Lighting only certain objects question

Development Rendering
#1

Hi guys!

I was wondering if there was a way to have a light affect only certain objects and not others. I know that there are light map channels and that is one way to do it.

However, the issue with that is that Unreal Engine currently only allows 3 light map channels and that greatly limits what I need to do.

Is there an alternative way to have a light affect only certain objects?

Thank you in advance.

You can put a post process volume over objects to block out lights and only see them when you are in the volume, but I’m not sure if that’s going to help you. It does effectively keep the lights from overlapping though which is good in some cases.

Perhaps you could explain more precisely what you want to achieve. It is hard to give a tip with this kind of question.
