Changes

• Reworked large-scale terrain generation to mimic plate tectonics

  • Each continent area will now be bordered by convergent or divergent boundaries
  • These may be subduction zones, rift valleys, collisional mountain ranges, and ocean ridges
  • Stratovolcanoes are limited to subduction zones, but other varieties of volcano remain independent of tectonics

• Oceans

  • All ocean biomes made deeper, with trenches extending to y = 0
  • Atolls can now be found in tropical oceans and deep oceans
  • Removed sand-bar style islands from generation
  • Trenches are now found only in subduction zones
  • Mid-Ocean ridges occur in the deep ocean

• Island Chains

  • Volcanic island arcs form in subduction zones
  • Barrier islands/barrier reef chains form on the passive margins of continents

• Karst Biomes

  • Cenotes made larger and can have overhangs
  • Tower karsts reworked to be larger with more diverse shapes

• Volcano Changes

  • New giant stratovolcanoes in a variety of shapes, made of layers of igneous extrusive rocks and tuff
  • Stratovolcanoes replace the old cinder cones in mountain biomes
  • Cinder Cones now occur in volcanic mountain islands, on shield volcanoes, in canyons, and in rift valleys

• Carver Caves

  • Made larger and rarer

• Coastal Terrace Biomes

  • Now generates slightly overhanging cliffs more consistently, instead of occasionally generating perfectly vertically

• Rivers

  • Large rivers now carve wide river valleys through mountains and other high elevation biomes

• General

  • Plains made flatter and lower
  • Rolling hills made hillier
  • Forest soil blending improved
  • Make bamboo features less square

• Mountains (Inland variants only, oceanic mountains unchanged)

  • Generate in more solid ranges (less likely to be interrupted by plateaus etc)
  • Generate more ridges and valleys, and fewer isolated peaks
  • Made substantially taller

• Rocks and Minerals

  • Allow igneous intrusive to be present on the surface of volcanic regions
  • Allow more metamorphic rocks to be present at the surface of uplift regions
  • Allow cinnabar to generate in high-elevation rocks
  • Extend the vertical ranges of several other ores to match new mountain heights
  • Remove deep ruby ore, and move it to collisional mountains
  • Add missing gem ore info to the field guide
