Shadow from depthmap

Hi all!
Do you have any idea how to make a shadow, even simplest one using just depthmap?
There is depth_to_mesh fx, but I would like to avoid this transition, if it is possible…

Antokhio,Thank you!
This is what I was looking for!

i think u still gonna need mesh to generate shadowmap

Checked- works with kinect2 depthmaps as well as with boxes in your example!
Nice and simple. No need for emesche stuff this time. Thanks!
