MESSAGE:
This is Part 2 of our Laser series where we are going to look at methods to create something that mimics a laser light in octane.
Last week we focused on lights and light projections and therefore got a rather realistic representation of lasers.
This week we are going to change gears and look at a more nerdy, fake method. It will probably fun and the technique can, as always, be used to do some other awesome effects e.g. anime shaders.
