Hello, I need a specific crate spawner on my map to be recognized by Monument Addons so that it can in turn be automatically scaled by Entity Scale Manager when it spawns. This is a special crate with a custom loot profile placed by Rust Edit, so I don't think that I can simply create the crate again with Monument Addons?

There's no way to register existing entities with MA today, though it's been suggested a few times.

Even if MA were to spawn this entity or know about this entity, loot crates need to function differently as they need to be respawned periodically, which uses the Spawn Group/Point feature of the plugin which doesn't support scaling today.
