I'm sure you're long done with 1.12, but I'm trying to find a way to increase the render distance of waystones. They currently use the same render distance as a vanilla chest, which is quite short when out exploring the world.

Any chance there will be a config option to change this? Or if there are any other solutions, I'm open. Thanks!

Minecraft 1.12 is no longer supported so unless there's some other mod that allows changing render distances there's nothing you can do.
