Why River

Turn waterways into complete environments.

A convincing river needs more than a water plane. River gives the shoreline, wetland vegetation and surrounding terrain a procedural structure so the whole corridor reads as one connected biome.

01 / ECOSYSTEM

Generate the environment around the water.

Build riverbanks, wet areas and surrounding vegetation as part of the same workflow instead of dressing every shoreline manually.

02 / VARIATION

Keep long waterways from repeating.

Procedural placement creates natural changes in density, foliage and edge composition as the river moves through the landscape.

03 / SCALE

Use one workflow across large worlds.

Create river corridors that can pass through forests, meadows and open terrain while remaining editable as the level evolves.

Production toolset

Procedural tools for rivers, banks and wetlands.

River combines PCG environment generation with water-focused vegetation rules and terrain-aware placement for large natural landscapes.

PCG

Procedural river ecosystem

Generate the surrounding environment with editable PCG rules instead of hand-authoring every stretch of riverbank.

BNK

Natural riverbanks

Build convincing edge transitions with vegetation and terrain-aware placement around the water corridor.

WET

Wetland variation

Blend marshy and water-adjacent vegetation into the river environment for more believable lowland areas.

BIO

Biome integration

Let waterways pass naturally through forests, fields and other EasyBiomes environments without feeling disconnected.

EDT

Editable workflow

Keep tuning placement and density as the terrain, river path and surrounding level design change.

OW

Open-world ready

Scalable procedural placement is designed for long river corridors in large streaming environments.

Production scale

Designed for long, connected waterways.

The system is built around river corridors that need to remain coherent over distance while still adapting to terrain, biome transitions and local environmental variation.

Actual performance depends on water setup, vegetation density, active foliage systems, shadows and project configuration.

01 / ECOSYSTEM

Make the banks part of the biome.

Vegetation, wet areas and shoreline structure work together so the river feels integrated into the landscape rather than placed on top of it.

River workflow
02 / SCALE

Carry believable variation over distance.

Procedural rules make long river corridors easier to build without repeating the same manually dressed bank treatment.

River workflow
03 / INTEGRATION

Connect multiple landscape types.

Use the river as a natural transition through forest, meadow, wetland and other EasyBiomes environments.

River workflow
EasyBiomes ecosystem

Let the river connect the world.

Use River between forests, farmland and open landscapes to create natural corridors that visually tie multiple biomes together.
