Welcome to Valhalla, your source for Bifrost-related tutorials, techniques, tricks, hacks and ideas!

I'll be posting Bifrost-related information at a variety of levels, from simple how-to's for the generalist, to in-depth, technical explanations for the advanced TD.

Bifrost FX is still relatively new, but there is a growing source of information available. If you're new to Bifrost, here are some good places to start:

Maya 2016 Documentation

Of course, the Maya 2016 documentation is the place to be if you're just starting out. This page in particular will help you get started if you've never used Bifrost before.

The Area Forum

The Dynamics forum on The Area is attended by quite a few Autodesk designers, developers and QA people, as well as people who have been using Bifrost since Maya 2015.

Igor Žanić's Work

Igor has been working on some production-level Bifrost tests and simulations, and he's on his way to building a library of Bifrost effects. His R&D is invaluable to understanding how things work at the generalist level. Two pages that are helpful are Igor's Bifrost 2016 page and Igor's channel on Vimeo.

Youtube Demos

Daryl Obert has covered Bifrost usage from a high-level demo perspective on his Youtube channel. In particular, Guided Simulations in Bifrost and Adaptive Aero Solver in Bifrost will give you a basic idea of what to expect in setting up a scene.

Bonus!

I did up a little aero demo for the inaugural video. It shows how to do emission for a simple aero explosion.

Support files are the final Maya scene and the Alembic cache of the emitter.

This is awesome. So glad you guys made a blog for Bifrost related work. I was not able to rollback my driver to 340,66 or below since I'm on a GTX 970. However if you go in your preferences/display and scroll down to viewport 2.0, you can change the rendering engine to Open GL Core Profile. That worked for me.

Amazing! Cant wait. Little wish list for aero solver: -Motion blur -Initial state -Temperature grid -support for Maya`s force field -Maya`s emitters -static grids that can be textured

mandark1011, Could you email me please to open up a line of communication so we can take a look at the issue? john.syracopoulos@autodesk.com tnx

@mandark1011: yes, you can still render the voxel data in mentalray. What you're experiencing is display-only.

Im running a NVidia GTX 970 and it doesnt seem like the drivers go back far enough to get the pre 340 series. Is this something that will be corrected soon? is it just a display issue? Can i still render the voxel data from Bifrost?

@toha: yes, that's what we're working on, but for now the best way to introduce noise into a simulation is by doing this.

Thats exactly the issue im haveing thanks ill rollback on my driver.

Nice! But Why not just inbuilt curl noise into frost? it's not always possible deform source geo

Are you seeing a white cube at the origin instead of voxels? This is a sign that your graphics driver is incompatible. This is a known issue, and has to do with some NVidia graphics cards and their drivers. Try using version 340.66 or less, see if the voxels show up.

My Maya 2016 wont process the Voxel data in bifrost. Is there a fix for this?
