Wow, that’s truly great news!
As for LODS, I’m only concerend for newly placed objects - an option to toggle related LOD’s would be really nice. As far as I’ve checked RAGE does batched LOD’s past certain level, those would be a nuisance for custom made maps where objects are spread differently.
But they do perform really well at long distances, perhaps a custom LOD batch tool could be implemented? Yoink remesher from blender source or something with a bootleg low res texture baker. This would allow a similar performance parity to original game world for custom maps.
This is probably in the area of wishful thinking, but I love what UNREAL has done with Octahedral Impostors, something like this would likely half poly count and add more detail to LODs. Might end up being a real performance enhancement for RAGE engine.
Modifying existing world objects would be a welcomed bonus but not essential.
