## Supported formats

- GLB / GLTF

## Features

**HDRI environment lighting** - Choose from several environment maps to see how your model looks under different lighting conditions. The HDRI provides realistic reflections on metallic and glossy surfaces.

**Material inspection** - View individual material channels including albedo, normal map, roughness, and metallic. This helps you verify that textures exported correctly.

**Screenshot export** - Capture a high-resolution screenshot of your current view. Useful for sharing previews or creating thumbnails.

**Orbit, pan, and zoom** - Left-click to orbit, right-click to pan, scroll to zoom. The viewer centers automatically on your model.

## Privacy

All processing happens locally in your browser. Your files are not uploaded to any server. This makes the viewer suitable for confidential or pre-release work.
