Blender Tutorial - Creating an Exploding Missiles Simulation

[@MiakuTestingGrounds]

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.

[@TushyaJha]

im not getting the smoke trails even after following the steps in video,can you please help me out?

[@modifyman6977]

Yep...Global-X...Otherwise they were hurdling in all matters of directions. Oh...so why am I back here? I don't get any impact explosions. Just an entire domain apocalyptic BOOM! ...and starting on frame 1... I've deleated the particle emitter...still Boom... I've tried modular baking...Boom! No baking...no Boom? Cycles, EEvees,bake in eevees then play in cycles... No baking, partial baking, no resume, sacrificed my 970...that didn't work so I had to get a 3080.😏 I don't use Windows, (Ubuntu) and because of that fact alone, I can install the latest Blender version and continue to not support Microsoft. Maybe it's a sign of what is going to happen...One Big BOOm... And this one started out so well until, Boom. And the Boom looks great!

[@syweb2]

@@TushyaJha Did you check the Volume cubes' Viewport Display settings? I was having a similar issue, and it turned out that instead of "solid", blender defaulted to setting it as "wire", making the simulations invisible in rendered view. Just change that setting to "solid" or "textured".

[@TaeKwonMoe]

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.

i have noticed this before... for my projects i made mistake of not having needle at frame 1 and then it got all weird and had to delete and bake all again....

[@tswan1973]

This is really cool and informative. 👍👍

[@nigellill3222]

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 👍🏼🦘

[@XirRalphReacts]

I have not started the video but I already liked it. Nice work

[@randallwhiteis]

I'm trying to follow this along on blender 4.2 and I've got no smoke from the missiles at all.

[@montumeroe9593]

Thank you for your hard work all works apart from my missile's tip pointing upwards instead of at the target so they look like they're flying sideways.

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.

[@scoopof3d]

I don't see the smoke when Im in the shading section. The Render tab doesn't have the options you are showing. Changing the colors doesn't change the smoke.

[@brandonmanus]

your pace and level of explanation is amazing thank you

[@syweb2]

15:00 The menus have changed since you made this video, where can I find Volumetrics or its current equivalent? I can't seem to locate it in the current version of Blender. Secondary question: my volumetrics (smoke, fire, etc.) are not appearing at all in the rendered view, and I can't seem to find out why or how to fix it. Is there a Blender 4.3-friendly fix you know of? EDIT: Turns out blender defualted to having its Viewport Display setting for these volumes as "wire" instead of "solid" or "textured". If you have a similar problem, just change the volume cube's Viewport Display setting to "solid" or "textured".

You have to STUDY Blender like a BRAIN SURGEON TO KNOW ALL OF THESE SETTINGS! The amount of "THIS DOES THAT" & "THIS MAKES THAT BUT ONLY IF THAT IS SAVED FIRST THEN DO THIS AFTERWARDS"' It's overwhelming for someone who doesn't spend time with blender like a DAILY FULL TIME JOB! Great amount of memory! Good job making it look easy!

If you want shooting it from a cannon set velocity normal to 100 or more and gravity to 0 and then don’t change any XYZ and rotation to normal tangent and ur rocket will shooting in the direction u point, like more like unguided rocket
