    I’m trying to light a sports stadium using HDRI. My camera is situated in the bowl of the stadium. I can’t seem to get direct sunlight in my shot. The HDRI image shows a sun and seems to be bright but when I render it out, it looks like my model is in the shadows. I try to turn my sky object around but it doesn’t seem to change anything. I know it’s working because I can see the color values lighting the scene, I’m just not getting bright light. When I try to set the luminance channel to 200% etc., it doesn’t seem to do anything.

    Anyone know what I’m doing wrong? Am I expecting too much from HDRI? Is this an impossible question to answer because you don’t know what my HDRI looks like? Thanks.

    Do you have Global Illumination turned on in Render>Effects?

    I think I’ve figured out my problem; linear workflow is screwing me up in v12 but I’m starting to get a handle on it. Some of my settings (color/project etc.) weren’t set to linear. As soon as I got everything pointed in the linear direction, it started to pop.

    Also, I was using an hdri image that was 3000 pixels wide. I bought a hdri image that was 7000 pixels wide and that made a difference as well, but the linear thing is what was really holding me back.

    If anyone has any other ideas; I’d like to hear them but I think I’m on the right track now.
