Autokelp 3.0!

Fully animated and customizable

Autokelp is a procedural underwater environment tool built for Blender users who want to create kelp forests, ocean scenes, and animated marine setups with more control and less manual assembly. Instead of working from a single static plant asset, you get a scene-building setup that helps you shape foliage, motion, and water presentation as part of one underwater workflow.

The interface is designed to stay simple while giving you detailed control over the look of your foliage. Leaves can be adjusted for density, size, direction, color, and opacity, making it easier to push the setup toward different scene moods and compositions. With 15 leaf presets included, you can move quickly from broad layout work into more refined visual variation.

Animation is built into the setup in a practical way. Kelp stems are animated with a wave modifier, while leaves are animated directly through Geometry Nodes. Fish also follow foliage movements while swimming, helping the environment feel more connected and alive in motion rather than behaving like separate isolated elements.

Includes everything you need to create and edit a full, custom underwater scene.

Fine-tune the leaves with a variety of detailed controls:

Size

 Direction

Color

The included water environment expands this from a foliage generator into a more complete underwater world-building tool. It includes six presets and supports scenes above water, below water, or shots that split the waterline. Animated reflections on the water surface add extra movement and fine detail when viewed from below without increasing vertex count, helping you create more dynamic water presentation from multiple viewing angles.
