Maya: VDB Clouds in the Bifröst Graph Editor

[@JohnyByrne]

It's so great that you share your knowledge and experience with these workflows. As always reducing complexity so others can follow. Thank you!

[@tasticad58]

This is great, thank you sir

Hello ! it's great, thanks for the demo. I work in viewport for previs and i want to know if is possible to have a cloud more white or if possible to change the color ?

[@Uhr24]

i cannot help you, sorry. my MAYA education license is not working any more.

[@GuiZMo_levrai]

@@Uhr24 ok thanks !

[@farzinmoayed2718]

thanx

[@ulipr2411]

Amazing! thank you! How would you go about applying a material?

[@Uhr24]

try this: kzbin.info/www/bejne/nJ66pYaPgdugbbc (second half of the tutorial). another way to apply a material will be part of a tutorial later this week.

[@AntonioBosi3D]

Hi mate, great tips! Is there any vdb animated cloud sky generator?

[@Uhr24]

i actually don't know. if you can find it out, let us all know.

[@artypow1601]

HI thanks for the tutorial. How do I render it with GPU? It wont let me

[@Uhr24]

i haven't tried this out.

[@marcosantos6801]

What about velocity???

[@Uhr24]

i don‘t know.

[@kungfudalonso]

Mine for a yet unknown reason isn't rendering. It is there, and came in quickly just like yours, but after adding an arnold dome light it doesn't show up. Any ideas?

[@Uhr24]

not really, david...

[@kungfudalonso]

@@Uhr24 Worth a shot, I'll have some more swings at it, ask some friends and send it off to Autodesk

[@danlefe]

@@Uhr24 no kidding

Hi, first of all THX! One question remains - is it possible to render a vdb sequence with bifröst?

[@Uhr24]

if you have a VDB file sequence, i guess yes. haven't tried it out, though.

[@floda1984]

I'm very interested in it too, but dind't find any proper tutorial for that. There are some free vdb sequence files for free around but I can't make it work.

[@mmoboxs]

Might be a stupid question but how does one scale/reposition the clouds?

[@Uhr24]

there are several nodes which handle scaling and transforming. haven‘t tried them.

[@louismelancon79]

does not show up in viewport... kind of a fail... actually faster to load an arnold volume and plug the shader.. thanks anyway

[@LHITShappy]

Hi, I'm new to Maya, does anyone know how to render Bifrost Aero effects in Vray (I'm using Vray 5 with Maya 2022)? I can render Aero with no issues in Arnold which comes with Maya by default, but with Vray I could not see any particles & fog effects being displayed in the viewport, only objects and lighting are visible. I can make Vray sort of work with Bifrost liquid by enabling Bifrost mesh, but enabling Bifrost mesh will turn any Aero effects/particles into blobs which is pointless.

[@geosesame6162]

Nice. And how to convert them into polygons ?

[@Uhr24]

too long ago, this video, francois. you have to try it out yourself. :-(

[@larvenkarlsson440]

Renderman is the slowest renderengine in the market though...

[@Uhr24]

they all have their pros and cons.

[@unrealhabitat]

Thank you! this is amazing
