Just shows 0 tiles.

@untuned Did you just create the nether/end? The tiles might not have been saved to disk yet. Try /save-all before /bluemap render please :)

No, these worlds have existed since the start of the server. Even if I stand in the nether, it doesn't do anything. Console shows no errors either.

@untuned hmm.. in bluemaps configuration for the nether map, is world: pointing to the correct dimension folder?
(If you are unsure, maybe you could show me your config and the folder-structure of your worlds)

It's definitely correct, the world is named "world_nether".

# Here another example for the Nether-Map
	{
		id: "nether"
		name: "Nether"
		world: "world_nether"
		
		skyColor: "#290000"
		
		renderCaves: true
		ambientLight: 0.6
		
		# We slice the whole world at y:90 so every block above 90 will be air.
		# This way we don't render the nethers ceiling.
		maxY: 90
		renderEdges: true
	}

@untuned ooh .. okay thats interesting .. i am not that familliar with bukkit .. i just tried it myself with a server and noticed that bukkit is doing sth really weird with it's dimensions:
You actually have to configure world_nether/DIM-1 and world_the_end/DIM1 for it to work .. so the default values i put in the config are wrong ^^'
Try that and it should work, tell me if it did! Thanks for the report! :)

Trying that makes it so I can't render it apparently.

Oof, okay i think know why. That's a bug in the code then.. I'll fix that.
