    Hi guys! I am new in hdrp unity. I am using unity 2019.2.0f1.

    I am trying to design the interior, and I set all lights inside, and tried to bake it.

    Some of lights were baked, but some of them were not.

    As you can see in the picture, the lights in the room were baked, but main lobby was not.
    For the lights, I used an area light with point type and rectangular type.

    Here's my lighting setting.

    Please help me, I tried to bake several times, and each took around 40 minutes :(

    Thanks!

    Given that both HDRP and GPU PLM are in a preview state in 2019.2, it is expected that you'd run into issues. If you absolutely need to use HDRP for your project, I'd recommend you download the latest 2019.3 beta ant update HDRP to the latest version (7.0.1 or later). See if that helps.

    I suspect the reason your room had baked lighting while the lobby did not, is because the room is using Point Lights using the 'Lux' units. This is quite different from the Area Light in the lobby, which is using 'Lumen' unit. Your Area Lights will need to be at a much higher lumen value to be able to affect the environment. Try a value of 500,000 lumens and see whether there's any difference.
