Realtime River Generator v1.3.1 for Blender — Create Procedural Rivers With Ease

Building realistic rivers, streams or flowing water in Blender can be time-consuming: setting curves, building terrain, matching displacement, adding foam and flow maps. Realtime River Generator simplifies this by giving you a geometry-nodes-based addon that configures a river mesh, ground displacement, foam generation and more — all designed to work in both Eevee and Cycles.

What the Add-On Does

Lets you draw a curve or guide for the river path and the addon builds the river mesh along it, automatically deforming terrain (or displacing ground) to accommodate the river channel.
Generates foam along banks and around rocks automatically when used with the built-in shader / geometry-node setup. Users note “the shader is very impressive, generating foam automatically from edges and around the rocks”.
Geometry nodes harness: Because it’s built with geometry nodes it updates in real-time viewport (to an extent) and supports modern Blender versions (3.3+).
Works for both Cycles and Eevee render engines, offering flexibility depending on your project’s needs.
Version 1.3.1 indicates this is a matured version with likely bug-fixes, optimisations and additional control compared to early versions (though specific changelog details beyond “works with Blender 3.3+” are limited in public listing).

Key Features & Highlights

Curve driven river path: Draw or place a curve path, then let the addon build the river geometry along it — saving modelling time.
Ground displacement algorithm: Automatically displace surrounding terrain mesh so the river lies naturally rather than just floating above or intersecting crudely. The addon mentions “better ground displacement algorithm”.
Automatic foam generation: Built-in shader or geometry nodes for foam around banks/rocks, giving believable water interaction without manual texture painting.
Real-time preview: You can iterate quickly thanks to the geometry nodes setup.
Render engine support: Works in both Eevee and Cycles, making it versatile for production or faster previews.
Blender version compatibility: Supports Blender 3.3 and above.
User feedback: Users have rated it ~4★ for the initial version, praising ease of use and potential.

Why It’s Useful

Drastically reduces modelling time: Instead of manually modelling river banks, terrain indentations, foam textures and flow maps, you let the addon handle much of it — freeing you to focus on lighting, composition and environment.
Streamlines environment scene creation: Rivers are common in environment art (nature scenes, game levels, VFX). This tool gives you a ready base so you can build around it.
Allows rapid iteration: Because it’s procedural, you can adjust path/curve and see immediate changes. That helps when you’re iterating layout or trying different flows.
Good for both still and animation: If you’re rendering stills or animating river flow, the node setup gives you flexibility.
Works on modern pipelines: Compatible with newer Blender versions, geometry nodes workflows, both major render engines — makes it production friendly.

Ideal Use Cases

Nature environment scenes in Blender: rivers winding through terrain, forest scenes with water features, game environments with flowing water.
Cinematic or still renders where a realistic river adds atmosphere: game concept art, illustration renders, background environments.
Game asset creation: build terrain + river segments for level design or modular river components.
VFX plates or backgrounds: realistic river geometry and shader for visual effects contexts.
Quick prototyping of terrain/layout: you can mock up rivers rapidly for location blocking before detailing.

Things to Consider / Caveats

Although the addon handles a lot, you still need good base terrain topology and reasonable scene scale — if your terrain is too low resolution or too small, distortion may occur.
Some user feedback noted limitations such as foam control, rock placement, or river intersection issues: > “Could be improved… If we could play on the transparency of the water or on the parameters of the foam… but it’s really very good!”
Procedural tools can sometimes produce generic output—customising materials, adding variation, and refining details will still be important to avoid “stock” look.
Performance: large terrain + river + foam + rocks can stress viewport FPS in Blender, especially in Eevee with many assets. Optimisation will still matter.
Since version 1.3.1 is relatively recent, ensure your pipeline (addons, nodes, materials) is up to date and compatible.
While it automates many tasks, you may still want to manually refine flow directions, turbulence, banks, vegetation and textures to match your vision.

Final Thoughts

Real-time River Generator v1.3.1 is a well-designed, efficient tool if you’re working in Blender and need convincing river geometry with fast iteration. It bridges the gap between basic terrain modelling and detailed river scene setup by automating crucial parts of the workflow—making it a smart addition for environment artists, game level designers, motion artists or illustrators.

If you often find yourself modelling rivers by hand or spending too long on terrain + water interactions, this addon will save you time and give you a solid foundation to build around. It won’t replace the need for lighting, vegetation, environment detail and artistic polish—but it gets you 60-70% of the way there quickly.
