HDRI

List of sites with free HDRi

List of sites with free HDRi

There are links to various HDRIs scattered all over the Iray threads…well, HDRIs aren’t just for Iray. 3Delight, Luxrender, Cycles and Octane all can use them too. Some are in spherical mapping, most are equirectangular/latitudinal-longitudinal mappings…a few are in both, very few are cubic.

Wide quality range
The quality of these will vary greatly, many require a supplemental light source (usually in the location of the sun) to cast ‘hard shadows’…most are non-comm only. (Non-comm = Non-commercial use only, but read the individual licenses on each site/item to be sure.)

Mid to High dynamic range
Most of these are mid to very high range, most will cast decent shadows. Many/most of these will cast ‘hard’ shadows without any additional light sources. Quality and license, noted; ones without comment are either no restrictions or unknown. Many of these sites also have pay versions that range from fairly cheap to rather expensive…but licensing is usually much more ‘commercial’ friendly for the paid versions and there are either higher range HDRs/higher res backplates with the paid ones.

Another source, sometimes even for full versions of some of the high end/price pay-for HDRis…magazines. The included disks/content downloads for many of the computer graphics magazines have offered HDRis at various times. Very often, these are in the high to very high dynamic range categories.
