Making a CG Explosion while rambling like a buffoon | DRS #2

[@IagoMotaVFX]

Hello, everyone! At about 1:01:12 there was supposed to be some background music, but, unfortunately, it gets kinda hard to keep track of multiple hours of unedited footage, so I ended up forgetting about that part. Sorry about that!

[@jayosis7132]

It's alright. At least you uploaded

[@handofdecay]

That's okay, we love you regardless.

This is by far the most realistic blender explosion ive seen so far

[@brightgarinson3099]

Bro, you uploaded! Finally! Please continue, you make my day.

[@nategreyson6014]

dude, i just found your channel.... it's incredible. You are amazing, man.

[@IagoMotaVFX]

Thank you!!

[@gytiskau1865]

Everything you do here is amaizing, aspecially the amount of patience you have :D, also this = beautiful

[@IagoMotaVFX]

Thank you!

[@3dsmileCG]

Sick! Thank you so much for your effort, man Haven't created CGI explosion for a long time, but your video lighted a spark to do it again mate :)

[@Nitram-xw9ei]

No need to apologise for the background noise. I'm watching this on my work machine as it bakes a sim. Fan background noise is now like white noise to me :) And generally, thanks for your videos, they are fricken amazing. Loving the direction towards photorealism. A colleague of mine is very skeptical about Blender's capabilities. You're helping me to convince him otherwise.

[@jeffg4686]

this is really cool technique and fantastic end result.

[@SupSupa10]

Can you send me original link of the explosion in your thumnail imge ? please !

He's BACK yes ☺🙏🏾🙏🏾🙏🏾🙏🏾🙏🏾 but for how long???? J/K EPIC video thank you very much #keepfilming

[@IagoMotaVFX]

Haha, thanks! I suppose you can expect my next video to be released a couple decades from now

[@CrossMindStudio]

Man i have been trying emitter shapes for a week now. Ima try this one. Its really hard to get good shapes in explosion and mantaflow performance is giving hard time. Thanks for great info.

[@IagoMotaVFX]

Yeah, getting good-looking and realistically moving smoke shapes in blender is very difficult. There's really no simple solution to this since blender's smoke simulator is critically flawed to begin with. More often then not, I find myself trying to push certain shapes to look realistic with the use of force fields.

[@CrossMindStudio]

@@IagoMotaVFX I was looking forward to Mantaflow. I did find some improvements like you can use forcefields and stuff but overall its still the same. But i want to give it a few more tries and see if i can make a library of emitters to use for future purpose. I just need few for times where needs are absolute basic..

[@Sophron3632]

Do you need to download an additional plug-in like this? Or just use the blender program only 🙏 (I really like this kind of work But still can't find a learning resource) // because still stuck with the language I am Cambodian.

[@IagoMotaVFX]

No need for any additional plug-ins; this was all done with default Blender.

[@artstallion6029]

Dude, you're back!! Let's go!

[@ciaranpmryan]

Another super video. I’m currently following some of your older renders. Man, a 13 hour bake and the render has been running for 3 days now and probably will take until the end of the week. It doesn’t fit on to my GPU (NVidea 1070) so it’s all CPU rendering. I think I need to upgrade my CPU 😅 Also, have you had any problems with 2.8 reading baked files?

[@IagoMotaVFX]

Thank you! Wow, I wonder what you're making there; a 13 hour bake is quite a lot. In my experience, 2.8 has read baked files the same way as 2.79. I've never really run into any significant problems with that, other than the fact that blender can't continue a simulation from where it left-off.

[@ciaranpmryan]

Iago Mota I was actually following your first tutorial with the mix smoke. I think the big difference is that I added more verts/faces to the emitter. That was also probably my biggest mistake. I will try it again copying your methods exactly when it’s done rendering as I’ve also read that you use a 660ti or something similar so I guess it must’ve been something that i changed that makes it not fit on to my 1070. I also changed to ‘Progressive Rendering’ and it’s knocked about 30 minutes off each frame. I guess it’s just all about experimentation.

[@ciaranpmryan]

I guess it was the fact that I added more verts to the emitter. Redid the whole thing again today and it’s working lovely. One point I noticed was that OpenVBD doesn’t seem to copy across the colour info for the node editor. I can now also render it on my graphics card. 😊 I’ll hit render soon and upload it to my other channel when it’s done.

[@IagoMotaVFX]

@@ciaranpmryan That's great! I actually didn't know that the emitter's vert count influences the simulation speed by much. I guess that's some useful information for future projects!

[@ciaranpmryan]

Iago Mota well, I can’t be sure that’s what it was, but that’s the only thing that I changed, so more testing of that theory will be needed.

[@connormichalec]

Nice job!!! great tutorial!!!

[@StaticPhotons]

Awesome video! A lot of useful tips in here. The renders at the end look great, any chance we could get a more detailed look at your shaders and the secondary particle systems you set up for dust and sparks?

[@crypt0sFX]

Does subframe sampling work now? Your particle emitters would prove it to be true or did you import them from 2.79?

[@IagoMotaVFX]

It works for key frame animated objects. Unfortunately, it still doesn't work with the Particle Instance modifier. Trying to emit particles from already existing particles will cause some clumping.

[@ale-pg3xb]

@@IagoMotaVFX how do you emit particles from already existing particles?

[@IagoMotaVFX]

@@ale-pg3xb You can do that through the use of the Particle Instance modifier. Using it will duplicate that object onto the particles of an emitter. After that, you just add a new particle system to it, and make sure to enable "Use Modifier Stack" in the particle settings, so that it'll actually calculate it every instance.

[@SlyNine]

Tbh, the sound seemed quite good

[@zircron45]

Yet again, fantastic video! Do you possibly think you could make a tutorial on how to create realistic cumulonimbus clouds? I’ve been trying to figure out how to for months and I can’t get it to look good! And you, if anyone, would be able to make realistic cumulonimbus clouds.

[@IagoMotaVFX]

There are a few tutorials on that already out there, but if I'm able to obtain interesting results, I might make a tutorial on that.

[@zircron45]

Iago Mota most of them are cumulus and, not all that realistic. I’ve tried figuring out the methods to create cumulus and cumulonimbus clouds, and I’ve gotten close, but nothing photorealistic. I was just looking at the video “how to make smoke sims more detailed” and near the end there are some amazingly good clouds.

[@josephstalin4788]

How to make that emmiter setup 7 dont understand. Plz help me?

[@ClearlyCero]

Hey is there a reason you use the Point Cache over OpenVDB for caching your bakes?

[@IagoMotaVFX]

On my computer, OpenVDB tends to be glitchy, especially when using different smoke colors. So, usually when I'm making a less heavy simulation, I don't use it.

[@ClearlyCero]

@@IagoMotaVFXcool makes sense :)

[@drewwellington2496]

how did you animate the single verts? they appear as one mesh ("vert emitter") so i don't understand how you managed to get them to move in different directions individually

[@IagoMotaVFX]

They're all just one object that doesn't have any edges or faces. I gave that object a scaling animation, so all the vertices expand from the origin point.

[@krisp-]

Have you ever tried more stylized effects? If not, I think that would be an interesting video.

[@IagoMotaVFX]

I guess these might qualify as somewhat stylistic: kzbin.info/www/bejne/rnW5epiFbtOZp8k I find this type of stuff pretty difficult, so I guess I should make a tutorial on that.

[@SlyNine]

Did they fix the sub frames in 2.8?

[@ArtPomelo]

I really love this channel.. Always an inspiration for my vfx effects.. Wonder what do you study? Computer science? or more in the artistic area?

[@IagoMotaVFX]

Thank you! I'm currently studying something completely unrelated to CGI (business), so I'm thinking about switching rather quickly. The place I live in, however, doesn't offer many opportunities for VFX, so it's going to be tricky.

[@ArtPomelo]

@@IagoMotaVFX Glad to hear you want to switch but you could also be the next BlenderGuru for VFX. The voice is great and the videos are too. Hope to see more quite soonish.. #Mantaflow

[@IagoMotaVFX]

@@ArtPomelo Oh I wish the ad revenue was significant enough for me to afford being a BlenderGuru! I suppose that would be possible, but it'll take some time.

You mean in the shading? There, I just increased the contrast of the density.

@@IagoMotaVFX I've bought this file just to see how smoke works it's really interesting Just wondered why you have to bake separate is that due to how much it take out of the computer? Thanks Martin

[@IagoMotaVFX]

@@Martin-ll7jc Thank you! It's better to bake them separately, because different simulations use different groups of force fields. If they were to be baked at the same time, the force fields from the smoke collection would affect the particles from the "Particles" collection, which could produce some weird results.
