    Hello,

    I've a static room with the hole for the door, I want the dynamic door to impact the realtime GI (not a probe), is it possible ? For now the door doesn't "cut" the GI.

    Note : its maybe a bug, because if I modify the sun light (color, enable/disable, etc..) it does not modify the realtime GI...

    Hey! Dynamic objects cannot influence the realtime GI - only receive it from lightprobes.

    Regarding your second issue; if you can reproduce this consistently, could you please submit a bug and paste the link here? Thanks!

    Ok, so I should disable/enable the sun light to fake the door open, but then it'll cut shadows as well, has somebody faced the similar issue / how to fake it properly ?

    For the issue I think I mess up with ambient source color and sun light color.
    Only bug I found is the Environment Lighting Source setting lost when entering playmode, I just filled a bug report ( https://fogbugz.unity3d.com/default.asp?1086922_6iqgvqddj6nfga8l ).
    Thanks!

    Regarding your bug; in HDRP Environment settings are driven via the Scene Settings game object. This allows for far more flexibility than what was offered in the built-in render pipeline. Any Environment changes made in the Lighting Settings window are not supported by HDRP.

    In order to create a new Scene Settings game object, right-click in the Hierarchy panel and select Rendering > Scene Settings. This new game object will allow you to tweak numerous environment and lighting settings. Please see the screenshot below.

    Also, it is highly recommended that you update your HDRP package to the latest version (3.0.0-preview) via the package manager (Window > Package Manager).

    Now, about your original issue. Could you please provide us with more info about what you are trying to achieve? Some visual material, such as a video or a screenshot, or a repro project would be helpful. Thanks.

    Hello,

    I'm trying to have a cube using emissive with realtime GI, but it doesn't work, here is the settings screenshot, did I miss something ? There is the strange +1 +2 property but I can't click it

    Ok I've found a bug : modifying the Emission color only works in editor mode, in play mode even switching object on/off does nothing.

    I've attached the video of it.

    Edit: even in the editor switching on/off doesn't stop the emission

    UpdateGIMaterials seems to do the trick a bit but it doesnt that good,
    is there a way to force update of realtime GI ?
    It seems its updated only if I click on different editor windows...
