Aurora Borealis - OreCruncher/BetterRain GitHub Wiki
Auroras are special nighttime features that are spawned by Dynamic Surroundings if a player is standing in a biome that is considered a polar type region. Examples of such biomes are Taiga and Ice Plains. Auroras a strictly visual and do not affect game play or mechanics.
An aurora will spawn based on the following conditions:
- The player’s dimension has a sky.
- There isn’t another aurora within 400 blocks of the player.
- The player is standing in a polar biome.
- It is nighttime.
- The brightness of the Aurora is influenced by the moon’s brightness.
In general the Aurora spawns north of the current player location. However, on multiplayer servers it is possible that the Aurora can be in a different cardinal direction if it already has spawned because of another player. Auroras are reset/cleared when daytime occurs, and will be newly generated when it again turns night. Note that a player can see an Aurora even thought they may not be in a polar biome.
Aurora behavior on a client can be customized by the player. A player can choose to disable Auroras independent of the server settings. Also, a server owner can disable Auroras meaning that no players attached to the server will have them.
aurora { # Animate Aurora [default: true] B:Animate=true # Whether to enable Aurora processing on server/client [default: true] B:Enabled=true # true to keep the aurora at a height above player; false to fix it to an altitude [default: true] B:"Height Player Relative"=true # Allow Auroras with multiple bands [default: true] B:"Multiple Bands"=true }
A polar biome is a biome that has one of the following words in it’s name: “taiga”, “frozen”, “ice”, “tundra”, “polar”, “snow”, or “glacier”.
To find out more information about what Dynamic Surroundings thinks of a biome look at the log file that is generated by Minecraft/Forge. The following is an example of what can be found. In my case I had the Enhanced Biome mod installed when I was testing.

Credit has to be given to MrRube and his Aurora Rubealis mod for 1.4.7 Minecraft. This mod shaped the functionality within Dynamic Surroundings and gave good examples of how Auroras can work.
Check this page out for why auroras have the colors they do.
- An Aurora may not display correctly if you are using an external shader pack. You will have to a) use the internal shaders, or b) disable auroras in your config. The problem is display and does not affect game stability.
