I'm setting up a timelapse shot of 24 hours and have made a vertical cross HDR texture for a domelight in COPs but it the format parameter appears to make no difference. I've rendered with it set to Auto / LatLong / Mirrored Ball / Angular and Cube Map and it renders the same every time. I downloaded one of Paul Debevec's ones just to check it wasn't something I'd done wrong and that's the same. I can see in the viewport that it's not right too, I can see all the black space.
Is there anything I need to enable other than on the light itself? I'm rendering in Karma XPU - though the same happens with CPU.
Thanks for reading
