The DAG or object hierarchy refers to the parent-child relationships of all nodes that make up an object, serving as a breakdown of how an instance of an object is constructed from a piece of geometry.

Graph shape in the outliner Bifrost Graph Shape Nodesīifrost graphs can now be represented as either DG nodes or DAG nodes called bifrostGraphShapes, that are visible in the outliner. One strands object is composed of multiple curves, so multiple curves may be dragged in to produce one strands object. You can also build compounds that accept Maya curves acting as guide-hairs and use Bifrost to generate interpolated hairs for Alembic caching or direct rendering.īifrost strands may be resampled as part of the import process, by length or by number of segments. This makes it possible to use Maya curves to guide procedural generation of roads and fences, and to place and orient object scattering. Maya curves can now be dragged and dropped directly into Bifrost graphs, where they are converted into Bifrost strands and can be used to build curve-based assets and tools. The release also integrates the most recent version 6.1 of the Arnold renderer, and updates to the Motion Library and Substance plugins.

Its new scattering, instancing, volumetrics and FX capabilities extend proceduralism in Maya beyond FX to other parts of the content creation pipeline. Autodesk Maya 2020.4 includes a major update to the Bifrost visual programming environment that is more deeply integrated with Maya and has a new user experience.
