Easy River – Stylized Low-Poly River, Lake, Lava & Ice Generator for Blender

Draw a curve, click a button, and get a cute, anime-style low-poly river with a looping flow animation, ready to export to your game engine as a single .glb file. The look is inspired by cozy farming games.

One add-on, four environments

• River: flowing water with flow marks, floating leaves, lily pads, sparkles and splashes
• Frozen River: translucent cracked ice with frozen-in bubbles and snowy banks
• Lava River: glowing lava with dark crust plates, popping bubbles and volcanic banks
• Swamp Lake: murky water with algae, lily pads and gas bubbles

Features

• Build along any curve, or generate a circular river ring or lake with one click
• Swimming fish that also jump out of the water, with splashes
• Looping flow animation that you can rebuild at any time
• Live preview: change a setting and the river updates in the viewport
• Control over width, width variation, seed and colors
• Use your own models for leaves, lily pads, sparkles and fish (up to 3 per type)
• Add your own water texture, with Opacity and Blend control (Mix / Multiply / Add)
• Optional fish-jump sound, played in time with the animation
• Reset buttons for every section, so you can always go back to the defaults

Game engine ready

• One-click Export GLB includes the river and its flow animation
• Seamless looping animation, with adjustable length and FPS
• Also exports the river texture and helper files for scrolling it in game
