[UNSOLVED] Attaching Data to Chunks

[atrain99]

I'm working on adding a pollution api into my mod, and I was wondering how to attach the data to chunks when a world is saved, much like thaumcraft does the vis and taint.

Does nobody know how to do this? Must be one of azanor's closely guarded secrets.

There is a save handler somewhere I think, not used it personally though.

Speaking of which, what's the best way to attach data to a specific player (to be saved and loaded with the game. This also needs to work for multiplayer.)

Bumping because I'd like to know how to do this as well, I need to add data to chunks and let the client know about it. Is there a hook for when a whole chunk is sent to the client?
