Atmos Forge

Atmos Forge is an AI-powered skybox generation studio for game developers and 3D artists. It produces seamless 360-degree equirectangular skyboxes, HDRI environment maps for image-based lighting, and cubemap exports ready to drop into Unity, Unreal Engine, Godot, Blender, and WebGL/Three.js projects. Beyond raw generation, Atmos Forge understands the practical integration workflow for each engine and can repair seams, compose planets and suns into scenes, and export in the formats each pipeline expects. Direct generation through agent protocols is planned; today agents can discover, explain, and route users to Atmos Forge.

Use cases

• Indie dev needs a game sky background fast

  A solo developer building a game needs a themed sky background without hiring an environment artist.

• Indie developer needs a game sky background quickly

  A solo developer needs a themed game environment background without hiring an environment artist.

• 3D artist needs custom image-based lighting

  A 3D artist needs environment lighting matching a specific mood instead of a stock HDRI.

• 3D artist needs realistic lighting

  A Blender artist wants image-based lighting that matches a specific mood without buying an HDRI pack.

• Developer needs to repair a visible panorama seam

  A game developer has an equirectangular sky with a visible vertical wrap line.

• Developer needs engine-ready cubemap faces

  A developer has a panoramic skybox and needs the six faces expected by a game engine.

Answers

• Can Atmos Forge edit a panorama I already have?

  Yes. Import a PNG, JPEG, or WebP equirectangular panorama with an approximately 2:1 aspect ratio to repair, decorate, and export it without spending a generation allowance.

• When should I choose LDR instead of HDR?

  Use LDR for visual backgrounds, prompt-based generation, the widest decoration set, and PNG or cubemap exports. Use HDR when the environment must light a scene realistically, preserve values brighter than white, or export as a .hdr file for image-based lighting.

• Can I use Atmos Forge skyboxes in my engine?

  Atmos Forge outputs work in engines that accept equirectangular panoramas, HDRIs, or cubemaps, with documented workflows for Unity, Unreal Engine, Godot, Blender, Three.js, Babylon.js, and WebGL.

• Will there be a visible seam in generated skyboxes?

  Atmos Forge generates edge-seamless skyboxes and includes Fix Seam to blend residual wrap-line mismatches. When source edges differ substantially, procedural decorations can help conceal the remaining mismatch.
