In this movie I am basically using the same smoke particles I did in the earlier movie. But this time I am assigning the smoke particles to a second emitter, a smaller emitter. So I have two emitters which is making my smoke appear thicker. You could also take these two layers in a compositor and composite them separately, however I am doing them all for the purpose of this movie in one render. I have also, as you can see, a directionalLight and a pointLight on this movie. This is without the lights on and this is with the lights on. So you can see that lights will affect particles. Let me show you my Outliner and go back to the first frame here. And in my Outliner, you can see I have the big plane, which has emitter1 on it, that surface emitter on it, and then I made a smaller emitter right there, which has emit1 on.
Now emit1 is emitting the same smoke particles at a rate of 120 particles per second and the bigger emitter is emitting them at the rate of 100 particles per second. So I have therefore two layers of smoke happening essentially in this movie. And they are moving at different rates, which is a good thing. In the Relationship Editor, the Dynamic Relationships, you'll see that I have my particle_Smoke_particles are being emitted from both emitters. Same particle, so it has the same field on both on them right there.
So if I played this, you'll see here comes my smoke up. You can see the kind of the top little layer of particles are going a bit faster up here, because they are coming from the smaller emitter in the center and there they are go. That's my smoke. Now I have done something else that I am going to show you in the next little movie, which I have tried to put some fire embers in the midst of this. I am going to show you that and I am also going to show you how to increase the velocity of the particles as well.
