Creating a Laser

Implementing the laser tutorial

To start off with I used a small cylinder shape and gave it a white diffuse colour in the materials editor.

Using the Environment and Effects menu I added a lens effect with a glow.
I could then change the variables of the glow such as the size, intensity and the colour.
I chose to use a dark green colour for the glow as green is often the colour used in the actual film.

After playing with the settings this is the result I came up with. As this was a render effect it didn't show in the scene unless it was rendered.
