Page History
This page provides information on how the latest version of V-Ray handles scenes saved with previous versions of V-Ray.
Grasshopper Rig Components
...
Starting with V-Ray6.10.10, the migration of Rig components, created with V-Ray 6.10.00, requires parameter rewiring.
Overview
...
V-Ray 6 adds a number of rendering optimization features. However, for compatibility reasons, some features and workflows have been adjusted and are discussed in detail below.
V-Ray for Rhino is not forward-compatible, meaning projects done with V-Ray 6 are not guaranteed to work with V-Ray 5 or older versions. If a project is opened using an older V-Ray version than the one it was created with, a prompt message will offer wiping all V-Ray data to ensure file stability.
First-time use
...
When opening Rhino for the first time right after installing V-Ray, some or all assets of the scene you load may be missing.
...
The Portal Light option in V-Ray Rectangle light is now a legacy option and is no longer exposed in the UI. Rectangle lights in files saved with previous V-Ray versions and this option enabled will still have it available. Regardless, for best performance consider disabling it and using the Adaptive Dome Light option instead.
Materials
...
Starting with V-Ray 6, the Fresnel formula is now calculated more precisely. As a result, some materials, mainly metallic ones, may render slightly differently (with more physically-accurate reflections).
...
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. For more information, go to Enscape Compatibility.
Special Objects
...
Starting with V-Ray 5.20.01, V-Ray special objects (Fur/Clipper/Displacement/Mesh Light/Scatter) are not deleted from the Asset Editor, when the last item with the corresponding special object assigned to it, is deleted from the viewport.
