A plugin to optimize MapEditorReborn schematics.
Basically, the primitives becomes fully client sided ( you can configure them in the config to exclude certain parts of your schematics ), so the server isn't affected by the performance of primitives anymore (it even boosts a little the FPS of the players, don't ask me why idk).
A feature also exists to load/unload primitives for each players depending on their distances with the primitives, if a player is too far away from a primitive, it will despawn for him.
It can also be used as an API to handle client side primitives, spawn/unspawn them easily (using the ClientSidePrimitive class )
Everything is explained in details inside the readme of the plugin, a lot of things is configurable via the config. ( if you just want the part where primitives are client sided to gain performances on your server and nothing more, you can disable the cluster part )
