As title says, I want to animate my turbulence but only on the offset Y

I tried "Converting" a script to only move an objects position on the Y Axis to the displacement but that didnt work

You could use the Displacement Map effect and only push pixels in Y.

I'm with Michael. If you can't do what you want with his suggestion, it would be VERY tough to do in AE.

I use this all the time for smoke and fire.
Here is the expression:
[1920, time*-150]

Your offset will move upwards like smoke or fire.

The "1920" is the X position. It can be changed to any position but it remains static so it really doesn't matter.

The "time*-150" is the rate and position your offset moves. Negative values go up (odd I know) and positive values go down. The 150 can be changed to affect the speed.

Hope this helps.

Use a fractal noise instead maybe?
