  • Vray RT: Exposure while on Perspective View

    Hello,

    When using RT in active shade, is there a way to have the same exposure in perspective view and cameras when switching back and forth from cameras and perspective view?
    At the moment when switching to perspective view, the image is completely burnt out.

    Thanks.
    Guido.

    In "environment and effects" Set the exposure control to Vray exposure control

      Hi Alex, the viewport effect of the exposure control seems to be working backwards for me.

      Without exposure control, my render is overexposed, but the viewport is fine.
      WITH exposure control, when my render is looking good, my viewport is overexposed.

        I've been looking for a solution to this for ages - it is a real pain working with physical cameras exposed correctly for a HDRI skydome. Then you need to "get in quick" somewhere with a perspective to check some texture detail and WHAM! Totally over exposed. If I've being missing a simple check box somewhere to link the exposure I will kick myself into tomorrow....

        ...however doesn't sound like it works. Is there a solution?
        (just going to check the checkboxy thing now)

        ...IT DOES!

        New to 3.5 (I think)
        The way I got it to work is I adjusted the EV of the physical to expose the HDRI they way I wanted it. Then set the Global Environment Value EV to the same amount and hey pesto perspective cam exposes the same and physical. Brilliant! No kicking of me today into tomorrow.

          Is there any solution to this? From my point of view, this looks like you can't use exposure settings for rendering while displaying shadows in the viewport... is this correct?

            +1 for a fix -- it's annoying.

              That's the way for the PhysicalCamera (max 2016/2017). If you are working with the VRayPhysicalCamera and the V-Ray exposure control, set the exposure to be taken from the camera.

              If it was that easy, it would have already been done
