PBR is a monster.
I have problem, some object started to reflecht the sky.
I tried to change all setting in specular in different combinations,
it does not disappear.
@menthal, what am doing wrong.
i have specular.roughness at -1 in blender (tried 1.0 to)
i tried with different combinations whith intensity and color with no luck.
specular in materials section is set to black and intensity to 0.0
I used a other object i made to modify that to get the new one.
But all old materials are deleted after making the UV-map.
so the glass must be gone etc.
rougness check with debugtool is showing light grey.
It just looks like some settings are ignored.
A problem i hit more with some things.
I would call it hidden material properties.
ADD: ok it need to be white roughness . but blender is doing something weird.
I now have a white roughness and still shiny.
