[Request] Lights and Reflections

Hey Epic devs! I got a feature request for you. Now I think this is probably a pretty complex feature request, but I feel like it is important enough to be worth it. I would love if there was a property in lights that allows me to disable the “source” from being included in reflections. This is mainly to fix the issue when fill lights show up as a distinguishable glow spot in the reflections, and I would like to be able to turn it off so that I can get rid of those.


Have you tried modifying the min roughness property on the light? It’s a bit of a hack but it renders the specular reflection of the light as if the surface were at least the specified roughness. Rather than seeing a bright, well defined point you should see a blurrier more diffuse effect.

Hi Millan,

Before I create this request, does unchecking the “Affects World” property in the light fix this? Or is it something different that you are describing?

Thank you,


No that just turns the light off. I would like to just be able to make lights not appear in reflections. Thanks!!

Thank you for clarifying. I have put in a request to allow users to toggle the light asset’s reflection. If there is any other features you would like to see in the editor, please let us know.



Hi, i have the same problem now. Is there another solution to hide the reflections of the “source” from a light? Or maybe another way to have a light like the directional light without a visible “source” of the light?

I have a black wall which is like a black mirror (just 0,0,0 as base color and 0 roughness). When i set the min. roughness of the light with higher values the wall becomes grey… so that don’t work in my case.

Some images to show what i mean:
