Transparency – Controls the intensity of the Transparency.

Diffuse Color – Controls the intensity of the diffuse component color of the shader.

Primary Spec. Color – Controls the intensity of the Primary Specular color component, which corresponds to the light reflected off the outer surface of the hair strands.

Secondary Spec. Color  – Controls the intensity of the Secondary Specular color component, which corresponds to the light reflected off the back surface of the hair strands.

typeinfo

In this mode complex texture networks are baked to a single image used as a viewport preview. Differences between the rendered result and the viewport preview may occur due to the fact that only the texture confined within the 0 to 1 UV square is baked. This affects most procedural patterns and textures with custom UV placement configuration. Raytraced and Tri-planar textures are not supported.

...

It is recommended to save all raw bitmap buffers (textures embedded in SketchUp like SketchUp library materials textures) to disk before activating the Bake mode to preserve them.

The viewport resolution of procedural textures can be set globally from ||Extensions|| > V-Ray > Preferences > Viewport Texture Resolution option.

Custom – A custom texture slot is bound to the base app material.

Viewport Texture – The selected texture is bound to the base app material. Keeping this slot empty in Custom mode shows a Helper Texture in the viewport.

If a Generic material contains multiple layers, only the top-most one is regarded in Auto binding mode.
