Godot Infinite Grid

Description

Godot Infinite Grid is a lightweight addon for Godot 4.x that provides reusable infinite grid components for both 2D and 3D scenes.

It is designed for editor-style tools, level editors, strategy views, debug scenes, prototyping environments, and any project that needs a clean grid that feels endless without generating huge geometry.

The grid is shader-driven, keeps line widths stable in screen space, smoothly fades between LOD levels, and follows the active camera so it remains useful while panning, zooming, or moving through the scene.

Included components

• InfiniteGrid3D An editor-style XZ ground grid for Camera3D scenes.
• InfiniteGrid2D A full-viewport grid for Camera2D scenes.

Features

• Works with Godot 4.x
• 2D and 3D infinite grid scenes included
• Screen-space line width and anti-aliasing
• Smooth decimal LOD transitions
• Camera-following behavior
• Configurable cell size, colors, opacity, and LOD settings
• Debug LOD coloring
• No external runtime dependencies
• No plugin activation required

Quick use

Copy the addon folder into your Godot project:

res://addons/infinite_grid/ 

Then instance one of the reusable scenes:

res://addons/infinite_grid/infinite_grid_3d.tscn res://addons/infinite_grid/infinite_grid_2d.tscn 

For 3D scenes, add InfiniteGrid3D to a scene with a Camera3D.

For 2D scenes, place InfiniteGrid2D inside a CanvasLayer and use it with a Camera2D.
