What is the best way to create a backlight to a round vanity mirror? I’ve tried the disk light but it’s invisible within a room of sphere lights. I tried creating a ring slightly larger than the mirror and making it self illuminating, but it just looked like a solid object and not a glow of light. I saw someone say they place multiple sphere or rect lights around the mirror, but that is inefficient.
you need you use the newer Enscape versions with ray traced lighting and make emissive material 25k-50k-ish intensity depending on your lighting setup. older version can be faked with a photoshoped png with the desired glow behind the mirror.
