EntityOnView

This plugin tries to optimize user experience with naturally spawned entities by restricting where an entity can spawn. Only entities that (can be seen)/seen by a player will be spawned.

Scructure entities are not included because it is not considered natural but chunk generated entities. As an example config: When a player is on surface, you can prevent hostile mobs spawning in caves, this will lead up to spawning them on surface and further optimizing experience of player. This also requires the change of maximum light level option to 15.
