Could you build this?
No Building a networked globe-sized 3D virtual world in Rust and Bevy involves low-level systems programming, custom WGSL shaders, spatial partitioning, and authoritative distributed networking.
What it would actually take: The project requires an advanced ECS architecture in Rust (Bevy), custom GPU shaders (WGSL) for planetary LOD terrain generation, and chunk streaming over WebGPU/native graphics APIs. The networking stack requires UDP-based replication (e.g., Quinn/WebTransport or custom rollback/client prediction) capable of handling spatial interest management across thousands of concurrent entities. Building this requires senior graphics engineering and distributed real-time multiplayer systems expertise.
