Today's Maya workshops focused on particle emitters. These are nodes that are designed to spew particles that when properly modified can be potentially anything. Our first use of them was the omni-emitter which spreads particles in all directions. We also had the chance to explore the use of colour and modifying the spread for different effects.
After this tutorial, while I was compositing the dynamite and the effects I thought I'd go back and touch-up the old alley scene, cleaning up the particle fog so it looks like fog and not a sea of massive clumps of dust by using a Gaussian blur. The effect difference that came from this change adds a much more spooky yet believable feel to the scene.
