Hi!
I’m new in VFX, so the question will probably sounds a bit basic. I’m currently trying to change a float from 0 to 1, and I have no idea how. I tried using a randomizer, but, obviously, it only picks random value. I would like it to gradually increase and decrease through time. I really wanted to do it without using code (because I’m terrible at coding, I’m just an artist), so if anyone has any idea how to do that, I would be terribly grateful!
(here’s a screenshot to explain it a bit better, I did it for alphaclip, but I also need it for color change, and a simple float increaser or decreaser without using age through lifetime would save me!)
Isn’t there a time node? 
My problem with the time node is that it only increase once, but it doesn’t decrease :') But I have no idea how to do that 
VFX is really really new to me, that’s why I’m kinda struggling, sorry if I don’t make sense
Ahhh I just read the increase part. Not sure if VFX graph has SinTime, if so try that.
Otherwise add the time output into a sine or ping-pong node.
You can also do this via C# and set a variable. It’s the same process via all systems

Okay! Thank you very much for your indications! I did find a ‘sine wave’ which, when I change the frequency, increases and decreases the float, and now it’s working perfectly!!
Thank you so much for saving me
Nice!
I thought it would have to go into the input instead, but if it works it works
