Forcing randomized quads to stay coplanar? I have a lot of quads on a grid, which will get displaced by a Displace modifier with a noise texture. This is my current result:


As you can see, quads aren't deformed in a way that will make them stay coplanar.

Is there any way to solve this, either with modifiers or a script?

Thanks in advance!
As @batFINGER said, you can use dupli-face.

Create a plane and parent it to your displaced mesh (the one you shown in picture).



In the object properties of your displaced mesh, go to the duplication panel and select "Faces" (the blue button on the bottom part of the picture).

 

And.... that's all...

On the left, the "tri deformed original mesh", on the right "only planar quads"

(again, thanks to @batFINGER comment)
