Terrain and LOD

Regarding the terrain editing tools, I would like to gather everyone's opinions. I plan to implement features related to terrain editing and LOD (Level of Detail) by modifying Blender's source code, and I'm curious about what expectations everyone has for such a feature.

My original idea was to create a separate "MeshGroup" object, similar to a Group in 3ds Max, which could contain many instances. Then, by adding an "LodTree" modifier to the "MeshGroup" object, it would be possible to switch based on the camera distance.

However, someone else suggested writing a script for an empty object that switches the visibility of child objects based on the camera distance, which could also achieve the visual "LOD switching" effect.

Nevertheless, I believe the most challenging task is how to create sculpting and projection tools for multi-level detailed terrains with LOD, and how to batch bake when multiple LOD textures are different.
