    Datamsith: Exclude Lights from Global Illumination?

    When importing a 3dsmax file I get all the lights.
    But I can't find the option to exclude the Light effecting Global Illumination.

    When creating a Rect-Light inside Unreal, or a Spotlight, you can clearly find that option.

    Is this just not possible when importing a scene with Datasmith?

      Sorry, I tried today to get all the data under the mentioned scene root. But nope, there is no way to get the same data as if I would use an Unreal Light itself.
      Where in the DefeaultSceneRoot should I find the settings?

          I am exporting a standard Rectangular Vray Light. Datasmith is exporting the light - but I am missing important features you have when creating an Unreal light.
          One of those features is Affect Global Illumination.

          What means, I want to turn off the GI options - but I can't.

          When you export just a simple light and bring that one light into Unreal using Datasmith - you will see that problem.

          Here is a download link, that contains all files for testing:

          - 3dsmax file + vray light
          - datasmith export file
          - UE4 project file with imported datasmith file
