Enscape Compatibility

• Enscape compatibility. Scenes set up using Enscape will now render in V-Ray. Materials and even the Enscape assets will be automatically handled by V-Ray providing a great starting point when transitioning from the Enscape design stage to the high-end visualization in V-Ray
• A global Enscape Compatibility toggle is implemented. It disables the special handling for Enscape materials and assets
• * Note that Enscape assets provided by 3D PEOPLE are currently not supported

Rendering

• Resumable Rendering implemented. Incomplete renders can now be resumed where they left off from the previous session. Ensure that an output image path is specified to take advantage of the feature
• The interactive rendering workflow is updated. The Interactive UI toggle is removed and the production render settings remain visible at all times. Interactive rendering is enabled by using the Render Interactive button on the toolbar, the one in the asset editor or in the VFB
• Interactive Parameters rollout added to the Advanced Settings/Render Parameters section. A few parameters specific to interactive rendering can be changed there. One example is the Interactivity slider, another the toggle for Interactive Light Cache
• Interactive Light cache implemented. Toggle the 'Advanced Settings/Interactive Parameters/Allow Interactive LC' option and ensure that Light Cache is selected as a secondary GI engine to use it. When enabled the Automatic Exposure, Automatic White Balance and Adaptive Lights features will work in interactive sessions
• All rendering-related icons on the toolbar and in the Asset Editor are updated

Unified Login

• Chaos Unified Login implemented. This is a system that ensures a single Chaos login enables all Chaos products, services and product features that require authentication

Cloud Collaboration

• Chaos Cloud Collaboration implemented. This is an image-sharing platform available for free for all V-Ray users. Use the shortcuts in the VFB for a quick image upload. Note that the platform is still in beta

Cosmos

• Cosmos is updated to its latest version
• Cosmos is the new central and only remote assets provider. The legacy remote contents downloader is deprecated and is no longer part of V-Ray
• Material Library in Cosmos. The built-in V-Ray material library is no longer available in the Asset Editor. Use Cosmos to browse and import preset materials in your project. Note that the vrmat library panel will remain as part of the Asset Editor mainly for managing custom asset libraries
• A shortcut that opens the V-Ray Material Library in Cosmos is now available in the left fly off pane of the Asset Editor. Select the default Materials entry to see it in the contents pane
• The logic used for importing Cosmos materials is improved in numerous ways to accommodate the new library workflow
• Light Gen environments from Cosmos. Light Gen no longer uses a proprietary system for downloading its HDR environments and instead gets the images from Cosmos. Note that saving and loading .lightset files is temporarily disabled
• Cosmos materials are now automatically selected after import

Procedural Clouds

• Procedural clouds can now be enabled in the V-Ray Sky. Select the Sun Light in the project to change the clouds parameters
• Dynamic Clouds implemented. Enable the option in the sunlight parameters and the clouds will automatically move when the time of day changes. Use the Wind Speed, Direction as well as the Phase Velocity parameters to control the movement

Enmesh

• V-Ray Enmesh Implemented. Apply the Enmesh modifier to an object and then pick an item to cover the object’s surface forming a 3D pattern. Note that the base object's UV texture coordinates determine the items positioning
• Enmesh crop-box preview implemented. Changing the Spacing parameters in the Asset Editor reflects in the viewport preview showing the way the pattern-forming objects are spaced or cropped

Asset Tagging

• A new Tags system used for grouping the scene assets in the Asset Editor is implemented. Use the tags to organize and work more efficiently in complex projects
• Tag entry added to the assets context menu in the Outliner. Use it to create new tags, change the asset’s tag assignment or add multiple assets to a tag all at once
• Tag assignment via a drag and drop of an asset is implemented. Note that only a single asset can be added to a tag this way

Camera Clipping

• Camera Clipping options added to the Advanced Camera Parameters rollout. Use the feature to clip nearby objects in tight spaces

Material and Texture Improvements

• Distance Texture implemented. The texture outputs color values based on object proximity and can be utilized for restricting Fur generation or even be used as a displacement map
• Dirt texture Exclude and Affected By options implemented. Exclude objects from the dirt effect or make sure they are ignored when calculating the proximity
• GTR energy compensation is enabled for all V-Ray Materials. The option ensures more accurate reflection values for most blurry reflective materials using the Microfacet GTR (GGX) BRDF model
• Thin Film parameters added to the V-Ray Material. Toggle the advanced parameters to see the Thin Film rollout
• Car Paint 2 material implemented. It replaces the legacy Car Paint in the UI and comes with an improved flakes and coating layers
• The rendered appearance as well as the UI of V-Ray Materials using the SSS Translucency are improved
• The Bitmap texture’s parameter previously known as Color Space is now correctly renamed to Transfer Function. It determines the gamma correction curve applied to the bitmap
• Automatic Transfer Function mode added to the Bitmap texture. It automatically determines the color transfer function. If a bitmap file name contains the suffix ‘_srgb’ the transfer function is sRGB. If a bitmap file name contains the suffixes‘_lin_srgb’ or ‘raw’, no correction is applied. For bitmap files with 8 bits per color component and 3 or 4 color components (like png, jpg and other), the transfer function is set to sRGB. In all other cases, no correction is applied
• Mix Amount parameter is added to the Mix (Operator) texture. It specifies the degree to which the two input textures are blended
• The slider precision for the Reflection Glossiness ,Metalness and refraction Glossiness parameters of the VRay Mtl is increased
• Local Space Bump mode is added to all materials that support bump mapping. Enable it to measure bump amount in local texture space instead of in world units. This mode was previously called Bump Texture Channel and should be selected when an Edges texture is applied for a Round Edges effect
• Special handling for rotated normal maps is implemented. Normal maps rotated manually or by the UVW Placement randomization feature no longer render inverted
• The upper limit of the Intensity parameter of Emissive materials is removed

Color Management

• ACEScg color space management implemented. Select the ACEScg RGB Primaries in the color management settings to ensure that V-Ray is rendering in the new color space. Most standard RGB bitmap textures should use the sRGB Primaries option in this workflow
• ACEScg color space support is added to the Color Picker

Finite Dome Light

• Finite Dome parameters added to the Dome light source. It limits the size of the Dome shape and introduces a ground projection that can be adjusted using the Projection Height and Ground Blend parameters

Assets Preview Swatch

• Live preview for Decals implemented
• Sphere swatch preview scene added for material assets. The preview is similar to the one used in Cosmos
• The automatic texture resize is disabled for the GPU asset preview. The material swatch no longer lacks details and appears blurry
• The Environment textures’ preview no longer appears incorrect when the GPU mode is enabled
• The V-Ray typography of the Generic material preview is updated to match the current company branding

VFB

• Panorama viewer implemented. Use the Panorama View toggle in the View menu to enable the new mode. Looking around in this view is done by holding the middle mouse button and moving the mouse. The field of view can be altered by scrolling
• Proportion Guides layer implemented to help you with the frame composition
• Batch image processing implemented. Use it to apply corrections to a set of pre-rendered images
• Flip buttons implemented. Use the quick flip feature to have a fresh eye on the image composition and verify it works in all settings
• Dither colors option implemented in the VFB settings / Render View rollout. Make sure it is enabled to avoid banding with low-contrast gradients
• The VFB configuration including the History state and folder location is preserved between installations
• The Exposure (display only) slider part of the Display Correction’s layer parameters no longer affects images saved from the VFB

V-Ray GPU

• Improved performance and reliability
• Added support for the Lighting Analysis render element
• Improved trace depth limit handling
• Improved round edges rendering quality
• The global trace depth logic used by the GPU engine now matches the one used in Production CPU rendering. Enabling the Render Parameters/Optimizations/Max Trace Depth checkbox ensures that the value specified overrides all corresponding max depth settings in the materials
• The standalone GPU Device Selection tool is updated. The new user interface allows specific devices to be selected for Denoising (should be considered when NVIDIA AI denoising is used). This can help boost rendering performance on systems with more than one GPU
• An issue preventing spotlights from being scatter by the Environment Fog is resolved

Integration

• Rhino 8 is now supported
• V-Ray scene importer implemented. Import any .vrscene file for editing in Rhino. V-Ray shaders are also added to the scene. ‘Unsupported’ shading nodes use an auto-generated UI - still remaining editable. Note that this feature is still in an experimental stage
• Implemented support for Double-sided material in Rhino 7 and Rhino 8
• An issue causing materials from legacy scenes to not get loaded correctly in the current V-Ray version is resolved
• Materials can now be assigned to object faces in Rhino with the Apply to Selection context menu action in the Asset Editor
• An indication of VPR initialization is displayed at the bottom of the viewport
• Displacement modifiers no longer disappear when exporting a Proxy Scene

• The vrayCosmos command is updated. It is now more convenient for an asset ID to be used as a selector. Exact asset names can also be used instead of the ID
• V-Ray textures which are inverted or multiplied are now displayed correctly in the Rhino viewport
• Changing the Focal blur options in Rhino (with the V-Ray’s Depth of Field / Focus Source set to Rhino) is now supported during interactive rendering
• The way Rhino Linear Lights are rendered is improved. The resulting Rectangle light has its Double Sided option enabled
• A number of issues regarding the LODs (levels of detail) of Cosmos assets are resolved. Note that the LODs are only used in V-Ray Vision
• Chaos Vantage is no longer automatically stopped when Rhino is closed
• The vrayMtlFromRhino command is improved to account for per-face material assignments
• When a Binding texture is used the viewport material representation now ignores all other parameters
• V-Ray materials without a Rhino counterpart can now be preserved when opening the project thanks to a new warning message that presents this option. Note that this is a corrupted state which by design should not occur. It is most often achieved when the project is edited without the V-Ray plugin being loaded or in specific rare cases when the File/Import or File/Insert Rhino actions are performed
• The local Environment texture that can be added to native Rhino materials is now supported by V-Ray
• The ‘Reset To Defaults’ material-specific action that can be performed in Rhino’s materials list is now supported. Note that all V-Ray shaders are reset to a gray Generic material

Grasshopper

• Dome light implemented
• Sun light implemented
• Mesh light implemented
• The items in the V-Ray Render Toolbar section are now better organized
• The default file type of the Proxy Mesh component is now correctly set to .vrmesh
• All Color inputs of the V-Ray components now accept color values that exceed 1.0
• Rapidly changing the current frame in the Timeline component during interactive rendering no longer leads to a crash

[konstantin_chaos]

Vision

• A new system for evaluating V-Ray textures is implemented. Most of V-Ray’s procedural textures and texture corrections are now supported in Vision. This is achieved through ‘baking’ which leaves raytraced or camera-based procedural maps still unsupported (Dirt, Falloff, Distance, Edges, etc.)
• Measurement tool implemented. Use the toolbar button or the Z key to enable the tool, then select the two points to measure the distance between them
• Depth of field support added. Change the DOF settings in V-Ray to see an effect in Vision. Note that the defocus amount is limited in Vision
• The Orbit navigation mode hotkeys now match the ones in the host application
• A new handling for materials opacity is implemented. Visual artifacts no longer appear when multiple transparent objects overlap in the frame

• The overall stability and reliability of Vision is improved
• The parameters in the Settings panel are now organized in rollouts
• Hours can now be displayed in the timeline end label
• An issue preventing Vision from working on macOS is resolved
• The default range of the Ambient Light Intensity slider is increased to 200
• The active camera FOV (Field of View) is taken into consideration when calculating the mouse sensitivity. This improves the Vision navigation in specific situations
