How to use Image Based Lighting properly?

JordanN

I never tried it before so I'm complete newb but how are you suppose to light scenes with IBL like you see in Marmoset?

I've imported a cubemap/HDR image and put it in the skylight but now I get black showing up. I also built the lighting too.

I'm not sure my reference will be of much help. But this guy's blog on UE4 experimentation seems pretty interesting. This article in particular may suit of interest.

Are you sure your texture is suitable for that? It seems to only have the upper hemisphere.

Yeah, it looks like the black is in the actual panorama image itself.

There's a checkbox to make the lower hemisphere black, it is the one partially visible in your screenshot (Lower Hem...), uncheck it and it should behave as you expect.
