Hi,
I'm having an issue with the GGX material. The scene just has one rectangular panel light straight in front, the object is just a cylinder.
I created a metal type of material so normally you would only see one light reflection in the center of the cylinder. But if I leave the default value of the GTR tail falloff to the default number 2 (ref image : Material_02_result), then you start seeing light reflection on each sides like there is 2 extra lights on the left and right of the cylinder. When I bring the GTR tail falloff number to 3 (ref image : Material_01_result) then you get a more realistic look with only one centered light reflection.
How is this possible to get light relfection on each side? this is not realistic so I'm trying to understand how those parameters are influencing the light reflections to "create" 2 new lights.
But also if I look at the reflection map generated, it looks like fine with only the light reflection centered on both results.
