Update 1.6.4566 improves gravships, shuttles, and more

Thu, 28 Aug 2025 19:32:41 +0000

Hello everyone, we’ve got a content update for RimWorld today!

Gravships have received some quality-of-life changes.

The new gravship launch interface lets you get your colony's animals and mechanoids onboard, and kicks visitors out. This makes takeoffs feel better and prevents accidental kidnappings.
The pilot console now has a "view range" tool that shows your gravship's range without going through the whole launch process.

Shuttles can now safely land on items, and they no longer obliterate a ton of roof when landing inside buildings - only the necessary roof.
When you’re in orbit, colonists won't automatically take off their life-saving, vacuum-resistant apparel if they're in a dangerous vacuum.
Mechanitors can summon the mechanoid bosses… in spaaaace!
We added a new vacskin gland prosthetic from the Empire that protects your colonists against vacuum. (This cross-expansion content only appears for those with Odyssey and Royalty).
We rebalanced the starjack xenotype to make them more useful in space - they have a new low gravity adapted gene which makes them faster and better workers while in orbit.

Other improvements include a new category for fishing in the work tab, tree sowing research allows you to grow timbershrooms in the glowforest, and the sentience catalyst now stops farm animals from roaming away.

And just in time for the colder seasons, there are new snowy visuals for trees and some plants!

We’ve also made several technical improvements to the game. We reduced the generation and loading times for worlds with 100% coverage, as well as added some tools to help our modders.

This update should be compatible with all savegames and mods. The full changelog is below to browse.

If you need to report a bug, or you’re having a problem while playing, please join us on the official RimWorld development Discord.

Have fun out there!

Changelog

Added new options to the gravship launch window to easily get colony animals and mechanoids onboard before launching, as well as to remove neutral pawns off the gravship.
Added a "view range" option to the pilot console which lets you quickly see the range of your gravship.
Added snowy visuals for trees and some plants when they’re in a sufficiently snowy area.
Added the vacskin gland prosthetic which protects against vacuum. Requires the Odyssey and Royalty expansion.
Added a “low gravity adapted” gene to the starjack xenotype, as well as rebalanced the starjacks genes. Requires Odyssey and Biotech expansion.
Bridges built in space now have unique art for their borders.

Improvements & Balance Changes

Fishing now has its own category in the work tab.
Pursuing mechanoids in the gravship scenario now arrive in two massive raids per gravship map and then stop.
The final mechhive raid will now be 50% stronger.
Improved rewards for destroying the mechhive. You now gain +50 reputation with all factions, and the colonist that destroyed the mechhive gains a larger and longer-lasting positive moodlet.
Mechanitors can now summon mechanoid bosses while in space.
Insect lair entrances are now collapsable.
Added the ability to sow timbershrooms in glowforests with tree sowing research.
Shuttles are no longer blocked from landing on items.
Passenger shuttles no longer destroy more roof than they need to when landing.
Allow quests to retarget themselves to suitable maps if they generate targeting an unsuitable one. In orbit, this allows you to accept quests that don’t work in space by flying down to the planet.
Gravships no longer clear pollution when landing.
Sentience catalyst now removes roaming and fence-blocked status from animals.
The gravship scenario now requires you to start with at least one colonist capable of intellectual work. This prevents you from becoming immediately stranded.
Worshipful village raids now occur every 24 hours and are smaller in size.
Gravships can once again land at worshipful villages.
Having a gravship on a temporary map will prevent the map from closing if all colonists are dead or gone.
Pawns won't automatically remove their vacuum-resistant apparel if they’re in a dangerous vacuum.
Planning designator shows map boundary outline in space.
Increased perceived path cost of shallow lava to discourage dangerous pathing.
More pawns from the Royalty and Ideology expansions can now spawn as starjacks.
Hermit crabs no longer walk sideways. They also live considerably longer.
Raiders won't try to ignite buildings when they are in a vacuum.
Bestowing ceremony can now be accepted in space.
Removed forced low-power mode for vac barriers when they're not in space, allowing them to still function while on the planet.
Prevented meteors from landing directly on top of grav anchors.
Added info on the grav anchor to the gravship launch confirmation.
Improved credits layout to reduce the vertical size.
Archean trees now self-heal like other special trees.
Updated links in the main menu.
Added confirmation if reforming caravan would cause your gravship to be lost.
Landing a gravship on polluted terrain now slowly fades the pollution visuals in.
Updated creative content rewards.

Performance

Reduce time required to load a 100% world save file.
Reduce time to generate a 100% world by about 40%.
Added the ability for mods to load textures from DDS files, which should load significantly faster than PNG files and potentially at higher quality.
Added custom atlas packing implementation which should allow the game to start slightly faster, while using less memory.
Improve performance when hovering a world tile out of gravship range.

Technical & Modding

Unify all MayRequire and IfModActive checks to strip suffixes, trim, and lower-case package IDs
Improved the moddability of animal abilities. It is now easier for modders to add abilities to player animals without using the Special Trainables system. Additionally, adding multiple abilities through Special Trainables is now supported.
Increased max radius of GenRadial to 80 and optimize radius calculations.
We now run back-compat code if the active mod list has changed, so that when adding expansions, all needed data is added to objects.
Fix: plant.wildBiomes wasn't checking for duplicate entries in biomes. (Only affects mods.)
Fix: Modded things with non-North default rotations not being placed correctly on gravships and prefabs

Update 1.6.4535 released

Tue, 29 Jul 2025 00:04:01 +0000

Hello, we’re back with another update for RimWorld! If you need to report a bug, or you’re having a problem while playing, please join us on the official RimWorld development Discord.

Today’s update fixes several issues people were experiencing with Odyssey. This includes multiple corner problems where buildings through corners affected room roles, beds could become prisoner beds through corners, and enemies could set fire to your stuff through corners. It also fixes diagonal walls leaking room vacuum under certain circumstances, issues with player shuttles being lost to water, as well as gravship launches causing your electrical connections to scramble.

We’re also aware of a bug where quest shuttles incorrectly try to land on water, potentially causing them to warp into your buildings. We’re working on a solution - a fix for it is currently available on the Steam unstable beta branch!

This update should be compatible with all savegames and mods.

And if you’re enjoying Odyssey, consider leaving a review on Steam! Expansions don’t get a ton of reviews, and every one helps us out a lot.

Odyssey

Odyssey enriches the world and expands your adventure beyond a single map. Build a gravship - your flying home - to travel across the planet. Settle in new biomes filled with diverse landforms and exotic wildlife. Go on quests to hunt the alpha thrumbo or raid ancient cryptosleep bunkers. Launch into orbit and scavenge tech from space stations and asteroids. But out in the void, an ancient machine mind stirs…

Tell us about your gravship adventures over on Reddit, X, and BlueSky.

Found a bug? Please report it in the RimWorld official development Discord.

Odyssey is available to play in: English, Chinese Simplified, Chinese Traditional, Russian, French, German, European Spanish, Latin Spanish, Brazilian Portuguese, Japanese, Korean, Polish, Turkish, Ukrainian, and Dutch.

We went over Odyssey’s content in our previews below, but you can also dive in blind!

Thank you very much for another awesome launch. RimWorld is nearly 12 years old, which is wild to say. What started as my alpha project and a Kickstarter now has this massive, thriving community of talented players, modders, testers, artists, translators, writers, creators, and developers. Couldn’t have done this without you guys.

I hope you have fun with Odyssey and I’m looking forward to the stories that come out of it. See you soon.
