really spectacular tutorial, which great results! Keep em coming!!
Thank you for your kind words
Really liked this one, the result looks amazing!
Extremely useful. Thank you a lot!
You are my man! Loved this brother..Going to practice this tonight!!
Glad I could help
Absolutely loved the video, keep up the great work!!
Appreciate it
Thank you for this tutorial! Will be learning this for my school thesis film!
Glad to hear this 🙏
very useful, thank you!
Thank you for this tutorial ❤❤
Nice tutorial！
I was looking for bifrost material, but this is actually a great source!
Iam about to publish one with bifrost this Saturday so stay tuned
@@sarkamari Thanks! Do you think that all of maya prior simulations tools like Nucleus, fluid, muscle, particles, and bullet, can be replaced with bifrost for good?
Well bifrost is capable of doing all above atm so it would be the most logical move. Autodesk is currently working on optimisation for Bifrost and if that gets sorted it would be the obvious choice if you don't want to use Houdini. I have to admit Blender is not too far behind.
So it's quite intriguing what's happening in today's industry.
very clear tutorial, thanks!
Glad to hear
You're awesome!
Very helpful and well done tutorial. You have a new subscriber. Thank you!
Thank you Gabriel
wassup Roy
Thank you ..
thx！
i like it!!!
Well done bro.
Thank you Michael
Wow...
nice teaching.
Thanks and welcome
oh....i d,t know....how can i say thanks to u sirr....🌹💖💖💖💖💖💖💖💖🌹🌹🌹 awsome
amazing to hear you found this video useful
So quick question: in the FX in Maya I don't see a Pref in my shelf do I have to enable it or? I was just wondering, and I love this tutorial!!
Going to do this when I get home hahah I’m at work
Glad u enjoyed this
Great looking clouds! with a better lighting and comp probably they would look so much better. I got the idea tho. I just have one question: why did you choose to use 3d Fluid instead of bifrost? CHeers and thank you !
Good question; it really comes down to your computer spec and how well you understand bifrost aero. I have noticed lack if viewport visibility, extremely heavy scenes and unstable caching system as drawbacks fir the CURRENT version if bifrost.
@@sarkamari Got it! I actually had a lot of trouble with bifrost i'm pretty sure that is because my computer. and Its great to see another alternative! Great videos !
Excellent tutorial! You explained everything that you are doing and why you are doing it. I will be using your techniques for some clouds in a scene I am rendering. One question I have is should we typically expect Ncache to dramatically bloat our file size? Most of what I have been studying has focused on modeling techniques and less about FX.
Great to hear. With simulation and fx cache is always part of your workflow. (For efficiency and stability)
Sometimes you bake the file as alembic. In some other cases ( packages like Houdini) you write out the cache as physical files.
@@sarkamari Understood, I will read up on the documentation.
Great tutorial. A lot of settings to tweak and I wish I knew what they all do, so I can create simulations for other purposes. Second playblast took ages to calculate on Core i5 9400f, I was wondering what is your hardware configuration, if you don't mind sharing
I understand. Dealing with simulation requires a workstation usually. I have a video on my computer spec on this channel
Hi! Thank you for your tutorial it is really extremely useful! But i have the problem - fluids don't render correctly it shows to me like black space on render. I will be very grateful if you can advice me how to fix it because i didn't find any solution :(
Great tutorial, thank you so much man! Do you why my connection with the duplicated clouds breaks when I reopen the scene? or how to fix them? Thanks!
Try using duplicate special tool when you make a copy. In the option box enable input graph
Why when I repeat the UVs do I get the same circle? The others do not appear, only the size of the one that is already there is modified.
Could I take this into Nuke and create a basic slap comp? I'm currently in my 1st year studying VFX and would love to add this to my matte painting assignment, Could do with clouds like this around some mountains I've created
Ignore this comment, I just watched until the end lol I was caching when asking the question. Incredible tutorial, thank you!!
Greetings, good tutorial, can I export those clouds to cinema 4d?
Thank you. Yes you can using open vdb
14:00 That happens to me ALL THE TIME ... and it's so frustrating. I.e. when clicking a color field, the color UI pops up and when moving the mouse it disappears, having to click on it once again. Sometimes two or three clicks on the color field is required to get the damn popup UI to stay. Anyone else having this annoying glitch?
I used your settings but my clouds don't look like yours, they are shaped more like cotton balls. How do I fix this?
Mine do to, did you find a way to solve it?
Bonjour! thank you for this tutorial. i encountered a problem, when i cache my simulation and play with the slider once the cache is done, its starting the animation over like if the cache did'nt work... My base resolution is at 400, and ive been doing trying 4 or 5 times... long wait... Any clue? cause i start to think its my computer performence which is too bad. Tschuss!
having same problem did you solve it?
@@sabrinaflipse7732 hey, I needed a fix estate of the cloud so I finally got the shape I wanted but nope didn’t solve the problem or maybe, I don’t remember. I think it was because the velocity or something down there : I forgot to put it back to 0. Not sure about my answer. Good luck!
@@clemencepiriou4812 danke :)
I keyframed the heat density and fuel box's to zero, but it continued to emit :/
same here
Hey, How long did the clouds take to render, I want to render clouds like that along with my #d landscape, the VDB clouds I have slows my render down alot
My suggestion is to render out the clouds as a pass. having them with an existing scene can be lot to handle for any computer
Hi! you are a lifesaver with this tutorial. But I have a problem on the moment when clouds are showing only on the white areas of the noise. mine just blow up fully in the cube? Where have I done mistake because I did exactly as you did. i started it again and again multiple times but still the same problem. Need help pls
From what you've explained seems like the poly plane is not acting as an emitter. Make sure there is no other emitter in the scene when you start with the 3d container and also
Check via Dynamic relationship editor to make sure your the connection between the poly plan and the container is there.
Sir you didn't use any turbulence field or volume axis field for your bg and beneath clouds?
Hi Rohit.no I didn’t because of parallax
Objects further from the camera don’t move as much
@@sarkamari okk thank you so much sir
Hello. I have a question. On ua-cam.com/video/FTK1ufe5iWE/v-deo.html when I change base resolution from 130 to 250, cloud shape becomes like sliced shape, like chopped watermelon. Do you have any idea why?
Hello sir,can you please share the hdri link which you have used?
It’s available on hrdihaven.com
12:49 mistake , you told about adding value but it didnt come up
awesome tutorial but all i got was fog not clouds :( update: redid and it came out :) 3/4s done i'm super excited :) i've wanted to make clouds since my first maya class in 2018 :)
Breaking up comes from the noise. So that might help you to find the culprit
@@sarkamari thank you for the explanation :) youre a great VFX instructor! I took 2 maya classes in university and my professor wouldn't teach us vfx :(
Believe it or not that's one main reason i share these videos with everyone. Iam glad you found them useful 😊
@@sarkamari youre awesome :) tytyty
How can I export this sim to another scene?
You can export as USD or alembic. Check the plugins section and make sure use and abc are enabled
How do I keep the clouds from moving?
You need to hold a cached frame. It's in the video. :)
A text box pops up after the caching is done..... what do I click.... as I have clicked replace and blend and it prompted me to create a new cache again..... its in like an infinite loop.... and its been like 2-3 caching cycles.... it just doesnt let me get out of it and go ahead and continue with what I want to do now that I have cached the file.
Select the container and go to ncache> delete cache
Also delete the physical cache files from the cache folder in your project directory.
That should allow you to cache the sim only once
@@sarkamari thank you!
@@sarkamari Thank you I managed to get the clouds I wanted for my scene. Really great and helpful video!!!!
Amazing to hear💪🏼
after i did nCache nothing happened? what did you do to see the clouds blown out?
Would you see any movement if you delete nCache? Caching bakes the animation in physical files so no movement should come from something else. For example when u apply fields you need to make sure the container is selected
@@sarkamari i think i had the plane and container selected. maybe that messed it up? i saw movement but they were still too puffy. but i did get a good result just by rendering, but not wispy like you had. i will post a video :) bc im so HAPPY! i've wanted to do skies since my first class in 2018! thank you again! :)
@@sarkamari these are my cloud results! :) ua-cam.com/video/_jVKZZum2Mg/v-deo.html
Looks pretty good as your first attempt. 👏🏻 You can increase the base resolution just a little bit more and reduce self shadow to get a brighter cloud.
You certainly have the talent ☺️
@@sarkamari oh thanks! :) appreciate it! any good vfx schools that you know of?
Sometimes hard to remember all these values for non English speaker. Especially when you haven't used it for a long time... Thanks.
Hi, it's best is understand the workflow. Values do change based on the scene size or your scenario. That is the reason I don't have any emphasis on values in particular.
i followed the tutorial but my clouds look very layered is there a way to fix that
