# Environment Profiles

Environment profiles control the default look of a world: sky, fog, ambient light, exposure, tone mapping, lighting preset, and post preset.

## Built-In Presets

Gessa ships six presets:

- Studio
- Outdoor Day
- Outdoor Sunset
- Indoor
- Night
- Stylized

Studio is the default for fresh 3D projects. It uses ACES tone mapping and neutral lighting so PBR materials read correctly before creator tuning.

## Authored Source

World metadata owns the authored `WorldEnvironmentProfile`. Runtime projection resolves it into `SceneSnapshot.environment`, and `RenderEngine` applies it. Cameras can override tone mapping, exposure, anti-aliasing, color grading, vignette, and post preset.

## Tone Mapping

Supported modes are ACES, AgX, Reinhard, Neutral, and Linear. ACES is the default policy. AgX is available for stylized or high-dynamic-range scenes that need a different shoulder and color response.

## Sky And IBL

The visible sky and image-based lighting map are separate. A world can show a color, gradient, skybox, or HDR-style environment while also using an environment map for PBR reflections.

Reflection probes can be added for local box or sphere reflections. Probe baking is editor-driven and stores the baked cubemap strip as a texture asset.
