Satisfactory 1.2: Everything That Changed

1.2 is the first major update after 1.0, and it landed on PC, PS5 and Xbox Series on the same day. It is a systems update rather than a content one: very little new to build towards, quite a lot changed about how the world behaves.

Weather is back

Rain returned, rebuilt from its Update 6 version. It is presentational rather than mechanical — nothing about production changes when it rains — but it is configurable, which matters if you find it distracting.

Weather presets available in world settings:

Default
Dry
The Great MASSAGE-2 (AB)b
Clear
Raining Kittens and Puppies
Extreme

The Extreme preset was rebalanced in 1.2.1.0 after launch feedback. If you tried it in the first days and found it excessive, it is calmer now.

A fog density slider sits in Options → Video → Advanced. This is the setting to reach for if the weather effects hurt visibility in your factory more than you want. 1.2.1.0 added the same slider to Photo Mode.

Game Modes and world randomization

The bigger change, and the one that alters how a save can be set up.

Cost multipliers let you scale what things cost to build. This is a world setting, chosen when creating the save.

World randomization shuffles resource node placement. This is the significant one: the map’s node layout has been fixed since the game existed, and every guide, every interactive map and every planned build assumes those positions. A randomized world invalidates all of it deliberately.

If you want the classic experience, leave randomization off — it is not the default.

Creative Mode

A proper creative mode, with a “Give” sub-menu for spawning items. It is separate from the advanced game settings that existed before, and it is intended for building without the production constraint rather than for cheating a normal save.

Worth knowing: enabling creative or advanced settings on a save has consequences for achievements, as it always has.

Fluid Trucks

The headline logistics addition. A truck variant that carries liquids, paired with Fluid Truck Stations.

Both the station and the truck have a capacity of 3200 m³ in internal storage, and both unlock at Tier 5 as part of the usual Logistics Mk.4 milestone — the same milestone that gives you the regular Truck Station.

The case for them is elevation. Pipes lose throughput to head lift on every metre they climb; a vehicle route does not. On flat ground a pipe remains simpler and continuous.

Vehicle paths became buildable

Previously you recorded a route by driving it. Now you can place Vehicle Paths from the Transport tab using the build gun, then set the vehicle on the path.

This is a substantial quality-of-life change. Recorded routes replayed your driving, including your mistakes; a placed path is deliberate geometry. It also means vehicle paths can be included in blueprints, which makes repeating a standard road segment much less tedious.

Unreal Engine 5.6.1

The engine upgrade underpins the rest. For most players it is invisible. It is worth knowing about only because it explains why 1.2 needed a longer stabilisation period than a content patch would.

Controller and accessibility

Given the simultaneous console release, this got real attention:

Dynamic Gamepad Swap switches prompts when you change input device.
Rebindable keys on controller.
A series of controller-specific fixes across 1.2.1.0 and 1.2.2.0, including sorting Train Station inventories, “Remove all” on Player Crates, and duplicate button functionality when exiting vehicles.

Photo Mode and SPWN

Photo Mode with a Selfie Mode, plus SPWN. Neither affects production. Photo Mode gained the fog density slider in 1.2.1.0.

Daisy chaining and new buildables

Daisy chaining power connections was extended, and several new buildables were added. The practical effect is fewer separate power poles for the same coverage.

What each patch since 1.2.0.0 fixed

1.2.1.0 — Rebalanced the Extreme weather preset. Added the fog slider to Photo Mode. Fixed a crash when placing blueprints containing Hypertube Junctions. Fixed mouse sensitivity resetting on relaunch. Controller fixes.

1.2.2.0 — Crash fixes around blueprint holograms and dismantling. Fixed FICSIT Material missing from the Customizer. Fixed lifts snapped at certain angles being misaligned. Fixed a weather-related tech art issue. More controller fixes.

1.2.3.0 and 1.2.3.1 — Smaller stabilisation releases. 1.2.3.1 is the current stable build.

Does 1.2 break an existing save?

No. Existing saves load and continue. The things to be aware of:

Weather appears in worlds that never had it. Adjust the preset or the fog slider if it bothers you.
World randomization is not retroactive. An existing save keeps its node layout; randomization is a creation-time choice.
Nothing about existing production changed. Recipes, rates and power figures are unchanged by 1.2 itself, so a working factory keeps working.

If you are coming back after a long break

The two things that will actually change how you play are Game Modes and buildable vehicle paths. Weather you will notice immediately and adapt to in a minute. Fluid Trucks matter only if you have a fluid route that climbs.

Everything else in this list is refinement.

Should you start a new save for 1.2?

Only if you specifically want world randomization or a cost multiplier, because those are creation-time settings and cannot be applied to an existing world.

Everything else in 1.2 works on a save you already have. Weather appears, vehicle paths become placeable, Fluid Trucks unlock at the milestone you have probably already passed, and the engine upgrade applies regardless.

If you were part-way through a playthrough when 1.2 landed, carry on. There is no mechanical advantage to restarting, and the update did not rebalance production.

What is worth trying first

If you are dipping back in rather than reading front to back, three things give the most immediate return:

Place a vehicle path instead of recording one. If you ever gave up on truck automation because the recorded route drove badly, that reason is gone.

Check the weather preset before deciding you dislike weather. Default and Clear are very different experiences, and the fog slider is separate again.

Look at Game Modes when you next start a world, even if you intend to play normally. Knowing what the cost multipliers and randomization options do is worth the minute it takes, because you cannot change your mind later.
