3DT Island Terrain Generator – Blender Geometry Node Procedural

🎥 Demo Video

Shape epic islands, valleys, and real-time rivers with the 3DT Island Terrain Generator!

Built for Blender 4.0+, this dual-curve geometry node system enables you to sculpt massive islands in seconds, paint detailed rivers, and blend procedural grass, dirt, and stone textures seamlessly — with live viewport editing for optimal performance.

🎯 Key Features

Dual Curve Terrain and River Sculpting
Draw terrain outlines and flowing river paths independently using two editable curve systems with real-time deformation.

Fully Procedural Material System
Auto-blends grass, dirt, and stone based on terrain slope and elevation with adjustable textures, angle limits, and blending intensity.

River Depth and Width Controls
Modify river path width, dropoff height, depth curve, and river floor blending — perfect for customizing different biomes.

Real-Time Mesh Generation
Sculpt in the viewport without baking — instantly update terrains as you adjust curves and painting strokes.

Optimized Viewport and Render Density
Separate settings for viewport performance and final render resolution to allow huge terrains while maintaining speed.

🔥 Why You'll Love It

Fast Landscape Design
Sketch out islands, pen in rivers, and control subdivision, topology, material blending, and mesh optimization within minutes.

Flexible Painting System
Use standard Blender tools to weight paint vegetation areas for future scatter setups like grass, flowers, or trees.

Perfect for Games, Animation, and Worldbuilding
Craft fantasy islands, low-poly archipelagos, realistic canyons, or stylized adventure game worlds easily.

Simple Customization Pipeline
Bring in your own materials, texture maps, or scattering packs — fully compatible with standard Blender workflows.
