AI Skybox Generator
Generate game-engine-ready skyboxes from a text prompt. Equirectangular 2:1, seamless wrap, free trial.
Built for game engines
Game-engine-ready 2:1 equirectangular
Drop straight into Unity (Skybox/Panoramic shader), Unreal Engine (HDRIBackdrop), or Blender (Environment Texture). No format conversion needed.
8 game scene presets
Sci-fi space station, fantasy castle, cyberpunk street, post-apocalyptic wasteland, underwater ruins, alien planet, mountain valley, mecha hangar — picked for the most common game environment archetypes.
Seamless 360° wrap
Our prompt rewriter asks the model to connect the left and right edges. This guides generation but does not guarantee an invisible seam. Inspect the result through a full rotation before using it as a skybox.
Powered by GPT-image-2
Built on OpenAI's latest image model (the same engine behind ChatGPT image generation). Specialized for panoramic output.
Convert to cubemap
Generated a panorama? Convert it to 6 cube faces in one click for legacy Unity pipelines and cube-based Three.js workflows via our Cubemap Generator.
Commercial license
Every paid plan and credit pack includes full commercial use rights — ship in your game, on Steam, on consoles.
From prompt to engine in 60 seconds
1. Describe your scene
Pick a preset or write your own 10-30 word prompt. Style modifiers (cyberpunk, fantasy, sci-fi) work great.
2. Generate at 1K, 2K, or 4K
1K for fast iteration, 2K for web, 4K (3840×1920) for VR or detailed engine scenes.
3. Preview in 360°
Inspect the result in our embedded viewer before downloading. Catch seam issues early.
4. Drop into your engine
Unity, Unreal, or Blender — copy-paste setup below. Convert to cubemap only if your pipeline needs 6 faces — Unreal and Blender take the panorama directly.
Drop into your engine
- In Unity, drag the downloaded PNG into Assets. Set Texture Type to Default, Wrap Mode to Clamp, Filter Mode to Bilinear.
- Create a new Material (Assets → Create → Material). Set its Shader to Skybox/Panoramic.
- Drag the panorama texture into the material's Spherical (HDR) slot.
- Open Window → Rendering → Lighting → Environment. Set Skybox Material to your new material.
- Click Generate Lighting to update GI.
// Assign at runtime (optional)
using UnityEngine;
public class SkyboxLoader : MonoBehaviour {
public Material skyboxMaterial;
void Start() {
RenderSettings.skybox = skyboxMaterial;
DynamicGI.UpdateEnvironment();
}
}Example generations
Sci-fi Space Station
Prompt
futuristic orbital space station interior, panoramic windows, planet outside, polished metal walls, cinematic game lighting
AI Skybox vs HDRI Haven vs Asset Store
When to use each
| Feature | AI Skybox Generator | HDRI Haven | Asset Store |
|---|---|---|---|
| Custom subject | Anything you can describe | Their library only | Their library only |
| Generation time | 30-60 seconds | Browse + download | Browse + purchase + download |
| Commercial license | Included (Pro plans) | CC0 (free) | Varies by listing |
| True HDR (32-bit) | No (LDR source) | Yes | Some |
| Cost | $0 trial, then subscription | $0 | $5-50/asset |
Use HDRI Haven for free real-world environments. Use Asset Store when you need stylized scene-specific kits. Use AI Skybox Generator when you need a specific, custom-described scene that doesn't exist in any library.
A Skybox AI alternative for Unity, Unreal, and Blender
If you landed here looking for a Blockade Labs Skybox AI alternative, here is the honest comparison. Blockade Labs built its own generation model, exports up to 8K, and ships a matching depth map — genuinely useful if you need parallax or extra pixel density. We do not match those three things.
What we do differently: generation runs on GPT-image-2 at 1K, 2K, or 4K, and every output is a 2:1 equirectangular PNG that drops straight into a Unity Skybox/Panoramic material, an Unreal HDRI Backdrop, or a Blender Environment Texture. If your pipeline still needs six faces, the Cubemap Generator slices the result in your browser — no re-upload. When you need image-based lighting rather than a backdrop, the AI HDRI Generator writes the same view into a Radiance .hdr container. Credits include a commercial license, and a free trial covers one full generation.
Choose Skybox AI when 8K resolution or a depth map is a hard requirement for your scene. Choose this skybox generator when you want a specific described environment as an engine-ready 2:1 file, a cubemap in the same session, and an HDRI path for the moments when lighting matters more than the view behind it.
Need 6 cube faces instead?
Convert your skybox to a 6-sided cubemap in our Cubemap Generator — runs in your browser, no upload, free.
FAQ
Can I use the generated skybox commercially?
Yes — every paid plan and credit pack includes a full commercial license. Ship in your game on Steam, consoles, mobile stores, or as part of a paid Asset Store listing.
What resolution should I use for mobile VR?
2K (2048×1024) is the sweet spot for Meta Quest 2/3 — it looks sharp without exceeding mobile GPU texture limits. 4K (3840×1920) is fine for Vision Pro and high-end PC VR but may be overkill on standalone Quest.
Does it work with URP / HDRP / Built-in pipeline?
All three. URP and HDRP both ship with Skybox/Panoramic shader support. Built-in pipeline uses the same shader. For HDRP IBL contribution, use the Sky and Fog Volume → HDRI Sky override pointing to the same texture.
Will my skybox have a visible seam?
A visible seam is possible. The prompt asks the model to align the left and right edges, but results vary. Inspect the skybox in the viewer; if the boundary is noticeable, simplify the prompt and generate again.
Can I generate cubemaps directly?
Not yet. Generate a panorama first, then convert to cubemap in your browser in one click — no re-upload, no API cost.
Is this the same model as ChatGPT?
We use OpenAI's gpt-image-2 — the latest image model behind ChatGPT's image generation. We specialize the prompt for equirectangular 2:1 panoramic output and verify wrap-around quality. We are not affiliated with or endorsed by OpenAI.
How is this different from Blockade Labs Skybox AI?
Different image model (we use GPT-image-2; they use their own). Different pricing tiers. Different feature set — Blockade Labs has 8K and depth maps; we have lower starting price and prompt-driven cubemap conversion in the same workflow. Pick whichever fits your project budget and resolution needs.
Can I export as HDR for IBL lighting?
Yes — use our dedicated AI HDRI Generator. It outputs the same 2:1 equirectangular panorama wrapped in a Radiance .hdr container, suitable for Blender Cycles, Unreal HDRI Backdrop, and Unity HDRP environment lighting. Honest note: source is 8-bit LDR; we don't fake true 32-bit HDR.
