  • Reflect Glossiness Multiplier issue

    The scene is very simple: a sphere on an VRay plane illuminated by a Hemi light with an HDRI map. The sphere has a chrome material, with a bitmap applied to the Reflection Glossiness map:

    Keeping the multiplier value of the Reflect Glossiness map to 100%, the result is as expected:

    but if I change the multiplier value to 99% (or lower), the glossy reflections disappear completely from the render:

    EDIT: Reviewing the issue, I find a linear behavior of the map as follows:

    0% --> Map applied at 100%
    ...
    99% --> Map applied at 0%
    100% --> Map applied at 100%

    (Only using one bitmap, attached to the Reflection Glossiness map)

      Hi Marcoz. I checked it using the latest builds (since March 11th) of both V-Ray for Blender and V-Ray Standalone
