Picking Cubemaps for renders?
polycounter lvl 3
I mainly use Marmoset, but I also use Octane and a few other rendering engines, so I figured I'd come here to get some advice.
When I'm trying to set up an environment for my renders, sometimes I have a hard time picking a cube map. When texturing the object, I generally set the environment to "studio 2" or just the standard "panorama" in Substance Painter. That way, I either get a fairly neutral setup, or a moderately detailed one so I can at least determine how much will be visible in my metallic/specular maps.
Once I move over to a rendering engine though, I really want to just NAIL that render, with a real nice atmosphere, proper lights and light colors, and just a good feel to the object. How do you guys go about picking your cubemap for each object that you render? I see a lot of just "black" looking ones on Artstation. It seems to be a common theme. I'm specifically thinking of Greg Rassam, though to be fair, it's definitely possible that he's just choosing a solid color background or a heavily blurred one to get that effect while still using a true cubemap.

This knowledge will then help you pick out appropriate image based lighting. Without this understanding, I think you're basically shooting in the dark, randomly picking things until you occasionally find something decent.
