How to Make a Particle Explosion Part 2/2 - Houdini Particles
Hey, guys. This is Eric, back to another Houdini tutorial. I think you’re going to like this. I'm going to show you the basics and it’s effect and I want to show you what I can do with it. Well, let me show you what I can do a little bit trick and I'm not going to go in depth but I want to show you the basics so you can do this on your own.
As you can see, I have this little movie here and I want to play it. It scatters, and then it comes right into my name like so. This is Emeek 77 or it can come out this way to explode if you play it. That’s what we got. Not too bad if you asked me and I'm going to show you how to accomplish this effect using simple geometry but you can substitute your name for the simple geometry so let’s get started.
Go back to Houdini, and let’s CTRL click our sphere and bring in our sphere. Let’s double click our sphere, I’ll get and go down to the geometry level and let’s work with our polygon mesh.
Okay, let’s go back up to object level. Now, I have our sphere. Let’s go to our generate particles and hit the source from. It’s going to ask for geometry, one of the sources of particles from. We’re going to hit our sphere and hit return. Okay, and that’s going to source our particles from within our geometry, as you can see right there.
Okay, so let’s go back up to object level here. Double click down into our sphere and we’ll have a pop net now. So let’s go to our Pop Net and let’s make our pre role 24. Now, let’s go down into our Pop Net and we’re going under a mission stop, we’re going to make it surfaces random, and then we’re going to birth, and we’re going to make the constant birth rate 500.
And now let’s go back up to object level and see what we’ve got here. We have our particle meter and we have our sphere object. So let’s double click in to our particle in meter. And now, as you can see we have this merge object here at Pop Net, just select them all, Command-C, and Command-V, and copy and paste it. So now let’s select this Pop Net going to it. Under attributes, we’re going to select under initial velocity, use inherited velocity and when you do that, you can say zip it, zip track down there.
Now, let’s go back up to our object level here. We can see we have both of our objects still. Let’s double click down to our geometry level. Now we’re going to end the node, this tab and a merge.
Now, let’s tab in the blend. Now, we’re going to connect the shape, and we’re going to connect this Pop Net into our blend shape. Now, you can see we have some options here under our blend shape, move on to blend 01 to add a blend. And when we do that, let’s display this. We give this ladder here. And when we work this ladder, you can see this is the properties we want to anime. And then, when we do that, now you can set this sphere for your 9 like I did or anything else. So, I'm going to hold the ultimate key and click blend 1. Let’s make it reverse, do it like this. Now, we’ll set up this on frame one, we’ll hit the ultimate key, and click blend 1. Now, we’re going down to frame 100 and we’ll scoop this level all the way up. Now, we’ve animated that. Now, we go from frame 1 to frame 100, that comes in.
Now, you can go back up to object level. Turn the visibility of our sphere off. And now, as you can see here, we’ll do a quick screen render. You can see we have our little meta balls there and our little spheres there, our particles and when you come down here, and do quick render, you can see they’re spread out. So that’s that!
That’s basically how you do it. That’s how you do the text that I showed you at the beginning of the video, only have substituted this sphere. You can insert anything you want and this is a pretty cool little effect. I hope you’ve learned something from this, and you can apply this to many different things. It’s wonderful. Again, let me show you what we’ve been in that with you, and what you can do with it. And there you go!
Hey guys, I shot the video, I often forgot to show you the finished result. I showed you the finished result of my name, but I haven’t show you the finished result of this sphere we’ve done, so let me, we should bring this up real quick and let me play this. I’ll bring it up here a little, and there you go. There goes the finished product. As you can see it slowly comes together into our sphere. And like with that little grid underneath it, so you can see the shadows stuff. And now, you know.
Of course, we didn’t add any textures or materials to this, which is just the basic render to show you how the effect works. Once again, I hope you learned something and we’ll see you next time.
