LookDev — Environment

Environment is the HDRI library and preview workspace. It supports local .hdr, .hdri and .exr files together with downloadable Poly Haven environments.

Local libraries

Use + Folder, + File or Scan Drive / Folder. Library paths, categories, favorites and notes are retained between sessions.

Poly Haven

Switch Source to Poly Haven to browse cloud HDRIs. Choose the resolution and format before download. The download destination is configured in LookDev Settings, and completed files are added to the local library.

Find and inspect

Filter by source, category, format, favorites or duplicate filename, then search and sort the visible grid. Selecting a card updates resolution, file size, format, dimensions, category and notes in the inspector.

Realtime Preview Lighting

The preview displays the panorama and selected material balls, tracks HDRI rotation in real time, and can synchronize rotation with the active V-Ray dome while Viewport RT is enabled. The sun marker is estimated from image luminance, not from the filename.
