Some features have been modified in V-Ray Next compared to previous versions of V-Ray. The sections below provide you with more details on what has been changed to help your transition to using the latest version.
- The VRaySkinMtl and VRaySimbiontMtl are no longer available in V-Ray Next for Maya. The VRayFastSSS2 and VRayALSurfaceMtl are recommended for producing translucent materials or subsurface scattering effects for rendering objects like skin.
- The Prepass-based and Object-based multiple scattering modes of the VRayFastSSS2 material have been removed for causing compatibility issues. The material will render in purely raytraced mode for the multiple scattering effect, including when rendering scenes saved with previous versions of V-Ray.
- VRayMDLMtl is now equipped with a custom user Additional paths list that enables rendering MDL assets outside the system paths.
- A new VRayHairNextMtl is added to V-Ray for rendering more realistic-looking hair with accurate highlights and melanin color controls.
- A new Metalness parameter is added to the VRayMtl for use with PBR workflows.
- The V-Ray Proxy now supports Alembic 1.7 and layers for efficient handling and updating of Alembic data.
- The Adaptive Dome light renders faster, cleaner and more accurate image-based environment lighting completely removing the need for light portals.
- The Photon Subdivs and Diffuse Multiplier parameters have been removed from lights. These parameters affect the Photon Map GI engine, which is no longer available.
- The Automatic exposure and Automatic white balance in V-Ray Next will adjust automatically to produce the best result while you enjoy the artistic freedom to focus on depth of field and motion blur effects.
The V-Ray Denoiser now comes with some modifications and new features:
- NVIDIA AI denoiser: The VRayDenoiser render element now comes with a denoising engine menu, which allows you to choose between the Default V-Ray Denoiser and V-Ray's integration of NVIDIA's AI-based denoising algorithm. The NVIDIA AI denoiser requires an NVIDIA GPU to work and has some advantages and drawbacks compared to the Default V-Ray Denoiser. For example, the NVIDIA AI denoiser performs the denoising faster, but is not consistent when denoising render elements. This means that there will be differences between the original RGB image and the one reconstructed from render elements that are denoised with the NVIDIA AI denoiser. It also doesn't support cross-frame denoising will likely produce flickering when used in animation.
- The V-Ray Denoiser can now denoise render elements. To use this feature, enable the "denoise" checkbox for each render element in the scene that needs to be denoised.
The Global Photon Map and Spherical Harmonics are no longer available in V-Ray Next for Maya. However, opening scenes saved with previous versions of V-Ray where those features were used will still show the UI for them and they will render as before.
The line width for the V-Ray Toon rendering effect is now always in pixel values. The width type parameter is removed. The old 'world units' width type was not working correctly in some cases. To achieve a constant value for the outline width, use the new Depth Curve.
