  • VRay RT & VRay Adv - different results when using Color Correction Map

    Hi,

    I think the title describes the problem Im having:

    Very simple test scene -

    Teapot on plane, lit with a white Vray Dome light, GI on, BF,LC, Vray physical camera
    Plane has grey Vray material applied, the teapot a Vray material with 1 bitmap in the diffuse slot.

    When I (only) desaturate the diffuse bitmap using a Color Correction Map, I get different results (for the teapot) when rendering with Vray RT or Vray Adv.

    The VRay RT render is always much more desaturated than the VRay Adv render - with no Color Correction Map, or Color Correction Map 'reset' the rendered results are the same using either renderer.

    So, there seems to be something funny going on with the Color Correction Map?

    Anyone else having this problem?

    The reason it's an issue for me is that I'm trying to convert some much more complex production scenes over to RT but they render differently than VRay Adv (due to color correct nodes) - and I was hoping not to have to rebuild all the materials !

      Hi Tashko,

      Thanks for the quick reply - much appreciated.
      Good to know it's a bug and not something with my workflow.
      In the mean time I will work around the issue.
