Screenshots

Installation

• Clone or download the repository.
• Open the project in Godot and run demo/Sky3DDemo.tscn to test it.
• Copy addons/sky_3d into your project addons directory. Create the folder if missing.
• Open Project -> Project Settings -> Plugins and enable the plugin.

Usage

• Create or open a Scene.
• Remove any existing WorldEnvironment node.
• Create a new Sky3D node.
• Customize the settings of the Sky3D, Sky3D/Environment, TimeOfDay, SkyDome, SunLight, and MoonLight nodes. Some settings like light energy, color, and angle are driven by Sky3D and not directly changeable on the light nodes. You'll know if they are reset on time updates. Adjust those settings in Sky3D or SkyDome.

Compatibility Renderer Note

This render needs a bit of adjustment to show similar results to Vulkan:

• Sky3D / Sky Contribution = 0.75
• SkyDome / Fog / Fog Density = 0.01

Documentation

The documentation is built in to Godot. Look for tooltips in the inspector where available, or press F1 and search for Sky3D, SkyDome, TimeOfDay.

And all of the wonderful contributors shown in the right sidebar of the github repository.

The original version of this plugin, TimeOfDay v1, was made by J. Cuéllar for Godot 3. You can find it in the godot3 branch. The original repository was deleted. We revived it, ported the GDScript version to Godot 4, and have continued to build on it to produce Sky3D.
