UE4 compatible HDRIHaven.com HDRi cubemaps

129+ cubemaps in 1K/2K/4K versions (CC0 license)

Last updated 2018/05/29

The HDRis on HDRIHaven.com are now all free and CC0. They are now Patreon supported so if you like them please support the original creator at https://www.patreon.com/hdrihaven .

I modified the files so they could be imported into UE4 (normally you would get an error), changed the filenames so they are more easily searchable, added some folder organization, then saved the .uasset files as an archive so you can just drop it in a project and not have to waste time fixing the files and importing them.

1k, 2k and 4k files are included. For ambient cubemaps and pure skylights you would use the 1k files. The 2k and 4k files are for reflection cubemaps (you need to increase the maximum resolution in the engine settings), or for lightmap baking in 4.18 with the new skylight cubemap directionality feature. 

UE4 compatible (.uasset) HDRIHaven.com HDRi cubemaps.zip is the .uasset files for dropping in a Content folder.

UE4 compatible (modified .HDR) HDRIHaven.com HDRi cubemaps.zip has the modified .hdr files for modifying them, using in older UE4 versions in case the above don't work, and for model viewer applications (for example cubemaps in Substance).

The naming scheme is CM_(for cubemap)_(Outdoor/Indoor)_(Time of day)_(HDRIname)_(resolution) so for example CM_Ou_Mi_cloudy_vondelpark_1k, meaning Cubemap, outdoor, midday, Cloudy Vondelpark with 1k resolution. This means you can search for just "cm ou" to find the outdoor cubemaps and so on.
