AI HDRI Generator

HDRI Sphere & Skybox Generator for Environment Maps

It produces a 2:1 equirectangular environment from text or image guidance, lets you inspect the full wrap in a 360-degree viewer, and exports image or HDR assets plus six-face engine packs for Unity, Unreal Engine, Godot, Roblox, and Three.js.

What does the AI HDRI Generator produce?

Generate 2:1 panoramic HDRI-style environments from text or images, inspect them in a 360° viewer, and export panoramas or engine-ready cubemap packs.

2:1Equirectangular panorama for environment-sphere workflows.
360°Rotate through the horizon and full wrap before export.
5 enginesUnity, Unreal Engine, Godot, Roblox, and Three.js packs with selectable square face sizes.

Output boundary: The generated environment is a creative lighting asset, not a calibrated real-world light probe. Validate exposure, color response, and reflection behavior in the target renderer.

What changed

  • Added a precise output definition below the existing tool presentation.
  • Added target and face-size selection for engine-ready cubemap handoff.
  • Added target-specific face labels, manifests, setup scripts, and photometric calibration limits.

SituationChooseWhy
The scene needs a new sky or lighting direction. Generate an HDRI sphere Create the panoramic environment from text or a visual reference.
The horizon or seam is uncertain. Use the 360° viewer Inspect orientation and wrap from inside the environment.
The target reads equirectangular maps. Export an image or HDR Use the 2:1 panorama directly, choosing an AI upscale only when you need the plan-allowed output: up to 8K on Creator or 16K on Studio.
The target requires six cubemap faces. Export to engine Choose the engine and square face size; PLAYTEX AI packages the named faces, manifest, and setup instructions.

Scope and limitations

The generated environment is a creative lighting asset, not a calibrated real-world light probe. Validate exposure, color response, and reflection behavior in the target renderer.
