3D views, this proxies should be represented in a stylized manner (probably low-poly) and it should be represented high-poly when rendering (well, this is the main reason for using proxies, a responsive work environment. Sure, also low ram memory and blah-blah...)
Hope if this clarifies and (this) architect point of view.
thanks and keep on the great work!

You have to think about Archicad's automatic reconstruction of sections and elevations. Placing objects with a large number of polygons will make these reconstructions terribly difficult. Corona Proxys will be the most important because of the difficulty Archicad has in moving objects with a large number of polygons

I'd like to open the discussion about proxies. I feel there is slight misunderstanding and misuse of proxy objects usage in AC right now.
Let's sum it up.
Proxy object ( current implementation )
The current proxy is a GDL object to help to bring custom geometry into AC from a file (like .obj or .cgeo).
Corona proxy ( NOT implemented yet )
Proxies are useful for keeping smooth viewport performance while handling large amounts of high-poly objects in the scene.
This is not implemented in the Corona for AC now - you can't select the geometry and save it as a .cgeo right now.
More info: https://coronarenderer.freshdesk.com/support/solutions/articles/5000516724-how-to-use-proxies-
Conclusion
What we want to do first, is fully implement Corona Proxy (save and load)
Making .obj importer as a separate GDL object is questionable - it's worth it and should we spend the time on this or rather on another more important functionality?
To keep the discussion rolling, will be obj. loading GDL object a useful feature? Is this a used and trusted way how to bring objects into AC? It's not better to use the objects from some well-prepared library? It's another way how to bring custom geometry into AC(plugin)?
Thanks for your feedback!

Will it be possible to import *.max files and save them as proxies?

No you would have to export the object from 3ds Max into a more common file format like .3ds or .obj or .fbx and then that is probably what you would likely be able to import.
Ideally, (if they ever resume development of the plugin) would be to convert the objects directly into Corona proxy file format in 3ds Max (the .cgeo format) and then those could possibly be imported directly into ArchiCAD using the plugin which would display the object either as simple geometry (cube or a 2d billboard or point) or as a mesh point cloud.
.max is a propriety file format that belongs to Autodesk and neither ArchiCAD nor the Corona plugin would be able to read them directly.
It might be potentially possible to create a translator (??) but I suspect that that would be too much work and you would probably run into IP legal issues with Autodesk.
(although I don't know why they are fine with everyone else's software being able to translate .DWG file format which is the industry standard in a lot of areas)
