The map environment are all aspects of the map that often can not be directly influenced by the player, such as terrain, weather conditions and lighting.
Beauty
Terrain, flooring, objects, and plants attribute to a tile's beauty, which in turn can affect a colonist's mood. The contents of a tile have a cumulative effect on its beauty; i.e. a granite chunk (beauty of -10) on a carpeted floor (beauty of +2) gives the tile a net beauty of -8. Certain unsightly objects, i.e. vomit, have one value when under a roof and a lower value when unroofed. This simulates the general disgust of seeing eyesores indoors versus encountering them outside.
Space
Environment space (as opposed to the Need for Space) is the count of how much space there is to freely move around in a room. This is all the floor tiles that are either empty or have objects that can be passed through at full speed, such as chairs, building materials, and the various "spots". All objects that either slow down or prevent movement through are not counted towards Environment Space. The "Space" number shown in the Environment display is this count x 1.4. This number is a measure of the entire room, and does not change depending on where a pawn is standing.
Flora
Certain plants and trees have beauty, and may also provide cover to colonists.
Light
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: 1) Relationship between light % and plant growth speed e.g. Tinctoria grows so slow in normal soil under torch light that it rots before it grows enough to harvest 2) Effects of Dark vision and Lighting:Darkness preferred on mentioned stat and mood penalties. |
Light can be generated artificially or naturally. Artificial light is produced by appliances in a limited range. Natural light is generated throughout the map on unroofed tiles. Roofed tiles will be dark unless lit artificially.
Occasionally an eclipse befalls the planet. Natural daytime light is no longer generated until it ends.
Light's importance lies in the following effects:
- Plant growth - Most plants have light requirements to grow.
- 0% only: Nutrifungus
- 0%+: Agarilux, Bryolux, Glowstool, Polux tree , Gauranlen tree , Timbershroom
- 30%+: Daylily, Rose, Tinctoria, Bonsai tree , Fibercorn
- 50%+: All other plants
- Power - Solar generators only produce power when naturally lit.
- Colonists want 30% light or better. This affects:
- Colonists' mood - Colonists in sustained darkness will have the 'In darkness' thought. Sleeping colonists will not have this thought. Therefore, lighting is not needed in areas only used for sleeping.
- Colonists' movement speed - Colonists in darkness will have a reduced move speed, scaling to 80% at a light level of 0%. Due to this, combat at night or under unlit roofed areas can lead to a disadvantage against non-human opponents, such as insects, manhunter animals, or mechanoids. Pawns that are Blind, have the Lighting: Darklight preferred precept, or have the Dark vision gene are unaffected by this factor.
- Colonists' global work speed - Similarly to their movement speed, colonists will have a work speed penalty when working in darkness, scaling to 80% at a light level of 0%. Pawns that are Blind, have the Lighting: Darklight preferred precept, or have the Dark vision gene are unaffected by this factor.
- Surgery success chance factor is optimized at 50% light or better.
There are three light levels: Dark (0-29%), Lit (30-89%), and Brightly lit (90-100%). Each tile on the map has one of these light levels. The light level of a tile is listed in the tile's information area located above the Architect menu (when the menu is minimized). The light level is immediately followed by the brightness given in a percentage (%).

Daylight timing and latitude
Daylight, or natural light, is the light generated on unroofed tiles throughout the map. The timing and strength of daylight is affected by latitude, time of year, and time of day, due to the planet's apparent axial tilt.
This effect is more pronounced at extreme northern and southern latitudes, which can result in light levels not reaching 0% at night or 100% at daytime.
Near the central latitude, light level change throughout the day as follows:
Start time | Light level |
---|---|
4h | Lit |
7h | Brightly lit |
17h | Lit |
20h | Dark |
Day Length Table
Note that the below values represent the number of hours that the light level is above 30%, meaning there is no guarantee that it will reach 100%.

Daylight math details
Warning! Trigonometry ahead! This section gets into complicated mathematical detail. Proceed at own risk |
The calculation of sunlight is surprisingly involved. On a nutshell: the formula obtains the angle between the vectors Latitude and Sun Position, subtracts an angle θ from it (determined by Latitude), and divides this number by 0.7. Finally, this result is capped between 0 (no light) and 100% (full light).
If you only care about the final formula, go to "Final formula" below. Otherwise, carry on.
The amount of sunlight a given cell receives depends on its Latitude, Day of the year, and Hour of the day. The simplified steps to reach the final value are:
- 1. Obtain the factor "u" for the given latitude
Latitude Value of u <= 70 0.2 [70, 75] Latitude * 13/50-18 =>75 1.5
- 2. Obtain Sun Position Vector SP =
{SPx, SPy, SPz}
. Do note these formulas are not in degrees, but radians.- SPx = -cos(Hour * π / 12)
- SPy = -cos(π * Day/30) * u
- SPz = -sin(Hour * π / 12) [NOT ACTUALLY USED, BUT PART OF THE VECTOR]
- 3. Calculate angle θ. Do note that the values of this table are in degrees. To convert to radians, multiply result by π / 180
Latitud Value of θ <= -60 19 [-60, 60] 36 - abs(x) * 17/60 [60, 70] 19 [70, 75] 299 - 4x >75 -1
- 4. Calculate the angle (Δ) between the vector Latitude (L) y SP.
- Δ = arc cos [ ( cos(Latitude) * SPx + sen(Latitude) * SPy ) / √ 1 + SPy2 ]
- 5. Sunlight = (Δ - θ)/0.7; Capped between 0 and 1 (100%).
Do note that the creation of the vector Latitude : {cos(latitude), sin(latitude), 0}
was omitted for simplicity.
Where:
Latitude Value of u <= 70 0.2 [70, 75] Latitude * 13/50-18 =>75 1.5
Latitud Value of θ <= -60 19 [-60, 60] 36 - abs(x) * 17/60 [60, 70] 19 [70, 75] 299-4x >75 -1
Interestingly, while some effects are applied differently above latitude 70
(70° N), these do not seem to apply below -70
(70° S). This has some odd effects on extreme Latitudes, such as the south pole having neither full darkness nor full light.
Openness
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: Large enough enclosed spaces seem to blur these boundaries. |
Openness refers to the often critical aspect of structures being open to the outside. It affects many things such as temperature, item deterioration, light, exposure to weather, and certain events.
Every tile on the map falls into one of three categories:
- Outdoors - not enclosed by any structure, even if there is a roof.
- Indoors - completely enclosed structure, completely roofed.
- Unroofed - completely enclosed structure, but with one or more unroofed tiles.
Sufficiently large unroofed rooms, approximately 300 tiles, are considered outdoors.[Detail Needed]
Temperature
Environmental temperature is affected outdoors mainly by the map's biome and by the current season. Temperature affects a plant's ability to grow. Temperature affects a human's comfort, and health in extreme temperatures.
Terrain
Terrain consists of the map's walking surface, terrain features, and mountain areas. Terrain affects things including walking speed, where plants can grow, and may prohibit construction.
Natural surface terrain includes soil, rich soil, marshy soil, marsh, mud, sand, lichen-covered dirt, gravel, rough stone (granite, marble, etc.), rough-hewn stone, shallow water, and deep water.
Terrain features include steam geysers and mountains. The steam from a geyser produces heat and an enclosed area around it will heat up unless unroofed. A mountain cannot be destroyed, even if all of its stone and ore has been mined out. What remains are terrain tiles listed as 'overhead mountain'.
Naturally generated surfaces
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: 1) Other stats. Filth masks, proper terrain affordance, driesTo, extinguishesFire, beauty, cleanliness, deterioration, special attacks, traversedThought, perceived path costs vs path costs. Note: Several can be put under a "misc" column rather than an individual one 2) Anomaly terrains - Flesh and Gray surface. |

Steam geyser
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: Specific numbers on heat needed. |
Steam geysers are terrain features that allow the placement of a geothermal generator on them and also output a significant amount of heat when sealed in a roofed room.
The steam geyser sprays after a random delay between 500 ticks (8.33 secs) and 2,000 ticks (33.33 secs). It will then spray for between 200 ticks (3.33 secs) and 500 ticks (8.33 secs). While spraying, it will output 40 heat every 20 ticks (0.33 secs). Thus, it averages 16.15 heat per second, with no maximum temperature.
Besides their use in power generation, they can also be used to heat bases and greenhouses without the need for electricity or fuel by sealing them in. Like any means of temperature regulation, geysers require an enclosed and roofed room to actually cause a change in heat. If you don't want heat, keep the geothermal room without a roof.
Weather
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: Exact details of how large fires on the map cause rain needed. Rain details should be split from the rain weather type (because its not the only weather type that includes raining) and details discussed including short circuiting, increasing fuel consumption of torch, campfire and brazier variants, which weather types include rain, whether snow counts as rain for all mechanics etc, similarly Snow and its unique effects including Snow being merged into here. |
Weather events occur from time to time depending on the biome and time of year, with the current weather listed at the right edge of the screen. When a weather event ends the weather returns to Clear. Each weather event has a general effect on wind speed.
Wind speed continually varies between 0% to 150% but it is not displayed onscreen. Wind speed is a direct multiplier of a wind turbine's nominal power output of 2300W. At 50% wind speed a wind turbine produces 1150W up to a maximum of 3450W at 150%. Note that the "max power output" listed in the infobox claims that 2300W is the maximum under "ideal conditions" - this is incorrect.
The Weather controllers can force a single type of weather to constantly appear, and will only allow natural changes in weather once it is destroyed.
Label | Time of year | Temperature range [1] | Accuracy modifier | Movement speed modifier | Wind speed | Wind speed modifier | Can put out fires | Snowing rate | Notes |

Soft snow | Mainly Winter | -270 °C – -0.5 °C (-454 °F – 31.1 °F) | 80% | 100% | None to Moderate | 150% | Yes | 80% | Weather event that can distribute Snow onto the terrain. |
Flashstorm | Any | Any | 100% | 100% | None to moderate | 100% | No | None | An extreme version of the dry thunderstorm, and an event of its own (rather than normal weather changes). Lightning strike many times in a row in a small area, igniting anything flammable and causing giant wildfires which can spread to your base easily. It also disables rain for a short time. |
- ↑ Can continue even if the temperature exits the appropriate range, once started.
Lightning
Lightning is created either naturally through thunder and flashstorms, or artificially with the flashstorm psycast. These do 10 Flame damage in a 3x3 area (1.9 block radius) and start fires in the area of effect. Dry thunderstorms can be especially dangerous, starting fires around the map without rain to put them out. The flashstorm psycast should be used with caution, preferably in areas without vegetation or during rain. Lightning can also be spawned in with a debug command in development mode.
Lightning is bright enough to momentarily power solar generators and grow plants.
Version history
- 0.0.245 - Weather (rain/fog) now affects chances of hitting a target
- 0.3.410 - Rain now slowly washes away blood. Added rich dirt patches.
- Beta 19/ 1.0 - Changed deep moving water to chest-deep moving water: walkable but slower than shallow water. Shallow water movement cost 12 -> 22. Sand fertility 6% -> 10%.
- Version/1.1.0 - Fix: Wind turbines register no wind during windy storm.
