For some reason, this takes over a second to render 2 chunks, around 0.55 seconds to render a single chunk (the quickest it's ever rendered a chunk was 0.503 seconds) and from almost a minute to over a minute to render 100 chunks. Don't try adding decimals here as that will break the system, if you want decimal values you'll have to manually add it to the list 'AcceptedNumberValues'.
If anyone can make this quicker, please do! I made a random map generator because I was too lazy to manually type in 100 values You can check how much each individual chunk took to render in the in-files list 'TimeTaken all'
