I had been tweaking so many settings endlessly trying to fix this and with the units explanation you solved it for me! I had no idea it used different units from Maya's settings so I assumed I wouldn't change the gravity setting unless I was trying to do a space liquid sim!
A superb tutorial, thanks very much, definitely going on to the rest. Quick question, I’m doing a simulation of sloshing liquid in a bottle, would it just be a case of increasing voxel resolution to ensure the liquid is as close to the inner walls of the bottle? Ideally I need the liquid to be within the glass wall for correct rendering, can this be done relative to the bottle shape within the bifrost settings or should I just scale up the animation when I’ve created the alembic cache? Cheers
Hey I am completely new to Maya, so sorry if this is a stupid question. I am using Maya 2025 and trying to do a liquid sim via bifrost. I spawn a sphere and then when I go to the bifrost fluids drop down at the top and click on liquid under create. I don't get any liquid to be emitted. Despite an emitter having been created. I have check everything. Nothing seems to work.
it's the 4th video in your "bifrost" playlist but as it mentions :beginners guide: it's clear that it's involving everything from A to Z but it's not the first video as in playlist arrangement... so should I go with this one first or start from the very first? Like is it gonna create any problem? bcoz firstly I only want to clear my basics
Brother what's the application you used to compare the bifrost sims.. And also must say it was quite a thoughtful and very informative tutorial....really lover it..
The software used for comparison is called RV and it comes with a license of Shotgrid from Autodesk. However, just recently at Siggraph Autodesk announced they would be open sourcing RV as part of a wider initiative for the industry. I have no idea when it be available to download, but I am planning a Siggraph video soon.
Thanks for the video, it helped me a lot. However, I still have a doubt. When you applied the bifrost liquid, the particle display tab (inside the attribute editor) is already complete. But when I went to follow your tutorial, the particle Component box on that same tab appears blank and without an option to edit. How can I make the option "particle" appear in the box? Would you be able to explain to me? Well, I couldn't find anything that talks about it. Apparently without this option selected the effect does not work.
make sure you're not displaying as voxels. when its set to voxels, the particle display is greyed out. Turn on particles in the section above to activate the display section.
Awesome. Thank you. Question: It seems that the simulation breaks up after it makes contact with your collision object. Water / liquids build up. They spread evenly around, covering the surface. These sims seem to break up into separate waves. Is there a fix for that, to make the simulation more natural?
The FLIP solver that Bifrost uses is very accurate, but there's alot of settings to change to get what you want. Sadly they never did any presets, except for the sample scenes in Mayas content browser. But properties to look at are density, viscosity, etc. The Maya docs do cover this stuff and are very comprehensive. It will take time though.
Another issue.. The liquid sim is not bouncing off of my collision plane. I goes through it. I remade the plane, got rid of my previous collide nodes, reset it to collide, all to no avail... several times. Finally, I made a sphere, and that the liquid bounces off of. Any ideas?
Do you know of a clear way to instance onto a bifrost fluid sim, for example a cube instanced on the bifrost points, so that the cube animates/follows the points for sequence?
There's a way to do it yes, but perhaps look at using Bifrost graph and not Bifrost Fluids. Also try joining the Bifrost addicts discord, lots of good resources there.
Changing the gravity and density value to compensate for inability to set Bifrost working unit feels like a workaround. Autodesk should make it easier to set working units for Bifrost. Every cm is still a meter for Bifrost right? We just forced gravity and small density value.

Thanks! Most bifrost tutorials completely gloss over caching settings and local and bifrost units and performance settings!

Thank you so much man you made my work so easy i was facing many problems while using bifrost
The best 1 hour I could've spent in Sunday. Good introductory tutorial mate!
Glad you enjoyed it
This is just the tutorial I needed for a VFX shot I'm working on with a space ship flying out of a river. Thanks!
Love your tutorials!!! They are so clear and detailed. Just what I need.
Glad you like them!
This is great. Thanks for the well-structured intro.
Glad you liked it!
Great starter tutorial!
Glad you think so!
Love this tut. Thanks ❤
Thank you so much this was incredibly helpful to me
Glad it helped!
thanks for the measurement and scale explanation
My dear Sir. This was an amazing video and I love you.
no problem
Thank you so much for this tutorial! It is very valuable for newbies like me :)
Glad it was helpful!
This is awesome man can you make more tutorials about Bifrost explosion from beginning to end
its on the list, of many videos I have to do
Great presentation, thanks.
Glad you liked it!

excellent tutorial, thanks.

Well explained. Loved it.

THANK YOU!!!!!
Will you be making any new tutorials or do you have them elsewhere?
Thanks! This was very good class!
Glad you enjoyed it!
That was great, thanks for taking the time to make such a clear guide to it!
Glad it was helpful!

Hello, anyone knows how to activate in the HUD the particle count? (In Maya 2023). Awesome tutorial btw, thanks a bunch!
Bifrost Fluids menu > Display Bifrost HUD

perhaps make sure the plane as a thickness?

My Bifrost Fluids tab is not showing up at the top, any idea how to fix this? I'm in the FX menu, but it still isn't there
check you plugins. Bifrost is a plugin, even stuff like BOSS. There should be a Bifrost section in the Maya plugin manager.
@@ZeroConditionaltutorials I got it installed, thank you!
thanks dear
Thank you too
i cant seem to see the particles though
Thank you so much!
You're welcome!
Autodesk put OG Bifrost in BF Graph please
It might come at some point. Depends if the work is worth doing against other prioroties.
Cannot find bifrost options in 2024 05:05
Ok, I'd to enable two more bifrost things in plugin manager then the menu and shelf appeared.
