Terralith: River In Jungle

RiverInJungle for Terralith is an add-on for Terralith that brings RiverInJungle's wide, winding jungle rivers to Terralith-generated worlds.

Instead of small jungle streams, jungles gain broad, natural-looking rivers with gently sloping banks that blend into the surrounding terrain — in every jungle biome Terralith generates, and the vanilla ones too.

Install on both the client and the server. Works in singleplayer out of the box.

Dependencies: Terralith is required on every loader, for the same Minecraft version (Terralith 2.6+ brings Lithostitched along as its own requirement). Fabric also needs Fabric API and Architectury API. NeoForge also needs Architectury API. Forge needs nothing beyond Terralith.

Free to use in any modpack — public or private, no permission needed.

What it does

• Adds wide jungle rivers — generates long, winding rivers throughout jungle biomes.
• Designed for Terralith — works with Terralith's custom terrain generation instead of vanilla world generation.
• Natural riverbanks — graded shores gradually rise from the water instead of forming abrupt cliffs.
• Varied shoreline materials — banks mix sand, gravel, clay, grass, coarse dirt, rooted dirt, moss, and podzol.
• Lowland only — rivers generate in suitable low jungle areas without carving through mountain slopes.
• Seamless generation — rivers and banks continue smoothly across chunk borders without visible seams.

Details

• Doesn't replace Terralith's terrain — rivers are added after the terrain is generated, so Terralith's landscapes stay intact. Applied automatically to all Terralith jungle biomes, no config needed.
• New chunks only — existing worlds keep their rivers; new ones appear in newly generated jungle.
• Experimental Settings screen — some versions show an "experimental features" or "not supported" message for Terralith worlds. Terralith causes it by itself; this add-on adds no screen of its own.
• Comparing worlds (Fabric) — start the game with -Drij.disable=true to switch the rivers off. Without it, the rivers generate as usual.
