NPCs and Open world

[Haoris]

You need to split your World in multiple chunks. Each Chunk is a new Level, with NPCs, Enemies… etc

Now you need Level Streaming to generate a full world out of your chunks. Only Load visible Levels inside Player Radius. Unloaded Levels and theor NPCs won‘t consume resources.

Plus I’m using world composition

They are already unloaded while distant tiles are unloaded and replaced by low LOD landscape mesh.
And that’s not what I’m looking for. In almost every Open world RPG, NPCs fade in/out at a certain distance around the player.
When they walk out of this distance, they fade out. When you follow them and you’re close enough, they fade in and keep walking from the location they faded out.
