V-Ray for Maya – Features
Intel® Embree Acceleration – for additional speed gains, V-Ray 3.0 includes an option to enable the Intel® Embree ray caster. Intel® Embree is integrated into the V-Ray core for static and motion-blurred geometry, proxy objects and instances.
Cache Geometry and Textures – scene data and textures can now be cached in between renders. This reduces scene load time and makes iterating even faster.
Dynamic Bucket Splitting automatically reduces the size of render buckets to maximize the use of multithreaded CPUs.
Progressive Image Sampler delivers instant feedback to artists and makes lighting and look development quicker and more intuitive.
V-Ray RT renders directly in the Maya viewport and supports final frame rendering and animated sequences.
• V-Ray RT CPU uses the new Progressive Image Sampler and supports a full range of production features.
• V-Ray RT GPU now supports Render Elements.
Better Shading and Rendering of Hair and Fur – Improvements to character and creature workflows include optimized Hair and Fur, improved Subsurface Scattering and a new VRaySkinMtl shader.
Render Mask to specify render regions using an object selection or image mask.
Trace Sets control which objects are visible to reflections and refractions.
Max Ray Intensity adds the ability to clamp secondary rays. This is an efficient way to remove noise generated by very bright sources while keeping dynamic range.
GI Texture Filtering – Added an option to use different texture filtering for GI samples. This can significantly reduce memory usage for GI calculations.
Distributed Rendering allows artists to use multiple computers working in parallel to render a single image.
Deep Image support including OpenEXR 2.2 format.
Isosurfaces – V-Ray 3.0 adds support for isosurfaces from volume grids using the VRayVolumeGrid node.
Metaballs – a new VRayMetaball node is added for direct ray tracing of isosurfaces from particle systems.
Probabilistic Light Sampling for optimized rendering calculations of scenes with many lights.
Volume Shaders – Rendering volumetric effects including fluids, fire, smoke and heat haze is faster than ever using the built-in Phoenix FD volume shaders inside V-Ray 3.0.
OpenVDB and Field3D Support – Industry standard volume formats including OpenVDB,Field3D, and Phoenix FD can be imported and rendered directly using the VRayVolumeGrid node.*
*OSX support for OpenVDB and Field3D is in development.
Object-based and Ray Traced SSS – For added detail and realism, V-Ray 3.0 now supports subsurface scattering with object-based and ray traced illumination.
New Skin Shader – V-Ray 3.0 includes a new VRaySkinMtl shader with multi-layered subsurface scattering and reflections.
