Update: Autodesk Releases Bifrost 2.1

Bifrost 2.1 now available

Marcus Nordenstam, Senior Product Manager at Autodesk, posted about the release of Bifrost 2.1 for Maya. Exciting stuff!

With a focus on new capabilities and ease-of-use, version 2.1 of Bifrost for Maya makes it possible to build compounds using rapid point-cloud lookups, nearest-neighbor searches, and raycasting. Other highlights include an improved interface for setting datatypes on nodes, making graphs more readable, and significant improvement in file IO.

Here’s what Marcus has to say about the highlights of the Bifrost 2.1 update on the Maya blog.

Geometric Queries

We’ve added new nodes and compounds for quickly querying the closest point or location, points in a radius, and raycasting. Combined with a brand-new scope for visualizing geometric queries, these nodes open the door for a range of new compounds to easily be created, including collision deformers and attribute transfer.

Improved Graph Readability

New options make Bifrost graphs more readable and easy to navigate:

  • A new icon to identify auto-looped ports
  • Value nodes display the number they represent, rather than simply “value”
  • Toggles display all node types, rather than just node names

Bifrost 2.1 Improved Graph Readability

Improved File IO

Alembic IO nodes now support reading and writing multiple meshes with a single file, keeping UV and painted attributes intact. Bifrost strands can now be serialized as Alembic curves and Bifrost points can be serialized as Alembic points – in both cases keeping all per-point properties intact. All file path parameters now have a file-browser button, making it quicker to work with file nodes in production.

FCurve Editor

The FCurve Editor now provides pre- and post-extrapolation functions improved framing and clamping capabilities, and an array of UX enhancements that make it easier to edit your curves.

FX Updates

The aero and particle graphs have both been simplified and improved to address workflow and readability. A number of smaller features have been added including properties that flag particles that have collided with an object and meshing of density volumes. The MPM sand, snow, and fluid nodes have also been updated with new ports and shortcuts, making it easier to add custom properties.

Rendering Large Aero Sims

It’s now possible to render aero sims that exceed 4GB in size. Transfer of large Bifrost datasets to Arnold is also now more efficient. To take advantage of these updates, you need to have MtoA 4.0.3 or later.

New Pre-Built Graphs

Three brand-new graphs showcasing growing FX capabilities in Bifrost are now available in the Bifrost Browser:

  • Fast Aero
  • Missile Hit
  • Vehicle Exhaust
