This is a collection of high dynamic range (HDR) EXR equirectangular environment maps designed for 3D product lighting and surface reflection analysis. The maps provide seamless 360-degree environment mapping and capture full light intensity to help achieve realistic ambient lighting. They are also useful for analyzing material reflections and surface details during the modeling process.

The maps are provided in 3840x2160 resolution in the OpenEXR format and were procedurally generated using Blender and Cycles. The package includes preview thumbnails showing how each map illuminates a mirrored sphere to assist in comparing lighting effects. Because the maps are standard EXR files, they are compatible with any 3D software or rendering engine that supports environment mapping.
