Skill Level Intermediate
- [Instructor] This week on Blender Tips, Tricks, and Techniques, we're going to make a fire tornado. Now it's actually really easy to make one. First, you're going to want to take this cube and delete it. And you're going to add a plane. Type space bar, quick smoke. Smoke and fire over here on the left, and let's just scale this up. Let's gives us something to work with. Pretty big here, okay. And just play it. Now, when you start to play it you'll see how the fire and smoke are generated.
And it looks kind of nice. Okay, so let's stop that. And go up to the beginning. And I'm going to go here, and I'm going to add a force. Now to add a force, you're going to hit shift A, go down to force field, and I'm going to go to vortex. And I'm just going to play this really quick. Now, if this happens that means that you have to wait for the cache to restart. So let's just go to the end, and hey, there you go. But this vortex isn't doing anything. What gives? We'll go to the physics tab, and crank this bad boy up.
And let's just see what happens. Okay, so now we're sucking it into it. So let's move it up a little bit. And switch this to point. Ta-da, fire tornado. Now that's the coolest thing, but we can even add more forces. So let's go down here, and let's say we want to add wind. Let's go down and add wind. And let's just say the wind strength is a thousand. It's going to really push up that fire vortex, isn't that cool? Yeah, that's pretty cool.
We can go down to, say, a hundred. That way it's not super, super strong. Now how do you actually animate this fire vortex moving across and destroying towns and cities? That's actually pretty easy to do too. So we're going to take this plane, and you can already see what's happening. The moment I move it, it animates. So I'm going to come over here, take this as a whole group. I'm going to hit shift C. Shift A, I'm going to add an empty, so let's go up to empty, plane axis.
Oh, it looks like it lost the selection and everything, that's okay. So we're going to select this plane. Let's just kind of zoom in here, this stuff gets kind of tight really quickly. And, okay, let's see. Everything is selected, the field, the field, the plane. We don't need to select the smoke domain. And make sure the empty is the last thing selected, it should be a lighter orange. Control P. Keep transform. And then, let's just animate this empty.
Starting over here, and, ending right about here. And just play it. Now remember, we have to wait for the whole thing to start over, so we'll just give it a second. And now look at that. A giant, menacing fire tornado coming right at you. Pretty cool, huh? Now the best thing about Blender and forces is that you can add them on the fly, and just see what happens.
So, if I, for example, go here, and I want to add another one. Gosh, I don't know, let's just add force, and strength, and, yeah, we'll leave it on point. We'll just see what happens. And we can just play that. Looks like our fire tornado is so strong that even any outside force won't affect it. There we go, look at that. Now it looks like as soon as this fire tornado comes right at us, we're going to blow it away.
So let's just drop that down to a thousand. But this is the cool thing about Blender is that you can dynamically change forces on the fly and see how they react. Why don't you go ahead and spend the next few minutes playing around with forces, force fields, and quick smoke and fire, and see how you too can generate an awesome, menacing fire tornado.
Q: Why can't I earn a Certificate of Completion for this course?
A: We publish a new tutorial or tutorials for this course on a regular basis. We are unable to offer a Certificate of Completion because it is an ever-evolving course that is not designed to be completed. Check back often for new movies.
