This is a volumetric lighting that i made

it is very simple,i just add a plane and

in edit mode i just duplicate it like in the 3D View

and in material

i uncheck the "backface culling" And The "Cast Buffer Shadows"

and i check the "transparency" then i change the alpha to 0.050

Note:

if You Didnt uncheck the back face culling

the volumetric light will only visible in one direction

if you didnt uncheck the cast buffer shadows

The Framerate Will Drop For Some Computer

The Alpha Must Be Around 0.010 to 0.070,

above 0.070:It Looks Ugly

Below 0.010:The Volumetric is almost invisible

You Can Changes The Diffuse Color To Chane The Volumetric Color

1,2,3 Changes The Camera
