How can I change the direction of movement?

Hey @KirilSevov! Welcome to the forums!

So this is definitely a UV problem.

You can try using X instead of Y here if you don’t want to re-UV wrap the static mesh.

Now, if you want it to go left and right AND up and down, you can add Y and X values here, as well as mess with the Utiling and Vtiling in the previous node (TexCoord(0)).
