How to set material as sky

[joseph (J)]

You might be able to… but I doubt it. HDRIs are hard to create even with extremely expensive, powerful, cameras and special tripods. Here’s a note about HDRIs I made earlier. It adds some detail I’m too lazy to re-type

It’s not just about resolution and pixel count… most JPGs have 8-bit depth, where HDRIs usually have 32-bit depth. In other words, you can get significantly more information into one pixel with a true HDRI than a compressed JPG. You can see the difference by lowering brightness. True HDRI whites coming from a light source stay bright as everything gets dark. Compressed whites dim at the same rate as other pixels.
