67 published HDRIs at HDRI Hub carry the sunny tag, priced $8 to $99, at resolutions from 6144x3072 to 16000x8000. Each shows direct sunlight with a visible sun disc and a hard shadow, so the sun's height in the panorama sets both the shadow length and its direction. They suit exterior renders where the shadow pattern is part of the composition.
















































HDRI Hub lists 67 published sunny HDRIs, priced $8 to $99, at resolutions from 6144x3072 to 16000x8000. Examples include HDR 106 Dawn, with a low morning sun; HDR 013 Harbor 1, a harbor scene under direct light; and HDR 019 Forest 1, a forest clearing with dappled sunlight.
Shadow length depends on the sun's elevation angle: at 45 degrees a shadow equals the object's height, and it grows past 5 times that height once the sun drops to around 10 degrees, as at early morning or late afternoon. An unclipped sunny HDRI keeps the sun's actual brightness in the file rather than clipping it to white, so shadows stay sharp and correctly scaled instead of soft-edged. Rotate the file on its vertical axis to move the sun's direction without changing the elevation baked into that file.
