Getting Starting with Effects / Use a Particle Simulator

Subtitles of the Movie

Alright as we get started with Effects, we've looked at Filters, we've looked at a Behavior, just a very simple ones, and in this module we're going to make Particles, but before we do that I want to show you two very handy items that you'll need to keep in mind when you're starting to work with Effects. One of them is this, when I have the Heads-Up Display remember the D key? Because if I go to the D key it helps me toggle between the different effects and images that I will have added to my Canvas, so I have for example, just the throw effect, or the throw behavior. If I press D again it will take me to the other behavior that I added, the Fade In and Fade Out, and notice that it's changing in my Timeline as well. D again, and now it's the Bloom filter. So, it's a very easy way to just toggle through. I can change the image, I can change this, this throw effect. Maybe if I want to change the fade in, fade out properties I could do that and then again kind of Preview my work. So, a very cool thing and it will help you certainly work with that Heads-Up Display and help you identify what you want to work with. The other thing is that if you start to add these effects that you might want to Un-add them, and the way that you do that is to open up your Project Pane like this, F5 remember, and you can select one of them. Let's say you get tired of the Throw effect, you can select it, notice that the Heads-Up Display also changes, and all I have to do is hit the Delete key, and now all I've got is the Bloom and the Fade In and Fade Out. If I don't like Fade In Fade Out I choose that, and now I've just got this on my Canvas. I've still got that Heads-Up Display. Notice it says Nothing Selected. You could probably barely see it here, but now that I select that there we go. So that will help you work with some of these effects as you add Layers to your project and you might end up with literally hundreds of layers in any given Motion project so that becomes a very handy skill and technique to have at your disposal. So here we are. We're kind of more or less back to square 1, and what I'll do instead is that I'll take this Globe, and effect Ð well, I'll put it a little bit more front and center Ð and I will click this, Make Particles. So I'm going to create a Particle Emitter out of this object. So now I've got in my Heads-Up Display this Emitter Layer to work with and I've got some parameters and again the best way to get started with these parameters is just start clicking and dragging and see what it will do. There's really going to be no harm in changing any of these parameters because then you get a feel for what will happen. So here's what will happen. If my Birth Rate is 30 I'm going to have a lot of whatever I have selected spewing off of the center object and as I get started here I'm going to do just a quick little tweak. I'm going to resize this a little bit. And also I'm going to change the Birth Rate. Now, the Birth Rate of 30 is quite high. As you can see lots of these little objects started to be created right away. I'm going to change it down to 5, and now I'm going to play through my Emitter once again. I'll set my Entry Point there on the Timeline and of course I can adjust all this stuff if I want to. I can even adjust when the Emitter effect comes in. I can move it down here if I want to. So here again is my Emitter effect. I also want you to keep in mind, or I want you to look up in the upper left-hand corner this area up here, this is going to come and go by the way. That will show you the Frames per Second that your playback is playing at, and this will depend on a lot of factors here, but right now Motion is trying as hard as it can to render this, but it can't quite do it because well, there's a lot of stuff going on. I'm rendering all these objects at a Birth Rate of 5, and I'm also trying to capture this video at the same time. So, eventually your hardware will catch up a little bit and of course it'll depend on what kind of video card you have, how much RAM you have, but I have a decent machine here, but it's certainly not the world's fastest Macintosh ever built. But eventually things will start to catch up and I'll show you another way that you can speed all this playback up on your machine a little bit faster. So, you're seeing what's happening here with this Emitter. It creates lots of objects. It creates lots of whatever you have selected. So, you can change the other parameters as you see fit. You can select this area down here and if you want to change the Emission Range to not include 360 degrees worth of pattern Emission, you can also drag this around and have very fine control over how far the particles go by clicking out on your arrows, and by just simply rotating your items around, so if you want them to go down, if you want to limit how far they go you can do that, so your Emission Range has just changed there. Also, your Life, as you change that, again, the best way to see this is to just start to tweak with some of these items that you have and make some changes. So that's how you get started with the Particle Emitter, and that's how you change one object into showers of objects. So this can be very helpful when you're making things like smoke, or flames, or sparks. Not so much with little corners of globes, but again, you get the idea.
