This is a really good reply and I thank you, but my I think I figured out what my issues stem from.
So your lights jut out from the ceiling which makes the emissive material and light, light up the ceiling by itself… Is there a way to accomplish something similar without making my lights jut out? I’m trying to make them flush with my ceiling but can’t quite figure it out, bumping it up to even ridiculous strengths(50k+) does nothing to help.
And my lights are already quite big 100x100 so I don’t want them even bigger.
I ended up using point lights instead of rectangle lights unfortunately, they don’t look as good when casted into the world but I can’t make the lights get the ceiling like I want it and be flush.
Thank you for your reply and time. Much appreciated.
