  • VRayLight incl/excl List ignoring reflection/specular

    Hi,

    Situation:
    Car in a tunnel.
    Some lights are outside the tunnel, but they have an indludelist with only the car, so they shouldnt be affecting the tunnel at all)

    Problem:
    The light seems to ignore the includelist but only for reflections (EDIT: Specular is there, only reflection component missing). Diffuse light reacts as expected.

    What makes me think this is a bug?
    1) I am sure it worked prior to 3.00.08 since we didnt remember having that problem in that prior versions
    2) If I take the tunnel geometry and change "visible in reflection/refraction" from true to false, the light renders correctly again but obviously the tunnel doesnt get reflected anymore which is bad.

    Is this a known issue? If not, I may be able to provide a scene.

    Things to note:
    3ds max Design 2014 with vray 3.00.08 on windows 7 pro
    The scene developed over several vray 3.x versions starting from 3.00.03 I think?


    Edit:

    Steps to reproduce:
    1) render the scene (leave the vray render region in VFB enabled for faster render and focus on problem area)
    2) Hide all children objects of helper "Tunnel"
    3) Render again
    4) Do A/B split, notice the missing sharp reflection component, but the normally visible specular component.

    Things to note:
    Check include/exclude lists of three contained lights, all include only three relevant car objects.

    Expected behaviour: No difference in the behaviour of the three lights when the "tunnel" objects are hidden or visible.
    Observed behaviour: When tunnel objects are visible, the reflection component of the vraylights is missing, specular is there.
