Fractum - biome mod
by Gloxinia_04
Fractum, a Forge and NeoForge biome mod, adds new overworld biomes, structures and mob variants to the world generator.
What it does
The mod adds overworld biomes that include the Marshland and Savage swamp, the Sky ruins and Fire plains. Each biome uses its own block palette, so the colors and surface materials differ from vanilla areas. Biomes are generated through TerraBlender, which is required and has to be installed alongside Fractum.
Fractum adds new structures, including a sky temple, and new mob spawns: will-o-wisps that appear at night and can be caught with a lantern, fireflies at night, and mosquitoes during the day. Vanilla mobs also receive new variants. The mod also adds ambient features such as floating islands, crystals and giant plants.
Files are published for Forge and NeoForge only, under the Apache License 2.0. The code is not open source. The client-side only environment means the mod is installed on the player's side and does not need to run on a server.
Key features
Swampy overworld biomes
Marshland and Savage swamp are two swampy biomes generated in the overworld.
Plains biomes with new structures
Sky ruins and Fire plains are plain biomes, with a sky temple structure added to the sky ruins.
Night and day mob spawns
Will-o-wisps and fireflies spawn at night, and mosquitoes spawn during the day; wisps can be caught with a lantern.
Vanilla mob variants
Existing vanilla mobs gain new variants that appear in the added biomes and elsewhere in the overworld.
Ambient terrain features
Floating islands, crystals and giant plants add unusual scenery to the generated world.
