Signage Backlighting Question

I want to express it like a picture, but how should I do it?

HI,
you can add a thin layer below your text and give that emmissive material. will work like a charm.

In this way, however, there is no effect of spreading the light.


The light doesn’t spread like the picture. I want the light to spread.

please keep some space between wall and objects. try to increase the intensity and bloom level.

Maybe the environment in the first image is dark, you can also try to increase the “Bloom” and check it in the dark environment.
