EXR Environment Maps

EXR Environment Maps Documentation

Overview
This package contains a collection of EXR equirectangular environment maps designed for:
- Product lighting: Achieve realistic ambient lighting in 3D scenes.
- Surface control: Analyze material reflections and surface details during modeling.
- Cross-platform compatibility: Works with any rendering engine that supports EXR format (e.g., Blender, V-Ray, Arnold, Unreal Engine).

Features
✅ High dynamic range (HDR): Captures full light intensity for photorealistic rendering.
✅ Equirectangular projection: Seamless 360° environment mapping.
✅ Preview icons: Small thumbnails show how each map illuminates a mirrored sphere.
⚠️ Rotation sensitivity: Some maps produce drastically different lighting when rotated 90° – experiment for optimal results!

Technical Details
- Format: OpenEXR (.exr)
- Resolution: 3840x2160

Creation process:
- Generated procedurally using Blender + Cycles.

Usage Guide
1. Blender:
- Go to World Properties > Surface > Use Nodes.
- Load the EXR map as an Environment Texture.
- Adjust rotation via the Mapping node for different lighting angles.

1. Other software:
2. Import the EXR file as an environment/skydome texture.
3. Refer to your software’s documentation for HDR lighting workflows.

License & Sharing
- MIT License:
- You can use, modify, and redistribute these maps freely (even commercially).
- Credit is appreciated but not required.
- No warranty: Maps are provided "as-is" – test thoroughly for your use case.

• Included files:
• LICENSE.md (MIT terms)
• EXR maps + preview thumbnails

Tips
- Use the preview icons to quickly compare lighting effects.
- Combine maps with Blender’s Light Path node for advanced material testing.
- For animations, lock map rotation to maintain consistent lighting.
- You can create similar maps by using Blender's lighting setup (mesh lights), environment and compositing node too.
