BLENDER 3.4 ATMOSPHERIC SMOKE TUTORIAL

[@Local_CC]

This is insane. The noise that you're generating in the initial stage of smoke production is the absolute most crucial part. As soon as that's happening, and the noise is attached to the density, you can do whatever you want! It flows far better around objects than usual, has far more realistic details, even at far lower resolutions. Phenomenal work.

[@resilientpicture]

Thank you. Yes, source noise is very important and the better the source variations the better the output. 🙂

[@xanzuls]

The smoke density and render look really good. Hopefully the node based smoke sim sysmtem will fix the current issues as the mantaflow originical developers haven't updated the framework in a long time.

[@resilientpicture]

Thank you. Yes, there are some issues with vdb reimport and stuff which is a bummer but Blender is always improving, so hopefully more bug fix soon.

[@ailisnelis2383]

love this, appreciate you dabbling with blender, showing us around

[@resilientpicture]

My pleasure. Glad this is useful. :)

[@atiphasan7744]

If you want to create a tutorial, you must activate the shorcut display so that the audience is not confused by what you press.

[@resilientpicture]

Thank you, I'll do it for the next one. :)

[@coleorloff]

Amazing result. As usual. Interesting how much comes from the source vs the shader.

[@resilientpicture]

Thank you. Absolutely, In houdini the more time you spend creating source will directly impact the smoke end result. Blender is the same. :)

[@DigitalNeutrinos]

i love this, great job , 11 stars

Thank you.

You are most welcome and thank you

[@vifrapide8444]

hello, amazing tutorial ! I need to create a realistic cigarette smoke, can you tell me what are the most important parameters to achieve this effect ? thanks again

[@resilientpicture]

Thanks, Most important aspect of any smoke is the source. Now for cigarette smoke I would say high noise scale and reasonable intensity. Try using more smoke volume source than surface source. say 1 vol source and 0.5 surface source. Then its trial and error with velocity, buoyancy, temp and density. Hope this makes sense.

Thank you! Cheers!

[@funkerdoo]

this was exactly what i needed! only i'ssue i'm having is increasing the domain's samples seems to reduce how much smoke will be in the simulation? i initially render at 512 to test it and i could hardly see any smoke, but at 32 samples theres a lot of smoke.

[@resilientpicture]

No worries, is this rendering you are having issues with or the sim ?

[@funkerdoo]

@@resilientpicture problem solved! i just needed a force to motivate the smoke a bit more. thanks anyway!

[@resilientpicture]

Nice one, way to go

[@MILCHoney]

My first render come out as a black screen, correct camera chosen. followed step by step >

[@resilientpicture]

Did you enable Cycles? Does the smoke domain have material setup?

[@taffboyslim]

Could I use this to simulate a gas flow in a pipe if I used a cylinder for the domain?

[@resilientpicture]

I can't see why not. 🙂 But I don't think you can change the domain shape. It's a box. You can use a cylinder as a collider and contain the smoke within it.

[@gergerismail1574]

Woow Its so cool💯 I want to ask that why my object seems there if I render it? Otherwise I take of the object eye close but however objects seem. Could you help me? Thanks!

[@resilientpicture]

Thank you. You may need to hide in viewport as well as Disable in viewport and render. This can be done using the filter on the top right of properties window. Hope it makes sense.

[@pat4340]

Could I export this to notch so I could utilize notch texture deformers and effectors etc? What format would I export the smoke as? Alembic?

[@resilientpicture]

Not sure about notch, but export will be vdb or native blender format. Hope this helps.

[@pat4340]

@@resilientpicture yes thanks!

[@varaprasadchintalapudi]

when i add instances on point with distribution and geometry output. The cubes generated earlier are missing. What shall i do now?

[@resilientpicture]

I am not sure why they would be missing. Can you plese check the connections.

[@TheBrownGaming]

@Resilient Picture Company Hey, I followed the tutorial step by step and I'm 14 minutes in and no smoke is appearing for me at all, I tried evee and cycles and still nothing, can you help me with this please?

[@resilientpicture]

Hey, Are you at the correct frame? Also, does volume currently have a material assigned? Have you cached your smoke? If not this could be the issue. You may need to cache it before rendering. Hope this helps.

[@divyadileep3706]

After rendering i am able to see the smoke but after edporting only cube is there no smoke.why is that? I exported as .abc,.obj and .gtl

[@resilientpicture]

Smoke can only be exported as vdb or native blender file cache. not alembic or obj or gtl.

[@LiamSchnell]

Can't find any documentation on what the velocity scale really does - why is it set to 1 per default if that is way too much? If you can enlighten me an answer would be greatly appreciated :)

[@resilientpicture]

Honestly,I'm not sure why it's 1 but if you leave it at default you'll see that it's just way too much. Most of my work is based on trial and error and my knowledge from Houdini. But you are right, it shouldn't be 1 by default if it's way too much during render.

[@Leukick]

Do these take just as long as VDBs to render, or is there a time difference?

[@resilientpicture]

IMO vdb renders faster only because blender's native sims have to load noise and it takes time. I don't have numbers for you though.

[@Leukick]

@@resilientpicture Appreciate the answer! Ok because VDBs take brutally long to render so it surprises me that this would take even longer lol 😮‍💨

[@resilientpicture]

It's the loading of noise which the killer. I have explained this in my other video here kzbin.info/www/bejne/r4bYmKOMg6l1nbssi=5EE11ExYzM63blmL Check around 23:14 and 25:54

[@DarkStorm4110]

Hello, I did all the training according to the video, but the smoke does not work and does not show, can you help me?

[@resilientpicture]

Hi, no worries, I'll try my best, where exactly is it going wrong? Render or viewport?

[@justpoppinthings]

How do I increase the amount of smoke an object creates? I want it to fill the screen over time

[@resilientpicture]

You can use the surface and volume emission values in the smoke source object.

[@Syvum4308]

how to remove voxels in render?

[@resilientpicture]

You can use the heat attribute and color ramp to its alpha. I have explained it in my latest video here towards the end kzbin.info/www/bejne/boqqc4h5nNSaiKssi=c3agfAi2jdfU_3UW

[@carlosrivadulla8903]

how is this workflow compared to axiom solver?

[@resilientpicture]

Axiom solver is a beast. Super fast. Blender is improving but I guess it'll be unfair to compare to axiom.

[@carlosrivadulla8903]

@@resilientpicture I mean, speed is something ll be achieved sooner or later. I was most interested in a comparison in terms of control and flexibility. Ty for replying btw.

[@resilientpicture]

No worries, Blender sims aren't flexible,.there's only so much you can manipulate but Houdini in general is the king of dynamics and you can manipulate sims unlimited ways and times. Axiom has limited options when it comes to flexibility but future versions may include customer solver inputs. That's my understanding

[@naytbreeze]

In my smoke sim the smoke feels like it’s moving too fast. What setting controls the speed of the smoke coming from emitter again ?

[@resilientpicture]

@@naytbreeze There are a few things to control speed, the velocity within the domain settings as well as the source movement. If the source moves fast and initial vel is set to capture that then smoke will move fast. You can reduce the inherit velocity to lets say 0.1 and try. Hope this makes sense.

[@focusedstudent464]

bro what is your spec I just use 128 resolution and it took me 30 minutes then I up scale the resolution to 256 and my blender crash , but how your processor is managing to run 256 resolution in Realtime please answer my question my processor is (i5 12400f 6 core 12 threads)

[@WhiteWeaselMotion]

maybe you should use GPU instead of CPU in render settings?

[@focusedstudent464]

Bro but in blender you can't simulate anything with power of gpu I had a( rtx 3060)

[@focusedstudent464]

@@WhiteWeaselMotion I am not talking about rendering I am talking about simulation

[@resilientpicture]

Hi, My spec is Aurora R10 Ryzen 9 5950X 12 core CPU, RTX 3090 and 64GB Ram. Maybe reduce the noise level. Make it to 2 and try, it might help.

[@palpytine]

If you're doing any presenting or public speaking you need to be super cautious of verbal tics. It feels really really odd at first, and takes a load of practice, but instead of saying "erm" or "umm" (or "m'kay") just to fill the gaps try just saying nothing at all. This isn't a conversation. You don't *need* to indicate you're not finished talking. It's a presentation and small pauses will have people hanging off your words. It's perceived as you giving them a moment to think about what you just said and adds gravitas.

Videos like these can be done in 10 minutes, 30 minutes is a long time, I speak Spanish and although I understand a little bit of English, it's complicated for me and your videos don't end up reaching the public. More do, less talk.
