I can't seem to get rid of the noise appearing in the vertical lines of my structure.
The material of the panel is a metal paint, they have some indirect lighting going. this light is created with a material with luminance and a bit of glow. There are no intersecting elements going these panels are 2 mm apart. I don't know where to look for the problem. Global illumination settings, material reflection settings or light source material. I can't seem to get rid of it. Does anyone have a suggestion ??
