3DT Coral Reef Generator – Blender Geometry Node Procedural

🎥 Demo Video

Design detailed underwater coral scenes in seconds using the 3DT Coral Reef Generator!

Optimized for Blender 4.0+, this procedural node system includes two Geometry Nodes — one for coral generation and one for coral scattering — along with stylized materials, prebuilt collections, water shaders, and full compositing setup to achieve cinematic reef scenes instantly.

🎯 Key Features

Dual-Node Coral and Scattering System
Generate stacked coral formations using curve-based base mesh and scatter 60+ included coral types across tops, walls, and sand.

Real-Time Density, Layer, and Radius Control
Easily tweak layer count, height randomness, displacement strength, and object radius from node sliders.

Collection-Driven Asset Swapping
Load in any coral, kelp, seaweed, or crustacean collection to replace included assets for infinite reef variation.

Built-In Stylized Materials
Pre-applied coral, sand, and shell materials ready to render — plus material swapping support for your own shaders.

God Rays and Water Shader Setup
Achieve stunning underwater lighting instantly with included water shader and compositing node pre-setup.

🔥 Why You'll Love It

Instant Coral Reef Scenes
Generate underwater compositions in minutes instead of sculpting or placing dozens of assets by hand.

Perfect for Games, Cinematics, and Concept Art
Fill seabeds, temples, shipwrecks, or fantasy zones with believable reefs and ocean floor details.

Auto-Density Logic with Seed Variation
Prevents overlapping scatter by automatically checking for collisions and adjusting placement with each seed.

Viewport-Optimized and Beginner-Friendly
Quick preview, low impact on performance, and simple one-click setup makes this ideal for fast production.
