Great script.
I am trying to render a full map view of a world and the chunkList array is rather large.
Do you have nay idea how to insert the chunkList array into a scene via commandline in order to run the entire process headless ?
The world (10k block radius) is too big to open in the Chunky gui to manually select chunks for a scene.
