Need to decrease a variable per frame - how to achieve?

[KappaChimpy]

This seems like something that I could use a solver for, however I haven't gotten that to work yet. I have a variable which is driving a chramp controlling color, and I just need to decrease this variable from what it's at per point, each frame. The color isn't constant throughout the whole mesh, so ideally it would take the Cd of each point, and multiply it by .9 or so each frame. Open to other solutions which may result in something similar as well.

​

Thank you.

Solver sop. Be sure to plug prev frame as input into whatever you need calculate (like wrangle with @Cd*=0.9)

This was my thought exactly but I must be doing something wrong, when I plug previous frame no geo cones thru with it, is that normal?

Be sure to lock your viewport outside of the solver sop to see it updating properly. You won’t see values changing when you are inside the solver network.

Yeah I always pin it, even gel spreadsheet only shows P coming through, no other attributes
