In this tutorial to unity, he makes a river and animates it. But at 1:12
when he moves the object it moves the "waves" in that direction.
But when I try to do it just does the moves at 1:09
I am completely new to the blender I have been stuck on this for ages....
Thank you for your help or any type of advice!
