V-Ray Material Builder

The V-Ray Material Builder node is a container that allows you to create a variety of V-Ray materials. By default, it creates a BRDFVRayMtl connected to a V-Ray Material Output node. From here, a variety of V-Ray nodes can be created such as BRDF and utility material nodes, textures, mapping nodes, and atmospheric effects.

This tab specifies how the following parameters are rendered in Houdini's viewport.

UV Set Name – Specifies the UV Set Name.

Diffuse Texture – Selects a diffuse texture from a list of all available textures within the V-Ray Material Builder. The list contains only ImageFile textures. 

Opacity Texture – Selects an opacity texture from a list of all available textures within the V-Ray Material Builder. The list contains only ImageFile textures. 

Reflection Texture – Selects a reflection texture from a list of all available textures within the V-Ray Material Builder. The list contains only ImageFile textures. 

Metalness – The metalness of the default V-Ray Material node inside the V-Ray Material Builder. If a new V-Ray Material is created within the V-Ray Material Builder, its metalness must be referred to this parameter in order to be rendered correctly in Houdini's viewport.

Roughness – The roughness of the default V-Ray Material node inside the V-Ray Material Builder. If a new V-Ray Material is created within the V-Ray Material Builder, its roughness must be referred to this parameter in order to be rendered correctly in Houdini's viewport.

Enable – Enables displacement.

Displacement Texture – Controls how the displacement looks in Houdini's viewport. 

Scale – Controls the displacement scale.

Offset – Controls the displacement offset.

Method – Specifies the displacement method.

Vector Space – Specifies the vector space from UV Tangent, Object Space, and World Space.

Up Vector – Specifies the UV Vector.
