Hello.
What is the best way of display light without any surface to cast light on?
I want to display light cone but I don’t want any wall behind my light emitor.
This is more understandable in pictures:

First picture: There is no wall between cube and horizontal pipe visible right behind the cube. Light has no sufrace to be cast on.
Second picture: There is wall between cube and pipe. Light cone is visible because is casted on wall.
Third picture: This is what I want. There is no wall between pipe and cube, still light cone is visible.
I want achieve result in the third picture, cast light without a surface.
What is best way to achieve this?
Update: The most important is ability to cast shadow by moving the cube.
Hi Hubacek.Jakub,
In this instance the best option would be to use a Static Mesh with a material that acts as your light cone.
Epic and other games employ this method often to get very specific lighting effects that are not possible due to limitations at the moment or either more expensive to use in real-time games.
You can see working examples of this in the form of God Rays in the Mobile Sun Temple and the Blueprint Office projects available in the Learn Tab. Those are setup to be simple static mesh with a material applied that handles the distinct look needed.
I hope this helps.

Most important is a possibility cast shadow by the cube.
I don’t want any wall behind cube but still I want visible light cone which can be interupted by some obstacle. By cube for example.
Is there any way how to achieve the this kind of light and shadow ?
Thanks for you response, but my idea was slightly different.
I would like to be able cast shadow by moving the cube.
Something like light based on particle system or something.
Is possible cast shadow and light without any wall behind the light ?
