Skybox Mod for STRAFTAT

Replaces the skybox on every map with your own 360° images. Pick a skybox from a dropdown in ModMenu's settings panel. Vanilla compatible — purely client-side, other players see vanilla.

Make your own skybox

Open BepInEx/plugins/SkyboxMod/templates/Template.png in any image editor (GIMP, Photoshop, Krita, Paint.NET, Aseprite — anything). It's a 4096×2048 labeled canvas with the horizon, zenith, nadir, cardinal directions, and a grid drawn on it so you can see where everything will land on the sphere.

Paint over it however you like, then save it as .png or .jpg directly into BepInEx/plugins/SkyboxMod/ (any name you want). Restart the game and it shows up in the dropdown.

Use existing 360° images

You don't have to draw from scratch — drop any equirectangular .png / .jpg / .jpeg file into BepInEx/plugins/SkyboxMod/ and it shows up in the dropdown. Filename (without extension) is what you'll see.

Good free sources:

• Poly Haven Skies — CC0 daytime/sunset/overcast skies. Use the "Tonemapped JPG" download.
• Poly Haven Night HDRIs — CC0 starscapes and urban night.
• ESO Image Gallery — astrophotography under CC BY 4.0.
• NASA Photojournal — public domain space imagery.
• A 360° photo from your phone's panorama mode also works.

The image must be equirectangular (2:1 width-to-height ratio, e.g. 2048×1024, 4096×2048, 8192×4096). The bundled skyboxes are 4096×2048 — that's twice the base game's resolution.

Caveats

• New files require a game restart to appear in the dropdown — ModMenu caches the dropdown options the first time the settings panel opens.
