When terraincontrol generates caves they are interlaced as if they were not a cave at all in some places. I even tried disabling canyons to make the world look better however it still generates them interlaced like this.

Could you share the settings needed to reproduce this?

Here you go, http://pastebin.com/hRqhU7W6 . I even changed canyon rarity to 0 and regenned chunks, still gens these.

That doesn't look good... Lets see if I can fix it.

Fixed. 😃

Thank you soo much. =)
