How do I make this lighting?

[Vibin_slugcat (Azure)]

This lighting bug happened while playtesting a monster in studio. It emits light, but goes extremely fast both entering and leaving, which may have caused this lighting to occur after it leaves the room. But I’m here to talk about how to do this intentionally.

So, though this was unintentional at first and seems to be a bug of some kind, I want to know how I can achieve this effect intentionally, as I have no idea how to replicate it. If I can’t find a way to replicate it, how would I achieve any similar effects? I’ve played with a few lighting properties and stuff like color correction, but I have little experience in this.

color correction and just like tweak stuff like contrast and saturation, making the values really high or low

Alternatively,

Turn reflection to over 10,000 (or make it negative) and use Plastic or SmoothPlastic.

Then, change your skybox to something. It may look similar.
