Date - Dec 7, 2023

Scatter

The scattering toolset is extended in a number of ways. Major workflow changes like the new scattering modes, area modifiers, and lights scattering are combined with numerous small improvements
Bounding box scattering mode is implemented. Note that it uses the object’s bounding box instead of the actual volume boundaries
Curve scattering implemented. Scatter objects along a path with additional control over the instances’ spacing and positioning to help produce organic results
UV Grid surface scattering mode is implemented. In this mode instances are distributed on the surface in a grid pattern. The grid position is determined by the texture/UV mapping of the host surface
Area modifiers implemented. Limit the scattering area based on mesh or curve proximity. Note that the modifier’s projection onto the host’s surface is used instead of its actual physical location
New transformation settings implemented. The new random transformation parameters provide finer offset, rotation, and scaling controls
Light Scattering is implemented. Light sources can now be added as guests to Scatter and instantiated around the scene. Note that a big increase in the scene lights count may significantly increase render times
The way Scatter is handled internally is updated. V-Ray scenes with scattering are now significantly smaller in size and can be uploaded for Cloud rendering in an optimal way

Cloud one-click submit workflow

Cloud submit window is implemented. It enables a new and more intuitive workflow for submitting scenes to be rendered on the Chaos Cloud. There is no longer need to navigate to an external web browser window to submit the project for rendering
The export and render steps from the Cloud submit process are no longer separated by a manual action

VFB

Chromatic aberration effect implemented. This new feature is part of the Lens Effects and simulates the real-world phenomenon of light rays being focused at different points depending on their wavelength
A shortcut that helps with enabling the VFB history feature is implemented
Folders can now be added to the layers stack even when in Standard / RGB source mode. This helps with the layer organization and unlocks new compositing possibilities
A plain color can now be specified in the Background layer
Mask previews can be now copied from VFB to the clipboard
A number of additional small UX improvements streamline the compositing workflow

IES Light improvements

Cosmos light sources containing IES lights can now be imported
IES Light intensity is now automatically derived from the .ies file at creation time or when the profile is changed
The UI of the IES Light is simplified. The Intensity value is always enabled. Resetting its value (via the right-click menu) sets the intensity back to the one from the .ies file
Light shape menu implemented. It specifies which aspects of the light emission and shadow casting are affected by its area shape and size

V-Ray GPU

Enmesh assets can now be rendered with V-Ray GPU
Animation texture caching is implemented. Bitmap files no longer have to be reloaded for each animation frame resulting in lower render times
An issue preventing the rendering of Bitmap Image Sequences is resolved
An issue preventing the render process from starting when specific materials are present in the project is resolved

Integration

The V-Ray scene importer now converts all raw bitmap buffers to regular image files on disk before importing which speeds up the process significantly
Export of multiple cameras is implemented. All Standard or Named views can be exported to a .vrscene via the vrayExportVRScene command. When using Chaos Vantage via Live Link all camera views from the Rhino project are loaded
All Geometry instances are now imported as block instances via the V-Ray Scene Importer
Packing a project that contains multiple texture files with identical names is now handled in a better way. Only one file is packed if the file contents also match. If the files are different an error message is displayed and the process is aborted. Conflicting file names are expected to be manually edited before using Pack Project again
V-Ray now takes into account the visibility state of Enscape assets
The ‘vrayShowVFBOnRender’ command is removed and its function is moved to the ‘vrayShowVFB’ command

Improved viewport materials

A way for displaying most procedural textures as well as procedural texture corrections in the Rhino viewport is implemented. This new default behavior substitutes the generic texture helpers previously employed for mapping adjustments. Differences between the rendered result and the viewport preview may occur due to the fact that only the boundaries of the first texture in the network are respected when baking or due to the fact that some procedural textures can not be baked into a 2D image (like 3D or ray-traced maps)
