Is there a way to lower some parts of my plane?

Hi there,

I just added a plane to my scene and laid it onto the terrain. I want it to be some kind of concrete.
But I don’t want it to have this perfect square shape.

Is there a way to lower the borders like I can do with a terrain?

Planes are completely flat and made up of only 2 triangles, so you cannot modify the borders like you want. In order to achieve this you will need a mesh (a model). You can make those in any 3D modeling application fairly simply.

Sorry for the bad news.
