Materials with Normal opacity mode are now migrated to Stochastic opacity mode.
The Highlight Glossiness parameter is a legacy plugin. It is migrated from previous versions; however, if it is disabled, the row is hidden and its value is set to 1.
Use the Generic material whenever possible in your scenes. This material is specifically optimized for V-Ray and often GI and lighting is computed much faster for V-Ray materials than for standard materials. Many V-Ray features (e.g. light cache, render elements ) are guaranteed to work properly only with Generic and other V-Ray compliant materials.
The Generic material can produce reflections/refractions for matte objects - see Wrapper.
The 2D mapping method will ignore the the Tiling parameters specified in the textures themselves.
Having a very large number of scene objects using materials with 2D Displacement may substantially prolong the geometry compilation phase of the rendering process.
Prior to V-Ray Next, Update 1 the Fog Scattering section was known as Translucency.

With V-Ray 5, PBR layers are converted to regular material layers.
With V-Ray 5, update 2, all Normal maps of newly-created materials are calculated in Tangent space. The options for Object/World/Screen space normal maps are now considered legacy options. They remain unchanged in materials from older scenes unless the materials are updated to a non-legacy bump mode. In this case, the legacy options cannot be restored back.
When a Bitmap texture is mapped in this slot, its color space is automatically adjusted. Copy-pasting, replacing or wrapping a texture does not trigger this automatic adjustment. It is reserved solely when creating a Bitmap in the specified material slot.
