Streams don't just expose raw stone. Each channel is "skinned" in three zones: the bed (under the water), the waterline, and the cut bank above, with biome-appropriate materials.

• Sensible defaults out of the box: gravel beds + grassy banks, sandy banks in deserts/badlands, raw stone in mountains and cliffs (including Terralith's granite/basalt cliffs), and more.
• Fully customizable. Define your own bank styles: materials per zone, targeted by exact biome or biome tag, with an exclude list ("all overworld but not frozen"), adjustable waterline width and edge blending, or disabled entirely for a given biome.
• Add styles two ways: drop JSON in the config folder for your own game, or ship them in a datapack/addon. The mod seeds a README and examples/ folder on first launch.

• Bank flora: extra grass, ferns, and flowers dress the waterline, with configurable density (and a radius that fades out from the water).
• Biome-boost: near the water, and configurably- the mod can re-run a biome's own plants and rocks so the waterline looks native to wherever you are: lush jungle undergrowth, desert shrubs, mountain boulders. You can blacklist any feature you don't want crowding the banks (vanilla pumpkin patches are excluded by default).
• Bank Features: plant your chosen features: reeds, bushes, even trees right along the banks, targeted by biome, via config folder or datapack. Ships empty; add what you like.

• Waterfalls churn. Falling water throws white spray and soft foam that scales with the height of the drop.
• Whitewater at the details: water flecks a little spray wherever it steps down even a single block, at the lip of every drop, and along seams where a stream meets a wall, a drop edge, still water, or a stream turning a different way. Froth appears naturally at bends and confluences.
• On vanilla water too: rivers, lakes, and vanilla waterfalls get the same treatment, not just the mod's own streams (toggle with particlesOnVanillaWater).
• Distant waterfalls froth far past the ~16 blocks the game animates around you, out to a configurable range, with level-of-detail so faraway falls stay cheap.
• Gentle surface bubbles drift on calm water.

Small leaves (tinted to the local foliage colour) and the occasional forked wooden twig drift downstream with the current, lying flat on the water: a subtle touch of life on the surface. Uses the mod's own textures, so it shows on every supported version. Toggle with streamDebris.

Turn on rebiomeStreams and carved streams are stamped as minecraft:river after they generate so they read as rivers for water colour, fish/mob spawns, and ambience. It runs as the very last worldgen step, so it never changes what the surrounding biome placed. New chunks only.

• Every feature can be toggled or tuned: flow, boats, vegetation, particles, debris, banks, the works.
• Quality presets from Potato to Max (see below).
• Settings are split into a worldgen/gameplay file and a client rendering file, so dedicated servers never load the client one.
• Fine dials for wetness (how much water the land carries), stream width and meander, appearance, and performance.

On the default performance settings when creating a new world, Streams Reflowing needs to query terrain height across the spawn area before it can place streams. During this process, the loading bar may appear stuck at 0% for a minute. This is completely normal. Once the world opens for the first time, you may notice initially slow chunk loading while height data is queried. This is also normal and will resolve after the first couple minutes of playtime.

Players moving quickly through unvisited regions may encounter unrendered chunks while the mod catches up with terrain queries. Slowing down or pausing in place will allow chunks to finish generating. For the smoothest experience, we strongly recommend pregenerating your world with Chunky before playing. Or try lowering your performance preset in the config if you run into hitches.

Streams Reflowing includes quality/terrain accuracy presets in the config ranging from Potato to Max. These control how accurately streams follow natural terrain waterflows and how far watersheds extend across the landscape. If you plan to pregen your world with Chunky, consider bumping up your quality preset. You'll get streams that trace the terrain's natural waterflows much more faithfully, with no runtime cost once generation is complete.
