Hello everyone !
I’m trying to find a way to make a pulsing particle followed by a ribbon to make a kind of very glowly thruster. The best example I have is in this video : , at 1:22. This is EXACTLY what I’m trying to achieve. I have the ribbon, I have the source, I’m just trying to make this randomly pulsing glow effect.
I guess my best bet is in materials, but I’m kind of new with it. I’m more a programmer than an artist 
Thanks !
Ill give you some puzzle pieces. In your material editor you will need a Time Node, a Sine Node, and a Constant Bias to shift the sine result from -1…+1 to 1…10, which will represent the Emissive. Report back with what you come up with. <3
Thanks for your answer. I’ll try that later and come back to you
So… I’ve tried things but nothing work as intended. All I have for now is an alpha gradient, and I still try to figure out how to make it randomly pulse 
Time should be clear, it just gives a value from 0-x. If you plug that into a sine wave, you basically say sin(x). Sin(x) gives you values from -1…1. If you have a value greater than 1 in your emissive and your bloom is activated (by default it is) you basically get your pulse. If you take that information and the missing node from my last post, everything should work.
At best, what you are explaining to me will give a regular pulse of emissive, which is not exactly what I want. I really want a random pulse, something glowing like you would see while looking at a fireplace.
DId you try copying 2 or 3 sine waves and adding them together like in the link to get your desired result? If not, go ahead and ask what you might didn’t understand, otherwise don’t forget to
