Particle effects can be used to create everything from realistic smoke and light to abstract design elements. In Maya Particle Effects, Audri Phillips demonstrates the particles she has found helpful in her work creating dynamic visuals for video games,film and fine art. This course goes deeper than the basics, tackling topics like saving time by reusing MEL expressions, implementing physics to create realistic effects, and manipulating paint effects to give particles the look and feel of an envisioned design. Exercise files accompany the course.
In this movie, we will explore the Dynamic Relationships window, which is extremely useful when working with particles. As you can see we have a particle3 in the scene, we have a particle1, we have an emitter1 and an emitter3. Let's play it a bit. See what's happening here. Now I am going to go and open Window > Relationship Editors > Dynamic Relationships. We are going to select particle3 in the Outliner. You can see that particle3, if I hit the All button, shows all the Fields, Collisions, and Emitters that particle3 could possibly be associated with.
Right now, particle3 is only associated with emitter3 as illustrated by this tan line. particle1 is associated with emitter1 as illustrated by this tan line. Now let's say I want particle1 to come out of emitter3. Select emitter3, unselect emitter1. And I want particle3 to come out of emitter1, select emitter1, unselect emitter3. Let's play this now from the beginning and the particles you will see have switched emitters they are coming out of.
Now I can also say that I want particle3 not to come out of emitter1. Let's go back to the beginning. I just have particle1 happening. Go back to the beginning and I am going to say I want particle1 also not to come out of any emitter. So I have particle3 and particle1, nothing is coming out of the emitters now. Nothing happens. We are going to get particle1 coming out of emitter1. I am going to get particle3 coming out of emitter3. We are back to where we started from. I am also going to get particle3 to come out of emitter1 and you can see I have particle3 coming out of two emitters.
And I am going to also have particle1 come out of both emitters. So we are going to have a real party here. And I will switch it back to the default start, particle1 coming out of emitter1, particle3 coming out of emitter3. So back to the beginning there. I am going to have a little bit more fun now. I am going to select particle3 -- I think I will select particle1. I like that better and I am going to put a field, a Newton field on it. Call it newt with a Magnitude of 50. I will go Apply and we will see my little icon for the Newton field right there.
And particle1, you can see now has a Newton field that's associated with. Particle3 also has the option to be associated with the Newton field but it's not highlighted, so it's not associated with the Newton field yet. I am going to click this, go back to the beginning. And look at that. Now I am going to also make particle3 associated with the Newton field. Click on that. And I have both sets of particles being affected by the Newton field. Now I am going to unselect particle3 from the Newton field and I am going to take particle3 and I am going to put another field on it. I am going to put Gravity on particle3, call it gravity, Magnitude about 60 and I will go Apply.
And look at this. So we have particle3 being influenced by Gravity right there. Now I am going to say that I want particle1 also. Click on Gravity for that one. Now they are both being influenced by Gravity. Not too influenced by newton1. Gravity is kind of stronger than this Newton field here. I am going to un-click gravity1 from particle1. It goes back to being affected by the Newton field. particle3, I am going to un- click Gravity from it. And now I am going to have it be affected once again by the Newton field. So we are back to this party here.
So you can see how the Dynamic Relationships window can be very useful to associate different particles with different emitters. You can even have the same particle being emitted from numerous emitters. And you can also turn off and on fields on different particles. And later on we will be talking about collisions as well. That's it for this movie, onwards and upwards to the next one.
