SkyGen LITE is a Godot 4 editor dock that generates seamless equirectangular skybox textures. There is no painting, no HDRI and no shader to write: pick a preset, move a few sliders, press Generate, and you get a PNG plus a ready PanoramaSkyMaterial in your project.

What it makes:

• Gradient skies with zenith, horizon and ground colours and a curve control.
• A sun with disc size, colour, glow radius and strength, at any azimuth and elevation.
• Stars placed evenly on the sphere, seeded, with a small cross on the brighter ones.
• Three presets: Clear Day, Golden Sunset and Starry Night.
• Output from 256 to 1024 pixels wide (height is always half), 8-bit PNG, seamless at the wrap edge.
• The same seed and settings always give the same sky; Random seed rolls a new one.

How it works:

• Copy addons/skygen into your project and enable the plugin in Project Settings > Plugins. The SkyGen dock appears next to the Inspector.
• Preview renders a 512 px version in well under a second. Generate and save writes the full-size PNG and a _sky.tres PanoramaSkyMaterial that you drag into a WorldEnvironment.
• The generator is one GDScript class (SkyGenCore) with no editor dependency, so you can also call it from your own tool scripts or at runtime for procedural skies per level or per seed. The README shows the three lines it takes.

Compatibility: Godot 4.2 to 4.5, any renderer (Forward+, Mobile, Compatibility). Pure GDScript, no GDExtension. Generation runs on the CPU: about a second for a 1024 x 512 sky.
