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 behind the cube. Light is on, but 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 don’t have a surface behind cube but i want light visible. I would like to cast shadow by moving the cube.
If I use static mesh I will need to place surface behind the cube.
I tried use particle system like light emitter but this seems to be very ineffective.
What is best way to achieve this effect?
