Flickering light - Emissive material doesn't react

Hi guys, I rebuild a flickering light based on a tutorial and everything works fine - excpect the flickering of the emissive material and I can’t find the problem here.

As I can see everything is properly set up, but it does not work.
The emissive material is in the second slot, so I do not see a problem here :confused:

I hope you can help me.
Thanks in advance and have a great day!

Please show your Material nodes.

Also make sure you do not have splitscreen if you want any bloom effects from the emissive material. It will sill light up in splitscreen but will not bloom.

Hallo,
here is the material setup - just a Constant3Vector and a Color Parameter. In the instance I change the emissive color to set the initial brightness.

What do you mean with splitscreen? Actually the blooms works in the editor with this static emissive material.

What you might want to do is have a scalar param that you set when it flickers. then multiply both the base and the emissive by that parameter. I think what is happening it that it is flickering the emmisive but the base colour is still their so it is hard to tell.

Nah, the emissive intensity is set by a Color Curve.
Okay, maybe the Base Coler lowers the effect, but even with a black base color, nothing happens.

Thank you. Can you also show how you are making it flicker?

The whole blueprint is in the link I’ve sent above BUT I have found the solution. I’ll post it at an answer.

I’ve found the solution - the blueprint is perfectly fine and everything is what it should be.
The problem war, I didn’t set the Emissive Parameter correctly. I’ve set the default value accidentially to Emissiv, but Emissive is correct. The classic one - forget one letter and nothing works :smiley:

Anyway. Thanks to of you guys and I hope someone will find this usefull.
