How to use an exr file for IBL?

Unity Engine
1

I imported an .exr file from Substance Design into Unity, converted it to a Cube Map, used that Cube Map in the Lighting Tab under Skybox, and turned the Ambient Intensity to 0. The lighting seems to work but my mesh is dark gray (attached). If I turn the ambient up I see my texture and it looks fine. I thought IBL is only needed. What am I missing?

Thanks.

Ambient intensity is a multiplier for the ambient source.
