https://www.babylonjs-playground.com/#EC6R4F#20 So it "works" but it crashes once it propagates out a little. I need an idea of how to establish which zones to build.   Maybe like a max ring size instead of what I am doing now and have it only render out say 4 steps from the current zone the player is on? Just hoping for some alternative ideas. http://www.babylonjs-playground.com/#EC6R4F#19 ^^ for a non crashing version without neighborhood checks. #EDIT# Also any math buffs
