Vray 4.2 Sketchup 2020 Review
The underlying shading structure of all scene materials has been completely reworked. Advanced material attributes can now be added or removed on demand without cluttering the material properties panel. For example, translucent properties can now be added directly to a standard V-Ray material by simply clicking "Add Attribute" and selecting "Translucency" – making it nearly one-click to create lamp shades. Layer modes were also improved, with flakes and random flakes integrated as layers rather than separate materials.
You can open files made in older V-Ray versions, but they may need minor adjustments to materials. Vray 4.2 Sketchup 2020
