Bifrost Master Class: Getting started with the Aero Solver - Part 1

In this in-depth tutorial, Bifrost Designer Konstantinos "Kosta" Stamatelos, shows you the ins and outs of making full use of the Bifrost Aero solver.
The intent of these master classes is just to give you a good foundation for what all the "knobs and dials" do, rather than to zero in on any specific workflow or effect. This way, when you're experimenting with Aero (or MPM, or Combustion, www.youtube.co..., you have some idea of how to roughly point those experiments in the direction you want to go.

A Fracturing tool is really appreciated and works with aero would be a game changer for maya

At minute 13:26, he hid the gold! Normal for Maya's guys...

[@npmmalayalamvfxtutorials1717]

OMG This is amazing Nodes are arranged well Easy to understand And new solvers are just stunning After some years Love u guys A Lot love for the team who worked behind this project and making maya in better place Hope you guys will never give up Thanks a lot

[@keithyakouboff8755]

This does seem superior in every way to Maya's fluids. Why keep the fluid system in there?

[@DonBurroni]

More of this guy please 🙏

[@losimple]

Hey guys very very good job. Congratulations !!! And please, don not forget any fracture system update.

[@leecaste]

Nice to see this Maya update is something exciting not like previous updates that have been one disappointment after another for years. These nodes look cool, even the doted background! The regular node editor should be updated to look like this one and get rid of redundant editors (hypergraph connections/hierarchy, hypershade, shaderfx editor, etc.) And the parameters panel is very clear, the attribute editor should look like this one. Good job guys 👍

[@Autodesk_Maya]

This is what our engineers have been so hard at work on, so we're glad you like it! And this is just the beginning...

[@create3dcharacters457]

looking great guys!

[@draabuu]

Hello Maya, finally a good update for vfx artists. Unfortunately, way too late. Come on, ICE was introduced into Softimage like 10-11 years ago. I had been a loyal Maya user for a long time, but no major updates in Maya's VFX tools made me switch to Houdini and I'm not coming back. P.S. these general examples you show in promo video look like crap.

[@ChaosWolfNinja]

I do agree. Its quite late in the game but lets see what comes out of it.

[@nick_kol_nick]

ummmm nparticles maya fluids bifrost it's just up to date engine for sims also graf use JIT compilation, which is only in maya

[@BrandonRultidge]

Really good video, I learned a lot thank you!!!!!

[@Peki_THC27]

this masterclass came from heaven because i just started to get my feet wet with bifrost

[@zipporahdelong324]

This tutorial is easy to follow and I am using exactly same settings/nodes as you, but am not seeing any smoke.

[@Autodesk_Maya]

If you right-click the Time Slider and check your Playback Speed, is it set to "Play every frame, free"?

[@atlantakiriacoulis5537]

@@Autodesk_Maya damn literally have been trying to see smth for hours hahah, thanks

[@saebr]

First of all, thank you for this master class, and if course the effort put in on the Bifrost. This class cleared a lot of things for me... I lately started adding houndi to my arsenal, but it seems like Maya is doing great on this now.. With a simple to understand system. Question... Is the new Bifrost now considered as a replacement for maya fluids?? And as an earlier comment suggested, a voronoi fracture system will really be great.. And maybe while you guys are at killing it... Buy pulldownit :) Hoping to hear back from you regarding my question if this kinda replaces fluids. Thx...

[@Autodesk_Maya]

Episode 1 is focused more on aero and particles than fluids, but we are working to have a fluid solution in the future integrated into the graph. That being said, we have found that you can actually set up MPM particles to behave like a fluid already! I will try to make a video on that as well.

[@saebr]

@@Autodesk_Maya Thanks for the reply, but just to clarify ( I think I haven't used the right words for my question).. By fluids I didn't mean liquids.. I meant the the 3d fluid container and using it to create smoke oe explosions & fire. This is what I meant... Cuz it seems the Bifrost is replacing that.. Am I right?

[@Autodesk_Maya]

Ram S Ah! Yes that’s the idea. 👍🏽

[@keithyakouboff8755]

Hello... while I'm working with the tutorial I'm messing with some of the settings to see the results. I wanted the smoke to fall downwards, and so I changed the inherit velocity value, the directional speed, the buoyancy value, etc., and my smoke looks thoroughly unchanged with each value change.

[@ciecle1000]

thanks god for this channnel

[@dwilliampaul5836]

No explannation of what key command to pull up he tap seach. and search for aero. How does that menu appear?

[@Autodesk_Maya]

It's the Tab button

[@darkage1603]

Hi Can you make a tutorial about creating advance wet map using bifrost as we do it in Houdini?

[@charlesxstorm]

I don't know what's wrong, but the smoke plume is not rendering in arnold. It only renders when i switch to hardware rendering.

[@Autodesk_Maya]

Did you apply an "Assign Material" node as shown here? kzbin.info/www/bejne/apunloWMd7mjfck

[@MOHITSHARMA-pw1fy]

I missed the part where he explained what to do for high velocity objects, can anyone explain or provide timestamps?

[@leanlowkey4700]

is there a way to maximize the height of the smoke or fire? I dont want my fire to go as high as it is. is there a way to constrain the flame to make it only go so high?

[@DonBurroni]

Reduce the temperature

[@leanlowkey4700]

I cant see anything that is happening unless I do playblast is this correct or is there a way to just see what it looks like as I tweak it without playblast

[@Autodesk_Maya]

Hmm, do you mean the Viewport is literally empty when you play without playblast? Did you make sure the scene Playback Speed is set to "Every Frame, Free"?

[@leanlowkey4700]

Maya Learning Channel yes it will just show the sphere or whatever the object is. But no smoke, fire, etc. I did not check the ply back speed. I will do so and get back to you. Thanks !

[@leanlowkey4700]

Maya Learning Channel that worked. Thank you very much. Loved the tutorial and for your quick reply and help. !

How to render it on Arnold Gpu

[@alfsim7799]

Nothing to show how to render the effects in thumbnail pictures ?

[@LooMama]

Sir, thanks for sharing. I has a question. When i render with hardware 2.0, the alpha seem wrong, it become box but not smoke alpha . May i know how to solve it?Thanks Sir

[@Autodesk_Maya]

Unfortunately Hardware renderer is quite limited. You'll want to use Arnold when rendering Bifrost effects.

[@LooMama]

@@Autodesk_Maya I see.may I know can we use vray to render bifrost? If yes, do you know where do find the tutorial?

[@LooMama]

@@Autodesk_Maya sir, I try render with Arnold also. But it failed to render the smoke.not sure how to fix this. Does any tutorials to follow?

[@mms0537]

Dude I do not get smoke rather a green transparent square.I am using maya 2020.same connections given by you are given by me so is the problem with me or maya

[@Autodesk_Maya]

Try turning of ambient occlusion in the Viewport. There’s a known bug with aero and ssao at the moment.

[@S-I-T]

I have a question. Is there a way of generating vector motion maps for use in game engines?

[@Autodesk_Maya]

While I haven't tried this myself, there's no reason why not. Bifrost contains all the math nodes required to achieve this.

[@alencg2518]

Hi how to speed up calculation time ? what i need better cpu or GPU ? or both?

[@Autodesk_Maya]

Alen CG CPU is the best option here

[@keithyakouboff8755]

I have the Bifrost plug-in installed, but under Windows, there is no Bifrost Browser, and if I make a simple BiFrost container(?) from scratch, there is no option for a BiFrost graphical editor. I'm using Maya 2019.

[@IanHooperUX]

The new Bifrost extension was included with 2019.2, but if you have an older version you will have to download the plugin separately. Grab it from here: area.autodesk.com/bifrost/

[@keithyakouboff8755]

@@IanHooperUX Thanks much.

[@sanjios]

Again what is missing is intuitive interface and where are the liquids ? I'm using maya for years, didn't touch bifrost after I realized that MASH is dead. This needs to be soooooooooo much simpler and easier to use.

[@chrisgabathuler]

Is it possible to convert the simulated volume into a mesh?

[@Autodesk_Maya]

Yup. There's a few different methods actually, one of which is explained in good detail here: forums.autodesk.com/t5/bifrost-forum/how-can-i-convert-the-particles-or-volumes-to-a-mesh-using-the/m-p/8942264

[@rajdarshanr6335]

Waiting for next tuts

[@rajdarshanr6335]

Is it possible to visualize velocity?

[@Autodesk_Maya]

You can use either a "volume_scope" or "point_scope" (depending on the type of simulation) node to do that.

[@awesomeboss2020]

No Fire...? ☹ I thought I'd be seeing a fire demo, not a smoke demo. Thumbnail fooled me...

[@MrKalakhia]

Does new Bifrost supports VRay ?

[@Autodesk_Maya]

For VRay, you'll need to export the sim to a OpenVDB using either a write or file_cache node. Then you can render the cache in any renderer that support that format.

why is my smoke not rising? :/

[@Autodesk_Maya]

Have you applied any influences that might be pushing it down? Or maybe altered the gravity settings in the Settings node?

[@StylishVJ]

@@Autodesk_Maya it was a simple solution, stupid me had forgot to set the playback speed to play every frame! Thanks nevertheless for your answer, really looking forward to see what the future of Bifrost have to offer :)

[@cihankenar1]

Autodesk with 3DS Max and Maya you will have to keep innovating to keep in the game or will be overtaken by the likes of Blender, or Houdini.

yes just like C4D is more popular now
