Blender Tutorial - Creating an Exploding Missiles Simulation

Показать описание

Hello everyone and in this Blender tutorial we will be creating a simulation of missiles firing up and exploding on the ground! To do this we will be using a particle system, dynamic paint and 2 different fire simulations!

Loved the tutorial! Just dropping a few things here that I struggled with and found workarounds for: 1) Use a plane as the particle emitter instead of a sphere: With the sphere emitter - my custom missiles were getting launched out at all sorts of strange angles - my guess is because the default behavior for particle orientation is relative to the normal of the surface that the particle is emitted from - so if you have a sphere with face normals going every which direction, your missile can come out at every which direction. If you use a plane as the emitter, you can additionally select the Orientation Axis in the particle system's rotation box to get the right upwards initial alignment (for me, setting it to Global X did the trick) 2) The scale of all of your objects + scene really, REALLY matters for simulation parameters. My setup size-wise is about 4-5x the size of what was shown here, and with those larger objects there were a few things I needed to tweak with the simulation: 2a) The smoke velocity on the Z axis needs to be 3-4x higher to get a satisfying mushroom cloud. 2b) The simulation speed should also be closer to 1.0 at higher object scales, so your smoke and explosion clouds aren't moving in slow-mo (though it does look sick/stylized in some contexts). 2c) When making the volumetric shader / material for the smoke, you can keep the smoke density much, much lower, which makes sense, since the volumes you're dealing with are much larger. 2d) At larger scales, you might be forced to use Cycles as the render engine (rip GPU), due to the fact that Eevee's volumetrics are based on shortcuts that break down if your camera is hundreds of meters away from ground zero where the smoke is. 3) If you're struggling with getting the weight painting part working, especially at higher / more realistic scene scales, know that the 'particle radius' needs to be SUBSTANTIALLY larger for the particle brush to create those 'splots' on the explosion emitter plane's weight painting layer. 4) You can create another thin box or plane underneath the explosion emitter and set it as a 'fluid effector' in the physics tab to get the smoke to billow out in a flat plane instead of clipping through the emitter, just a small touch that makes it look better. 5) At higher scales - 1-2 missles coming out is all you need for good 'wow' factor - higher-volume smoke sims really show off a huge, billowing smoke cloud that can get pretty visually crowded/messy with more missiles impacting the same location. You could also have some fun by adding multiple force fields scattered around, and really randomizing the initial particle velocity so you can carpet bomb an entire area with explosions.

I can't tell you how much I love doing your tutorials. I learn so much from you... 😉

Another tip, when you bake make sure you are on zero and not in the middle, if you bake the weight cache not all the missles will make a mark on the plane. Hope this helps anyone.

Damn, if only this came out a few weeks ago. I was doing a missile based simulation for a school project but couldn't get it to work properly, this would've been extremely helpful for that, but thanks for sharing for the future!

Yes, I know I moved the sphere 6 grid units and not 5. I just wasn't paying attention😕

I use Houdini instead of Blender, but this tutorial is really inspiring! Thanks so much for the helpful tutorial!

This is perfect for animating my strategical advantages in chess!

Finally I understand why I can't bake! Saving the project cures it omg! Thank you for great lesson! I love it!

I tried to do this a while ago and I couldn't get it right. I had most of the stuff but not some of the minor things that broke the sims that I did. Thank you for posting this I now know how to fully do this effect.

Not gonna lie that was the smoothest transition into a sponsor that I have ever seen 😂. Great work. Love the video. Got a new sub man.

if anyone if having trouble about their rockets being not on the right x or y axis he is using the X AXIS just to let you guys know in the beginning

What addon do u use to disintergrate the default cube... It's lovely to destroy it with animations

Hope you'll be able to create more VFX tutorials like this. Thank you!

I think it was your videos where I first learned about dynamic paint, used it for a couple of things since then. Thanks man, this is another awesome idea, so many applications for this set up

Can't believe this tutorial.
I made a observation on another creators channel about a week ago saying, since the introduction of geo nodes smoke, fire, fluid & particle tutorials seem to have disappeared. Creators seem to have the attitude of, if you can't do it with geo nodes it's not worth doing.
Thanks heaps for keeping some of the "old methods" alive & showing they're still relevant along side Gnodes.
You're a legend 👍🏼🦘
