Land generation bug

[voxelproof]

I suppose I've encountered a bug - in valleys mapgen I've found a corrupted mountain with a layer of sandstone not attached to underlaying stone core.

Are you using any mods? If so, which?

[voxelproof]

In the world this shot was taken of there're no mods activated (as I can see in "enable" menu, I understand that the 'subgame mods' are default).

I've found yet another bug in the same world - a dungeon hanging over the shoreline (see attachment 1).
There're also sometimes issues with trees spawning in the air. I don't know the source but I'm almost sure this is due to the precedency of generated features of a world - trees apparently come into existence after caves (attachment 2, mod round trunks).

The projecting dungeons are intentional, they are good for converting into player bases. But some players don't like them so in latest dev version i added a setting for an option to stop those happening.

Floating flora sometimes happens in mgv6, is that screenshot of mgv6?

I guess so. I was thinking it had something in common with overhanging giant sequoias bases in moretrees mod and floating fallen tree trunks in mg valleys (they happen quite often). Well, as far as landscape features is concerned what is a bug depends greatly on what a player regards as ugly or distracting. When I first went into some Minecraft world and saw first floating rock I was thinking it was due to a serious bug.

I am intensively exploring valleys world now. I see some vistas of compelling beauty and I also can see that it lacks two features (which as I suppose are not very difficult to implement), what makes it still imperfect. First and foremost - the sinusoidal functions behind the skylines of the mountains are definitely too obvious. Imho they should be distorted by some procedural pseudo-random noise. And second - I think that there should be "intermediate" fog - based on what is now a full distance view ('fog disabled'). It is of extremely great importance for immersiveness of MT visuals, and would make the 'suspension of disbelief' much easier :)

I've found extremely projecting one in a mg flat (coordinates and seed are visible on the screenshot). I suppose in a survival game one wouldn't be able to find this one quickly enough to avoid the hordes of hungry mobs ;)

Everything is clear now. It's not a bug of the default source. I tried out the nodebox trees mod on the world where this happened, but then switched it off. Wasn't aware that it modifies land generation, so the mystery is solved :) I will report it to the modder.

what is the subgame used on your image?

I don't know much about subgames frankly speaking. I'm not interested in subgames (I'd like to, but it's hm time-costly). I never switched on any subgames yet , but maybe there're some running by default. Really don't know.

Mapgen in the picture is flat.

'kay!

I don't know much about subgames frankly speaking.

Roughly speaking, “subgame” is just a fancy term for “game”. It's simple. Read: https://wiki.minetest.net/Subgame




Oh, and Voxelproof: If you report any mapen bugs, PLEASE do:

- Post coordinates and seed of where the bug occoured. The coordinates and seed are VERY IMPORANT for debugging mapgen bugs! The easiest way is to simply use debug mode (F5) which shows coordinates and seed in the left corner and include this in your screenshot
- Say which map generator you used (v5, v6, v7, valleys, …?) for the world in which the bug occoured in. This is also important
- Say which subgame you used (note: by default it's Minetest Game)
- Say which mods you used (note: by default none at all)
- Name the version number of Minetest

OK.

This can also occur if the filler node is "air" or a node not included in the subgame.

Check the mapgen.lua in default, or any other mods you have installed and look for this particular biome, paste what you find there in here.

I suppose if it was an unknown node there would have been pink 'unknown nodes' instead of thin air. Probably it was due to the nodebox tree mod as it modifies terrain generation and it had been enabled for a time in the world where this bug occurred before I switched it off. I never encountered anything similar neither in the world mentioned nor in any other world where no mods were enabled. It is a very rare curiosity and apparently doesn't have any significant impact on the play as it is even quite difficult to spot.
