The Generic material settings are organized in Basic and Advanced modes. You can switch the mode from the toggle button under the Preview Swatch or globally from the Configuration rollout of the Settings tab.

An Add Layer button is provided for some V-Ray materials, including Generic. You can select an additional layer that can add up to the appearance of the material. For more information, see theLayers section on the Materials page.

From the Add Attribute button, you can select additional attributes that can add up to the appearance of the material. For more information, see the Attributes section.

UI Text Box
typetip
Holding down Ctrl (or Cmd on macOS) while having the Add Attribute or Add Layer menu open, allows selecting multiple entries without closing the dropdown.

The context menu of the Color slot provides options to Copy and Paste, as well as to Reset the color.

A Reset option is provided in the context menu of each Number Slider. You can reset the slider value to the default one.

The blue indicator next to a rollout () indicates that the lead parameter of this rollout, which affects the final appearance of the material, is changed.

Back Material– Defines the material V-Ray uses for back side faces as defined by their normals.

Translucency – Determines if the front or the back side of the material is more visible in the rendering process. By default this value is 0.5, which means that both sides are equally visible. When this parameter is closer to zero, the material facing the camera is more visible, when it is closer to one, the back material is more visible. A texture can be used to control the variation of the effect.

Mult. by Front Diffuse – When enabled, the translucency is multiplied by the diffuse of the front material.

Bump

Mode/Map6 – Specifies the bump map type.

Bump Map – A height map should be used.
Normal Map5 – RGB map should be used with this option. Note that in most cases the normal map bitmap color space should be set to Linear to ensure correct results.
Local Space Bump – A height map should be used. Unlike the standard Bump mode, in this case the height is not measured in scene units. It is only determined by the raw texture values. Scaling objects will not affect the local space effect. This option has to be selected for the round edges effect (Edges texture used as bump).

Amount6 – Multiplier for the bump/normal map.

Outline

The Contour Outline attribute is available only when the engine is set to CPU. It is currently not supported for GPU.

Line Color – Specifies the color of the outlines.

Opacity6 – Specifies the opacity of the outlines.

Normal Threshold – Determines when lines are created for parts of the same object with varying surface normals (e.g. at the inside edges of a box). A value of 0.0 means that only 90 degrees or larger angles generate internal lines. Higher values mean that smoother transitions between face normals can also generate a line. Setting this value to 1.0 fills curved objects completely.

Overlap Threshold – Determines when outlines are be created for overlapping parts of the one and the same object . Lower values reduce the internal overlapping lines, while higher values produce more overlap lines. Setting this value to 1.0 fills curved objects completely.

Width – Specifies the width of the outlines.

Inner Line Control – Enables a separate control for the inner edges.

Inner line Color – Specifies the color of the inner lines

Inner Width – Specifies the width of the inner lines.

Some of the global parameters have an effect on all materials with Contour Outline attribute. These parameters are Width Type, Trace Bias, No Inner Edges, Visible in Secondary, and Compensate EV.

Visible to Camera – When enabled, makes objects using this material visible to the camera.

Visible to Reflections – When enabled, this option makes objects using this material visible for to Reflection rays.

Visible to Refractions – When enabled, this option makes objects using this material visible for the Refraction rays.

Cast Shadows – When disabled, all objects with this material applied do not cast shadows.

  • Materials with Normal opacity mode are now migrated to Stochastic opacity mode.

  • The Highlight Glossiness parameter 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 VRayMtl/VRayBRDF 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 VRayMtl Generic and other V-Ray compliant materials.

  • VRayMtl The Generic material can produce reflections/refractions for matte objects - see Wrapper Material | MtlWrapper.

  • The 2D mapping method ignores the Tiling parameters specified in the textures themselves.

  • The 2D mapping (landscape)  method only supports one UV mapping channel.

    notes
    Having a very large number of scene objects using materials with 2D Displacement may substantially prolong the geometry compilation phase of the rendering process.

  3. Prior to V-Ray Next, Update 1 the Fog Scattering section was known as Translucency.

  4. With V-Ray 5, PBR layers are converted to regular VRayMtl material layers.

  5. 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.

  6. 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.
