Free Source Engine Skyboxes

Production-ready skies for Source Engine and beyond

A quieter way to discover skies with mood, light, and room to explore.

Browse a curated collection of dawn haze, storm light, clear noon, and late-evening color, made for Garry's Mod, Team Fortress 2, and Half-Life 2 maps. Each sky ships as a Source-ready VTF set, alongside the original 32-bit EXR it was rendered from.
