So how do HDRIs emit light?
Renders look beautiful when you use them.
I downloaded Photosphere and checked it out.
Sounds very involved. A lot of work.
I guess that's why companies sell premade HDRIs.
What are the best sources for premade HDRIs.
Are a lot of you Carrara users using this lighting feature now?
Or do you just use Skylight?
