Material UE4.27

[Deux_Quoi]

Hello, I am working on VFX with Niagara and I need an effect like a laser. However, after a day of work, I realized that my emissive color isn’t working. I created a basic material and added these two nodes - a vector parameter and a multiply node (with 50 or 50000, there’s no difference). But the material isn’t shining like in the tutorial (UE4: Super Simple Lightsaber Material - YouTube) at timer (1:50). Can you please help me?

I want to add some more information: I opened another project and created the same material, and this time it worked. So, I migrated this material to my main project, but once again, it didn’t work.

Could it be related to the project settings?

Hey there @Deux_Quoi! Glow on emissive materials is generated with post processing effects, specifically bloom. Are your post processing effects on?

Thank you, in fact, the bloom was disabled.
For those who may have the same question in the future, it was actually on roject settings > engine > rendering and turn bloom “on” like the picture :
