How to achieve anime-like smears in blender? So I'm trying to do an anime-styled animation. I want to do something like a smear over the character when they move really quickly. Something like this:



Is there any way to achieve something like this in blender?

Edit: I've just tried something that kinda gets the effect I'm looking for. I took a plane and gave it a glass bsdf and then a noise texture, connected that up to a mapping node, and then altered the scale to give it this stretched look. I then put the glass in front of the model. Having the plane would help me animate this effect. The problem is that it affects the background as well. I'm wondering if there is a way to isolate this effect to just the model.
In node editor:
You could try using the displace node which moves each pixel according to an input rgb, where red is how much the pixels will move in the x direction, and green is how much pixels will move in the y direction.



(I didn't change any settings for the cloud texture, I just use the default values)

Edit: 

In 3d editor:
If you want to do it directly on a 3d model in the 3d view, you can use the displace modifier.


create a cloud texture and make the size very small.
Then add the first sub-surf modifier if your model don't have enough geometry.
Then add the displace modifier under, and change the direction to only 1 direction (X, Y or Z)
Then add 1 more sub-surf modifier to smooth things out.
