How can I skew an object? I have a complex mesh that I would like to change the proportions to. Using this mesh as a simplified example, how to I make this:



Into this?



Again, the mesh I'm working with is complex, so simplifying it into a 6-sided square, shrinking one face, then subdividing it would not be a viable option.
You can do this non-destructively using a Simple Deform Modifier.


Select the desired mesh
In the modifiers tab add a Simple Deform Modifier
Set the type to Taper
Adjust Factor to increase/decrease the amount of deformation.
