Thirty HDRI maps from Poly Haven (CC0), grouped by the kind of light you’re actually trying to achieve. No more browsing through hundreds of thumbnails trying to guess which one gives you soft studio lighting. Four groups cover the scenarios you’ll need most: studio softbox (product shots, hero renders), golden hour (warm exteriors, architectural flythroughs), overcast diffuse (soft even light for material previews and character work), and night cinematic (moody dramatic lighting for game environments and film).
Every HDRI comes in 16K resolution as both .hdr for real-time engines and .exr for offline rendering and compositing. The lighting reference PDF is the killer feature here — each map applied to a chrome ball and a gray sphere with exposure and rotation notes. You can pick the right environment in seconds without loading a single one into your renderer.
