Greetings worldbuilders! The first full update to Terra Firma 2 since release last year is now complete. This update adds a variety of disasters, each providing a unique way to interact with and modify your creations.
Meteors
Choose the size and speed then fling your space rocks ranging from (relatively) tiny blips all the way up to dinosaur killers that will completely remake the surface of your world.
Volcanoes
Volcanoes erupt over time, building mountains and then ending with the caldera collapsing. Customise the type of lava to produce mountains with gentle or steep slopes. Watch volcanic islands rise from the ocean and then erode back into atolls.
Floods
Trigger gigantic floods that wash away everything in their path.
Tsunamis
Move massive amounts of ocean water around and watch the resulting waves wash across the landscape.
Earthquakes
Warp and transform the landscape with earthquakes featuring customisable fault direction, horizontal and vertical slip amounts.
Water Physics
The water physics has been overhauled with more realistic flows for large bodies of water and ocean water now fully simulated. Sea levels can now be raised or lowered to explore a variety of different terraforming scenarios. A new configuration option makes water prefer to not run off the edge of the map.
Keep simulating when zoomed
You can now enable and disable the zoomed in detail view. When disabled, the simulation will keep running at any zoom level allowing you to closely inspect the landscape as it evolves.
Other improvements
Added a new erosion speed that can be set to any value you want
Added a visual display of current temperature
Significant rework to dirt, rock and lava makes properly conical landforms rather than the square ones seen previously
New groundwater simulation for better distribution of swamps and marshes, and plant growth in desert areas
Improved simulation of grass growth cycles
Lighting options are now saved when changed
Added hotkeys for different camera modes
Many performance improvements to the main simulation, which is both faster and uses less memory
Savefiles now remember whether the game was paused or running when loading
Water properly flows over the top of lava now
Map sides render land, ice, water and lava layers stacked properly
Configuration setting for whether sea level changes the temperature
Configuration setting for whether ocean water rises when editing land under it
Improvements to snow rendering
Added Turkish translations
Vastly improved tree and plant billboard rendering
Improved zoomed out rendering of trees and plants
Changed ice so glaciers don't flow off the map edges and cause excessive erosion
Minecraft export supports exporting to different versions (1.20.1, 1.20.2, 1.21.1, 26.1+)
Minecraft export has ores and caves
Minecraft export uses fractional water levels for smoother water rendering
Minecraft exports now have water with fractional heights
Various bugs with UI scales other than 100% have been fixed
Fixed glitches on map boundaries in Minecraft exports
Fixed the issues that Linux/Proton users were having with the UI not working
Fixed major issue with rivers depositing too much sediment
Fixed bug with lava and volcanoes not properly working on larger maps
Fixed heightmap export when image dimensions are lower than world dimensions
Fixed behaviour on map edges where dirt would form a barrier
Fixed bug with symmetrical random editing
Fixed bug with checks on road building costs in campaign mode not reflecting actual costs
Fixed rendering issue with topographic and other data overlays at map edges
Fixed 50+ miscellaneous crashes
What's next
We'll be posting a separate update to announce the future roadmap, but work is already underway on
A complete overhaul of biomes following the Koppen climate classifications. 23 major biomes and hundreds of sub biomes, more than 50 brand new trees created and animals added back into the game
A tectonics uplift system allowing land to raise over time to counteract erosion
Lots more rock and material types
A modding interface bundled with and launchable from the game, to edit or make new custom biomes, plants, animals and rock types
An export API to allow building new exporters
Steam workshop support
