Godot SceneBuilder: Supercharge Your 3D Scene Creation!

#godot #addon #gamedev #3d

Hello 👋

I’m excited to share Godot SceneBuilder — a powerful addon for Godot 4 that revolutionizes how you work with 3D meshes. Whether you’re building vast environments or intricate structures, this tool will save you time and boost performance.

What Does It Do?

SceneBuilder lets you:

Procedurally scatter meshes in circles, grids, or custom patterns.
Create spirals (perfect for staircases or organic structures) with adjustable height, turns, and radius growth.
Merge instances into a single MeshInstance3D using SurfaceTool, drastically reducing draw calls and improving performance.
Extend functionality with your own GDScript algorithms — no core modifications needed!

Why You’ll Love It

Editor-native: Runs entirely within Godot Editor (@tool).
Smart rotation: Align instances to face the center or follow tangents using atan2.
Flexible: Override materials, tweak transformations, and create custom scatter patterns.
Performance-focused: Merging meshes means fewer draw calls — ideal for complex scenes.

Get Started in 4 Steps

Download the repository.
Copy addons/scenebuilder into your project’s res:// directory.
Enable the plugin in Project > Project Settings > Plugins.
Add a SceneBuild node, assign a mesh, pick a pattern (e.g., Circle or Grid), adjust parameters, and click Build!

Go Advanced: Custom Functions

Want unique patterns? Edit ScatterFunctions.gd to define your own logic. Pass arguments directly from the Inspector — supports floats, booleans, and strings. Example:

static func my_custom_shape(amount: int, distance_to_center: float, ...args) -> Array:
    var points = []
    # Your magic here
    return points

Then select Custom in the editor, set your function name, and pass args like true, 5.5, "hello".
