  • ColorCorrect Texture doesn't work as DomeLightTex

    I'm using the Vray ColorCorrect node quite often to reduce the saturation of HDRIs but it doesn't work anymore sice we switched to Vray 3.3
    I can't figure out the reason for that.

    This is my test Scene:


    I'm using a Ramp as Input for the DomeLight. (It's the same with an HDR Image file)
    The output of the Ramp is also pluged into the IllumColor of the Plane in the up left corner to controll the output of it.

    Then I put an ColorCorrect node in between like this:


    I should get the same picture without the red light but instead I get this:

    You can still see the Controll plane. (Click it to enlarge)

    I tried different settings in the ColorCorrect node but no matter what it doesn't give any outputs to the DomeLight
    It's the same then using the ColorCorrectTex or ColorCorrection Node.


    You can download my Scene here:

    I know there are countless other ways to reduce the saturation of the HDRI but I want to unterstand the problem here.

    Confirmed, it stopped working somewhere along the way. I'll update you when there's news about this. Until then, you could use the new lookdev color correct nodes (2016 ext 1 and later) or one of the other plugin color correction textures.

      If you mean the ColorCorrectTex or the ColorCorrection they both don't work and it looks like they have the same problem.

        No, I don't think that's what Alex meant. Maya 2016 Ext 1 adds new color correction nodes (Maya nodes, not V-Ray ones) and they should work fine.

            You need to load the lookDevKit plugin to get the new Maya nodes.
