Laser beam through fog I am modeling a laser light in Blender, but I am not sure how to get the results i wish to have. The result should look like the Picture:

Use an image as the texture for a lamp. (See Avoid distortions when creating projector effect)

and add volume scatter to the world (or create a mesh around the scene as voume scatter domain) so that the beam becomes visible.
