Clipmap3D

A lightweight infinite procedural terrain system for Godot 4.6

Overview

• Written in GDScript, GDShader, and GLSL
• Supports Forward+ and Mobile renderers
• Use a compute shader to generate and texture terrain on the GPU
• No manual work to author terrain; everything is done through code
• Over 30x30km render distance with configurable vertex density and levels of detail (LODs)
• Real-time toroidal LOD shifting as the player moves
• Supports blending up to 32 albedo + normal textures

Roadmap

• Stochastic sampling
• Floating-point origin shifting
• Foliage instancing (scatter system)
• Heightmap image imports and streaming

Limitations

• This project is work-in-progress and is subject to major changes
• Physics interaction is primitive and limited to player collisions
• Image imports are not yet supported

Trying the demos (4.6)

• This repository contains a demo folder with example scenes and compute shaders
  • Erosion terrain demo
  • Simple terrain demo
  • NoLerp demo (For debugging and learning how the clipmap works)
• After loading a scene, set View -> Settings... -> View Z-Far to 16000
• Make edits to the compute shaders in a text editor such as Notepad++ and see changes immediately!
