Now, whenever I'm trying to recreate natural phenomenon such as smoke or water…particles, I prefer to use stock footage of the real thing. It's going to look…more natural and more organic, more realistic. However, Apple's Motion does…come with a pretty good Particle Generator in it with some pretty passable…smoke. So, let's take a look at how you might use that instead of stock…footage to create these natural fills for light rays and other effects.…We are back in Motion. I'm going to turn off the groups that I was working with …so that I can see what I'm doing with my Smoke layer. I'm going to open…up the Library in Motion. I'm going to select Particle Emitters and they have a…category called Smoke. As you click on the different ones down here in the Name section, …you will them previewed up here in the window. I'll try Black Smoke,…Rising Smoke. I think this Basic Smoke is a good starting point, so let's go…ahead and grab that one and drag Basic Smoke into my Layers panel and it will…
Volumetric lighting effects, such as light rays and glows, are susceptible to two common problems: They can look too synthetic, and they are prone to banding when compressed for DVDs and the web. In Motion: Natural Light Effects, Chris Meyer shows how to make light look more realistic by adding dust or swirling smoke, creating natural imperfections that help with compression. He demonstrates how to do this using stock footage of this natural phenomenon or Motion's Particle Emitters.
