Hello! First of all I would like to say that your mod helped me a lot, thank vou.

I would like to know if there is a way to change the radius to fix 4 blocks above the player. Currently it fix only 3 blocks above the player. And btw I use the 1.10.2 Minecraft version.

Sorry, no, the number of packets sent to the server is already high enough. And honestly, 1.10.2 is just too old for me to still support.
