Using the default Environment Texture node setting (color space: linear) it looks really dull. If I switch the node’s color space to sRGB it’s a lot more vibrant and the sunlight takes on an acceptable strength but I suspect I’m not getting much actual “dynamic range”. Should I look for another HDRI that works better when set to Linear?
