I have a simple 3D scene constructed from cubes. The scene runs in a viewport. I would like to show a shadow of the scene on the background (like there is some endless wall behind the scene and the shadow drops on the wall. Any easy way of accomplishing it?

An easy way to do this is to create a shadow effect using an outline mesh.
Select the mesh and click create outline mesh in the QuickHull (top panel of the scene view). Create a SpatialMaterial and tick the transparent and use point size flags. Make a gradient in the albedo and turn on proximity fade.
No doubt there’s more in depth ways of doing it using shaders though.
Thanks for your answer. I tried it and it gives some interesting result, but I don’t think it is in the direction of what I need.
What I need, for example, is if I have a simple cube, is to show a shadow of the cube falling on a wall behind it.
One pretty straight forward way of achieving it, is simply putting some very big cube stretched as a wall behind my cube, set a direct light and turn the shadow of the direct light on.
The problem is that I have many levels and in each I will have to set the wall in a different place which is not idea. I though there is en easier and faster way of achieving the same effect without an actual wall.
