Is your feature request related to a problem? Please describe.
Rendering 3D maps sometimes can be overwhelming for a single server, it would be nice if such task can be offloaded across different servers.

Describe the solution you'd like
Add features to offload rendering process to across different servers.

It can be already .. please look into BlueMaps CLI-version. By providing remote access to minecrafts world-files or rsyncing the world onto the other server, you can use the CLI-Version to render it there.
