HDRI Maker

HDRI Maker provides a procedural workflow to produce environment maps that illuminate 3D scenes without relying on external photography. It targets 3D artists, VFX studios, and product photographers who need repeatable lighting for testing and prototyping. The system accepts structured inputs (resolution, map type, exposure) and returns an HDRI data file plus a preview. It supports multiple presets (studio, outdoor, sunset) and advanced controls (seed, gamma, color balance, roughness, metallic).

Conceptually, the engine treats the environment as an equirectangular panorama, using procedural noise and parameterized lighting probes to fill directions. It applies tone mapping and PMREM pre-filtering to create mip levels for varying roughness, enabling compatibility with modern renderers. The output adheres to the 2:1 aspect ratio typical for HDRIs and carries 32-bit floating point color data per channel.

Beneficiaries include 3D artists, game developers, and product visualization teams. Its unique value lies in deterministic outputs via seeds, diverse presets, and straightforward export paths across HDR/EXR formats. Core features include resolution control, presets, seed-driven determinism, and renderer-ready outputs suitable for lighting tests, asset previews, and rapid iteration. Use cases span character lighting, product shots, and environment testing across multiple scenes.
