I am currently making a particle system that emits clouds. I want them to fade and out at the start and end of their life cycles. I created my Niagara System, made a Scale Color node and set my Scale Alpha Curve that should reflect that. No other blueprints or niagara emitters used yet. Any help is greatly appreciated!

Edit: Youtube Link of Problem.
Can you post a video of you attempting to scale it?
Not at my computer at the moment but my particle is just visible its entire lifecycle and just immediately disappears at the end of its lifecycle. Ill post a video as soon as im back.
Can you upload a higher quality? I cannot see what you are doing.
I forgot imgur compresses these so badly. Heres a youtube link
Did you extend the FIXED BOUND?
I’m not sure how much work this would be for you, but can you try creating a REALLY BASIC system and attempt to Alpha Scale it?
If it works, then that means that there’s an issue with your materials (or you made a mistake somewhere).
If it doesn’t work, that means that your current methodology is incorrect.
I was having a similar issue, changing the alpha curve in the particle emitter wasn’t changing the opacity of the particles even though the materials and particles were set up correctly. My setup was: create a particle emitter, create particle system, then add the particle emitter node into the new particle system. The problem was that the particle emitter node in the particle system wasn’t linked up to the master particle emitter, so changing the alpha curve in the master particle emitter didn’t change it in the particle system. I fixed by simply re-adding the particle emitter into the particle system and made sure not to mess with any of the properties so that they would always link to the particle emitter master. Not sure if this is the same issue OP, but fixed it for me.
