Apply same displacement to other object Sorry for this probably noob question, I'm kinda new to Blender. 

I displaced the floor using the clouds texture and I'd like to place the wooden path on top of that, without having gaps. How can I make the path follow the same displacement as the floor?
And as a bonus; Is it also possible to make the grass not go through the path?

Thank you so much in advance for your help :))

add a ground plane and add displace modifier.


add another plane above the ground plane. do not add thickness now. it may behave unexpectedly with next modifier.


add shrinkwrap modifier to the path plane and choose the ground plane as the target object.


add solidify modifier now to give some volume to the path.
