Directional lights are so bright when reflected into a plane

    I'm using both HDRP and the built-in renderer (in two different projects) and I created the exact same scene in both. I'm randomizing the orientation and position of the directional lights above the plane.

    My problem is that in the HDRP scene, my light is bouncing off the plane creating a really unwanted white reflection, which is not the case in the built-in renderer (when using the same position and orientation)

    here's an example: https://drive.google.com/file/d/1Cr6Q0P9ovB19lRYqkzsTZRUXE4x0SXYv/view?usp=sharing

    I'm having from 1-3 directional lights, each with a lux value between [0, 1000] and exposure of 7.5.

    I thought of using unlit shader but I need the shadows to be cast.

    Thanks in advance

    I think it's because of your unrealistic lighting setup. I made three projects with HDRP and never encountered such issue. Unless I choose every strong sun light, high exposure with high bloom, and don't get those results.

    Could you please clarify more on "unrealistic lighting setup"?

    Thanks
