Streams get proper banks instead of bare stone. Each bank style is a set of rings running out from the water: the bed, the waterline, the bank, and an optional second bank ring. Ring sizes scale with the stream, so a wide river gets wide banks and a small brook gets narrow ones.

• Good defaults out of the box: gravel beds and grassy banks, sand in deserts and badlands, sandy beaches, and bare stone in mountains and cliffs (including Terralith's).
• Mix several blocks in a ring and they come out in natural patches. A style can also switch blocks where a stream is steep, fast, bending, near its mouth, or running flat for a long way.
• Pick styles by biome or biome tag, exclude the ones you don't want, or turn banks off for a biome.
• Add your own styles in the bank_styles config folder or ship them in a datapack. The folder includes a GUIDE.md and examples, and styles made for older versions still work.

• Bank plants: extra grass, ferns and flowers along the water, thinning out as you move away from it. You can set how dense they are.
• Native plants: near the water, the mod can re-run the biome's own plants and rocks, so the banks look like they belong: jungle undergrowth, desert shrubs, mountain boulders. Anything you don't want on the banks can be blacklisted (pumpkin patches are off by default).
• Scenery in the rings: a bank style can place things on any of its rings: seagrass and kelp on the bed, lily pads at the waterline, plants along the bank.
• Your own features: add reeds, bushes, fallen logs or even trees along the banks, by biome, from the config folder or a datapack. A style can also call them into one of its rings.

• 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.
