V-Ray for Maya supports several of the main asset exchanges, including static/animated meshes, V-Ray materials, subdivisions and displacement, and more will follow. V-Ray’s new Maya implementation adds a USD procedural that makes it possible to load and render USD data with V-Ray, as well as export data to USD. All V-Ray features, for example, can be encoded in the final USD stage, as well as materials, textures, render settings and others. The USD format can be extended to support any type of data involved in a pipeline. Each layer establishes scene variations and permutations and brings in specific edits or updates that affect the original.
#MAYA 2022 USD FULL#
USD shares data at near full fidelity between artists working on the same assets with different software, and allows round trips.Ĭhanges made to data in the USD format are also non-destructive because modifications are stored as layered, incremental edits on top of the original. The existing OBJ, FBX and Alembic data exchange formats are well-established and work well, but only store a limited portion of the original scene data and do not carry production rendering information. When SideFX added Solaris – look development, layout and lighting tools that support USD-based scene graphs – to Houdini, and Autodesk developed MayaUSD for the Maya 2022 release, V-Ray decided to support those new tools so that assets may be shared and combined between the two applications with consistent V-Ray rendering results. This makes non-destructive iterations and new assembly workflows possible. USD also allows a renderer to attach its data to the scene description, which means the definitions and assignments of shaders, materials, lights, cameras and environments persist within the USD file. V-Ray’s current support for USD is expected to give artists more flexibility and will continue to evolve as USD itself continues to develop. As pipelines have begun to incorporate more tools and grow more complex, the need for a universal format has become more significant.
#MAYA 2022 USD UPDATE#
Initially developed by Pixar, the USD format holds the most common types of scene data – geometry, shaders, lights, rigs, hair and so on – to make it easier to share and dynamically update assets without workarounds or compromises to accommodate different software. The USD interchange format stores and moves scene data between different applications. Chaos Group has completed the first steps of its support for Universal Scene Description (USD) in V-Ray 5 for Maya and V-Ray 5 for Houdini as a non-destructive way for artists to collaborate and assemble their scenes.
