3 years ago Here's a view of the first Corner "Far Lands". Not too much special looking about it:
If we go onto the tubes on the right, we reach a clearing. And looking to the left reveals what looks to be literal Edge Far Lands (and probably is Edge Far Lands - since one noise generator hasn't overflowed in the clearing and finally overflows past that point) staring right back at us despite already being in the other set of Edge Far Lands:
Yet if we were to fly into one of these tunnels, what we would be greeted with is another set of Edge Far Lands, which again are pointing perpendicularly to this set:
And a view of those from a clearing:
Actual Corner Far Lands looking terrain is pretty rare in this region.
And the corner far lands, at least when far enough that both noises have long since overflowed, look pretty standard:
A couple other things I decided to do after this, alongside lowering height offset and the sea level to 0 and -1 and making the vertical edge far lands spawn at the other edge far lands distances, was to mess around with this some more. Since selector noise is what is used to determine whether high noise or low noise is used at a given point, having it overflow before low or high noise did would yield interesting results. So I set it to overflow at half the far lands distance, and it of course yielded some rather interesting effects.

For the fartherer lands, the jump in the terrain only appears in Forge and not vanilla (as I have documented in this repo), but the terrain does jump back eventually:
Here's a few more very interesting details relating to the Far Lands that could warrant investigation or a mention.
Sheet Far Lands
Interestingly, this one can be generated completely in vanilla (14w17a-18w05a) using Customized world settings. If we set the coordinate scale to 532676640, we get a world that looks pretty rough as one would expect. However, teleporting to exactly 2,097,152 blocks out brings us this freak of nature:
These thin walls can absolutely intersect themselves as one would expect (they generate on both axes), which can result in 3x3 versions of The Stack.
And yes, they can mix with the Sky Far Lands in about the way you would expect:
If we increase this be 32 (the minimum number it can be increased by as coordinateScale is a float) to 532676672 the first sheet now appears at 1,048,576 (2,097,152/2) blocks, and adding 32 again to make it 532676704 causes it to be at 699050 blocks (2,097,152/3).
If instead of doing this for coordinateScale, we instead set this number for one or both of the depth noise scales and teleport the expected distance, a ridge can be found in that exact same location:
Low/high noise disjoint generation
The usual Far Lands are caused by the simultaneous overflowing of what are know as low noise and high noise. While usually inseperable in vanilla (although proving this otherwise would be great), CubicWorldGen allows them to be configured separately, and this of course allows them to overflow at different distances, causing exciting effects. In the following examples, low noise is set to overflow at twice the usual Far Lands distance on the X axis, and high noise twice as far on the Z axis, in order to see how weirdly these can mix.
Positive X (high noise only)
Positive Z (low noise only)
And when we go to 25,101,640 blocks out where both should be overflowing, terrain just becomes outright unexplainable. There are tunnels underneath other tunnels that run completely perpendicular to each other, and so on. The proper boundary can be seen in some cases, but only some.
