Biome backgrounds are images that appear behind objects and blocks in each biome. A few of the Calamity Mod's biomes have unique backgrounds that usually show a landscape of the biome. Backgrounds do not affect a biome in any way. Turning off backgrounds in Settings hides them, though ambient objects will still appear.
Surface backgrounds[]
The Sulphurous Sea's background.
The Astral Infection's main background.
The Astral Desert's background.
The Astral Snow Biome's background.
Underground backgrounds[]
These backgrounds consist of only one layer, unlike surface backgrounds.
