Well, just as described on the title.
I'm building an underground pyramid build, below a snowy mountain, 200x200 in size, way beyond the render and simulation distance in my server.
Once I move to one of the corners, far enough for DH to start rendering LODs, the ceiling LODs start displaying patches of snow, lava, and some blocks belonging to a structure on the surface. Apparently it's grabbing the textures of some blocks that exist directly vertical to each of the ceiling blocks.
Second picture is the view from the center of the pyramid.
Any idea if this is a setting gone wrong or anything? I've been playing around with the settings and absolutely nothing seems to be working.
