I publish NebulaKit. This is one complete free, static HDR space environment for an existing Godot 4.5 3D scene: a 2048 x 1024 linear half-float EXR, matching Sky and Environment resources, a one-node WorldEnvironment scene, import settings, provenance and licences.

Download page → Download demo → FREE Godot 4.5 HDR resource kit — complete Deep Field 11 environment. The ZIP is 6,918,425 bytes. The page also offers a paid full twelve-sky kit; this one-sky resource is complete and requires no purchase.

Import into your scene

  1. Copy the extracted nebula_skies folder into your project root, keeping res://nebula_skies/....
  2. Let Godot finish importing. For the EXR, keep HDR as sRGB off, HDR compression disabled, and mipmaps on; the README lists all supplied import settings.
  3. Use a scene with a current Camera3D and only one active WorldEnvironment for its World3D. Instance nebula_skies/worlds/deep_field-11.tscn, or assign nebula_skies/environments/deep_field-11.tres to your existing WorldEnvironment.
  4. Run your scene. The paired Environment already includes the source-orientation correction. Adjust sky brightness, exposure and ambient energy to suit your materials and lighting.

Deep Field 11 in the actual Godot static-resource test

Actual Godot 4.5 Compatibility capture on Windows / Intel Arc 140T. The plane, three spheres and camera are test fixtures and are not included. This image demonstrates the supplied environment, not a playable scene.

This is a static resource kit, with no scripts, sky-switching controller, standalone project or telemetry. The released resources passed the documented finite import/runtime test on that host; other versions, renderers, GPUs, mobile devices and long sessions are unverified.

The sky artwork comes from the studio’s procedural volumetric pipeline. Resource setup, conversion/verification scripts and writing were AI-assisted; no live AI is used. Image data uses the included royalty-free finished-project licence (commercial game use allowed; no raw/derived stock redistribution); resource definitions and documentation use MIT.

If you try it in an existing scene, a useful voluntary report is your Godot version, renderer, whether the sky appears, and the first import step that did not work. No personal information is needed.
