Chaos has released V-Ray 6 for Maya. New features in the latest major version of the renderer include V-Ray Enmesh, Chaos’s system for repeating geometry across the surface of an object without instancing, and procedural clouds in V-Ray Sky.
Changes unique to the Maya edition include a new V-Ray Profiler for identifying rendering bottlenecks in scenes, and extended USD support, including support for VDB volume shaders in USD.
V-Ray Enmesh generates repeating surface geometry without instancing
The release makes Maya the second host application to get the new features from V-Ray 6, following the release of V-Ray 6 for 3ds Max earlier this year. Major new features include the VRayEnmesh modifier, which covers the surface of an object with repeating geometry, in a way analogous to tiling a texture. Unlike instancing, no extra memory is used by the repeating geometry – only the source mesh is loaded – making it possible to have "billions of polygons n a scene without any impact on the memory consumption". Suggested use cases range in scale from fences to chainmail and rattan to the micro-structure of fabrics.
Updates to VRayMtl, VRaySky, the Dome light and the VFB.
VRayMtl, the standard V-Ray material, gets a new integrated Thin Film layer for creating iridescent materials like soap bubbles and oil spills: effects previously only achievable via an OSL shader. There is also a new implementation for SSS mode, which should speed up rendering of translucent materials. In addition, energy compensation has been implemented in the GTR BRDF, which should fix a long-standing issue in which reflections appear unrealistically dark at very low glossiness values. Texture projection system VRayDecal now supports displacement maps.VRaySky, V-Ray’s physically accurate sky system, gets support for procedural clouds: a feature based on technology from real-time rendering firm Enscape, with which Chaos merged this year. Other lighting changes include the new Finite Dome mode for the V-Ray Dome Light, for fine tuning light projection onto ground surfaces via three new settings: Radius, Projection height and Ground blend settings. In addition, interactive renders can now use the Light Cache GI, making IPR and production renders identical. The V-Ray Frame Buffer (VFB) also gets a number of new features, including support for viewing spherical panoramas, and a new Proportion Guides Layer to help with scene composition.
New V-Ray Profiler identifies rendering bottlenecks.
Changes unique to the Maya edition include the V-Ray Profiler, a new tool for identifying bottlenecks in scene rendering in order to optimise material settings. It tracks the time taken to render each material in a scene, breaking the result down into categories by calculation type, including initialisation and calculating GI, reflections and refraction. In the initial release, it is limited to the Windows and Linux editions of the software, and does not support V-Ray GPU or several advanced material types, including the car paint, Fast SSS, OSL and GLSL materials. In addition, support for USD – introduced to V-Ray 5 for Maya – has been extended with support for VDB volume shaders in USD, and the option to export V-Ray materials as USD Preview Surfaces.
