How would I make a wave pattern onto a wall? So I want to make a wall that has a type of wave pattern, and I cannot figure out a way to do it. I read somewhere saying I could use an image as displacement but that didn't seem to work for me. 
This is the type of texture/look I want ^
If anyone can give me some pointers, that would be highly appreciated!
I did kind of manage to get a wave mesh, but whenever I tried to boolean it into the wall, even if I used the default cube, plane, etc. It just wouldn't work... It either just made the cube vanish, or it didn't actually cut into it. It just left the &quot;shape&quot; of the wave as if I used a knife into it... I'm fairly new so I'm sure there is something I'm missing or just am not aware of, but my god making this wall is turning out to be a major pain...thanks in advance for the help!
in order to make this kind of texture you can play with wave and noise textures as well, here is an example:

You can twek the settings for the texture pattern you are looking for, I hope it helps you.
