Particles: Adding emitters

“

- [Narrator] Emitters control the size and the shape of the area that emits the particles. The idea is to connect 3D geometry to the ParticleEmitter node, and the particles will be emanated from its polygons, vertices, and edges. We have a Nuke script to load, so we'll go to File, Open, Project Media, Lesson Six Media, 02 Emitters Nuke script. Open that and cursor in the viewer, type F to wake up the 3D viewer, and we'll Play. So, I've got a basic little setup here. We're using our snowflakes here. I'm using Frame Four cause its a little nicer shape, and the ParticleEmitter node just has a couple of little settings in it; a maximum lifetime of 20, size of 0.1, and a spread of 0.25. Now, we already talked about setting up the particles, and now we're talking about the emitters. You don't have to do it in that order. You can do the emitters first and then the particles second. So, let's take a look at how we'd set-up an emitter. A ParticleEmitter node has an emit input. You connect this…
