- In this video, we set up a Bifröst fluid simulation with a viscous liquid such as hot chocolate. If you'd like the scene file shown in the thumbnail, grab it below.

Man, You have the best tutorial in Bifrost for beginner. It helped me a lot to get started on my first liquid sim project. Thanks a lot Sir.
Angelo from Philippines
Thanks Gel. Glad it was useful. Happy simming!
you're awesome bro
amazing Simulation!!!!
Glad you enjoyed it!
it was so helpful thank you very much! keep up the good work!
Glad to hear it was helpful! Thanks!
Thank you this awesome, and very easy to follow tutorial...
Thanks Mako! I appreciate your feedback.
SnapLaunch You're welcome!
it's been 20 seconds watching and i already subbed cause i know it's gonna be awesome
Thanks a lot!
Most welcome!
great
Thanks for your feedback.
yummy , yummy , yummy . you reminded me of a piece of chocolate I put in my fridge , i'm going to eat it now
did u eat it
how it was?
Suspense is killing me.
legend says that he has yet to eat the chocolate.
Very clear and simple! How many particles did you have at the end?
Thanks for your feedback LMA. I didn't record how many particles were in the final simulation, but if you are still keen to know, check out the file in the description and let it simulate to find out.
HUGE
I was having an issue with tue continuous emission thanks a lotttft
thx ;)
Any time
awesome tutorial. I do have a question though, when I do playback with my 2700x pc with 64GB or ram, it is sooooo slow. I can basically not have a preview like you have, got any clue why?
Thanks for your feedback. Unfortunately I don't know why it would be running slower than this one - this video was original done on a quad core with 16GB of RAM, so I imagine your system should provide better performance. Perhaps do you have a small voxel size? Or is your scene really big?
Sorry to be so offtopic but does someone know of a way to get back into an Instagram account??
I was stupid lost the login password. I would love any tips you can offer me
@Nash Forrest Instablaster ;)
@Zavier Jakob Thanks so much for your reply. I got to the site through google and I'm trying it out now.
I see it takes quite some time so I will reply here later with my results.
@Zavier Jakob it did the trick and I now got access to my account again. I'm so happy:D
Thanks so much you really help me out !
Love the tutorial, thank you! I had a question, how do I limit the fluid so it ends at a certain point?
Great question! I was stumped when I first tried to turn it off too. The link below has some good answers. :) Happy simming!

Waiting for Ur new tutorial about hair simulation
short sweet awesome one do more of these simulation tutorials please
can i do this with maya 2016?
Thank you for this helpful tutorial, but my collider acts like water resist cloth , what if I want to make it wet ?
put some wet water on it...simple xdxdxdxdxd
My bifrost liquid stopped working when I translated my emitter...
how i can shoot water from hose?
I use phoenix fd for this because its simple.
I have a question guys, my sims run SOOO slowly. Is there any way to speed up replaying? I believe it's something to do with cashe I have asked on Autodesk's site and it didn't work. We are running 2016. Would be grateful for any advice..
As far as I know the playback speed of the simulations depends on the processing power of your computer as it is calculating each frame real time
Thk
Welcome
How do I cache a simulation animation?
Thanks for your question Chealsea Agno! I hope you've cached many sims since you asked the question!? :p I'll do this as an upcoming video.
@@SnapLaunch yep hahaha thanks though ;)
when I open up the file from gum road, the anmation timeline is red and won't cache. ANy Idea why?
Sounds like the timeline is selected. Try clicking in it to deactivate it. Not sure why it won't cache, but just to be sure, is the bifrost system selected when you try to cache it?
@@SnapLaunch i have the same issue. the timeline gives "bifrost evaluation error" Everything works except there is no fluid coming out of the box
doing a similar thing with a viscosity setting of 30, rendering mesh in vray, but the results are terrible as the icing falls down the object in a jittery, jiggly fashion. dear oh dear.
check out the viscosity of any liquid type "in google" pick those numbers as reality because VRAY is Very real render engine.
In the latest version.. there is no longer a viscosity setting. only "scale" which does nothing but screw things up. I cannot for the life of me get my fluid to be viscous by ANY fraction. I understand its now based on a ratio of scene size and density... but I tried everything.. NOTHING works. can you help
Viscosity is still an option for me in Maya 2018. To access it, select the 'bifrostLiquidProperties1' node in your Outliner, then, in the Attribute Editor scroll down till you see the Viscosity tab. Adjust as desired.
In maya 2016 the viscosity option seems to have been entirely removed from the interface. The only option is scale and anything larger than a 2.0 causes computing frames to hang indefinitely. Even with SP6 and Maya Extensions 2 there's no change. Also, in my version of bifrost the outliner only has one bifrost object all the objects likes props don't exist at all even trying to select them directly by name using MEL doesn't work. I guess the next thing to try is Maya 2018 for it.
Scaling like that could be an inventive hack, but will likely throw up additional issues to contend with (as it sounds like you've already experienced). I know Bifrost had a major restructuring in 2017, so 2018 is probably going to be your easiest route to solve the issue.
Yeah, it's all stable in Maya 2018. I'll try and see if I can bake down my simulation as geometry or something and reimport it back into maya 2016 for the project that I actually wanted to use it on. Thanks SnapLaunch.
Youre right... thats what I did and it worked perfect =P thank you!
Did you make any sales on this?
It's free! And yes, some generous people donated.
I don't have AI Standard in 2018 Maya.
You'll want to use aiStandardSurface in Maya 2018 for similar results. Unfortunately aiStandard isn't forward compatible as Arnold was upgraded and the shading model changed, so new material settings will need to be dialed in.
I can't do it my computer crashes :(
I keep seeing a cube of particles just drop out of my emitter for a second or so and then they just disappear? Does anyone know what I'm doing wrong?
Do you have 'Continuous emission' turned on? When you say they disappear, do they stay in place and disappear or fall down and disappear from view?
SnapLaunch hi, yes I have switched that option on. They disappear once then don't seem to come back. It's a bit odd. 😕
BTW, it just took a while for my machine to run through it. AOK.
Excellent, glad it's working now
