I was working with the changing eyeware from DAZ and noticed that the lenses are actually lens-shaped, so I thought I'd apply a glass material. Unfortunately, when I do, I get these odd specks showing in the lens. The picture is of one of Ajax's glass materials, but I get that any time I put a refraction node on it. I've tried playing with the shading rate and shadow min bias, to know avail. Does anyone know what might be causing this and if there's a way to fix it?
