HDRP - Ambient light intensity?

    Hey Guys,

    I'm playing around with the new HDRP pipeline. I'm having trouble getting the result I want. In the legacy, or base, rendering pipeline, you could set the ambient(environment lighting) intensity. In the image, I have turned down the intensity of my directional light but notice how my shadows are still too harsh. I would like to turn down the shadow intensity and increase the ambient light intensity.

    ETA: I know I can increase the exposure on the HDRI sky, but that just makes the sky box look unnatural.

    How do I do this in HDRP?

    I got the result I wanted. I didn't set the Baked Sky to my HDRI sky. However, I would still like to adjust the "baked" intensity. How would one do that?

    Add an "Indirect Lighting Controller" component to your scene settings then you can adjust it further.

    That's what I needed! Thanks. I'm finding HDRP to be pretty cool so far, but it's definitely an adjustment to what we're used to.

    How did you get the skybox/skydome to work in HDRP? I've been strugglig to work it out .

    Add a "Scene Settings" gameobject to your scene (GameObject > Rendering > Scene Settings). In that, under visual environment, change Sky Type to "HDRI Sky". Add a "HDRI Sky" component to the Scene Settings game object. You can not set the HDRI Sky .exr in that new component.

    HDRP is capable of "ground truth" rendering (approx) in our tests. We compared with raytraces and realise it can achieve all visuals possible, so it's really a matter of deciphering what might be the right way to achieve it - and a heck of a lot is trial and error. So the only tips I have is:

    - it can be done!
    - how is up to you :D

    In 2019.3, using an HDRI sky, I'm finding in my scene that everything in shadow renders as gray, and things like character eyes are just black. To get the color back, I can use physically based sky instead, but the eyes will still be black, and there is still some gray (eg, my dark blues turn pale gray).

    What should I do to fix this?

    I find that it is a delicate balance between
    * Directional light
    * Sky light
    * Indirect light

    What makes it difficult is that the skylight affects the sky intensity, while also affecting the ambient light for the models - but only adds the sky color without taking the textures into account. So you can't set it too low, because the sky will be dark, and you can't set it too high because the models will be grey. If it was just possible to control those two effects separately... :confused:
