EXPLOSIONS in Realtime - VFX Blender Tutorial

Ok this is the most crazy discovery I made after a very long experimenting.
Basicly its a procedural workflow for creating explosions, which turned out to work IMPRESSIVLY GREAT!

Its now my favourite way of dealing with volumes (explosions, smokes, fireball, similar), instead of the traditional smoke simulation workflow.

The main big reaasons for choosing this workflow are:

- realtime animation playback (not possible with traditional simulations, except Embergen)

- complete control on the shape (not possible with traditional simulations)

- freedom to literally "model" the shape (not possible with traditional simulations)

- very small file size, 1.4 megabyte - a traditional simulation can take from 10 to 100 GYGABYTES!

- the result is unbelievably high detailed ( I was actually never able to get such a detail amount with smoke simulations)

All these good things dont happen instead when you try to create explosions using traditional smoke simulation with volumes.

Of course is not good for more complicated situations... but hey! is good to know we have a very light realtime option when it comes to stuff like this in Blender!

Might also make the happiness of productions when needing to send project to renderfarms :)

Some technical info:
- render times: average 40 seconds per frame, 256 samples
- my final subdivision resolution: 9
- graphic card: rtx 3080ti

I already respond to the professors that will complain for the missing camera shake or other irrelevant details: this video is intended to be a proof of concept, I intentionally didnt care about the render very much, focusing more on showing how it works

For people seeing this comment.
I subbed for... 1 year more or less?
Already had decent VFX understanding but the knowledge this guy deliver is nowhere near stuff that you can actually find in Youtube.
Explanation are always clear and on point because he also explains why he do "that" and why enabling this option or turning this variable up can affect the whole process.
Tutorial on car deformation and crash sim for example was a complete mindfuck and the result is just production ready.
I highly suggest you sub to this guy.

20:35 update: to fix the spike problem adjust the noise texture scale value in the shader

Probably the best and easiest way to get an explosion out of Blender out FAST and looking good. Amazing tutorial!

[HuseSalam_CG]

You are amazing man. You Albert Einstein in blender. You Stephan Hawking Broo😃

[captainbruhbeard]

The collision accuracy smoke sims bring doesn't matter with VFX this size anyway, so this is perfect for big or medium scale explosions. Sometimes the small channels really do have the best content! +1 sub sir

[blitzgamingstudios]

This is one of the best tutorials I have ever seen for blender! I love that you explain WHY you select each setting and tell us what it does, instead of just saying, "Do this, now do this, now do this." This way, we can use what we learned to create explosions that match what our needs are instead of making the EXACT same one you did! Bravo and thank you for this video 👏👏👏

[prahantingh]

I am completely speechless
You have done such an amazing work.
At first i thought you may be use some other applications but after watching this tutorial completely i don't have word
You have done a great work

[romantimofeev]

I'm shocked! The author you are just a genius! I'm serious! Thank you very much!👍👍👍👍👍

[ImperioAme]

This is amazing! I was expecting heavy use of geometry nodes, but your solution is genious!

[pineapple]

Bro, you have saved my design class final. I was worried i wouldn't turn it in in time due to render times, but this is much better!

[cg_pilot]

My fire and smoke textures aren't mixing for the fireball (15:20) what should I do?

[azgardus]

Absolutely immaculate majestic simulation and awesome tutorial

[MarcoAntonio-uzdc]

Raffo grazie veramente, questa è una vera svolta in tutti i termini per chi vuole creare simulazioni del genere

[LestZA]

Fantastic tutorial. Love how you explain every single step without wasting time. Good job bro.

[harcros]

bro Im doing an animation for my school project about a book called "Fallout" and I wanted to add a bomb dropping to an explosion, this was the only video I found that actually was easy to follow, and worked AMAZING!

[craigbaker]

Blender is AMAZING. It would seem that tinkering with extreme values and innovating can exploit cool potential that might never be seen under different circumstances. Namely: if the program were like Houdini and costing thousands of dollars you would approach the task with all kinds of very heavy complicated simulation elements and tricks. And maybe it would also look fantastic but this technique is truly awesome looking AND so light on resources it ends up resembling magic.

Oh my!!! I`m simply over the moon, that I found this channel!!! Thanks for this technique!

[nedeljkojevtic]

functional and creative in the same time. Rare to see. Great Job!
