This page provides information about Bump Attribute in V-Ray for SketchUp.
Overview
An Add Attribute button is provided for some V-Ray materials. Select additional attributes to add up to the appearance of the material. For more information see the Add Attributes on the How to Work with Materials page.
Parameters
Mode/Map – Specifies the bump map type.
Bump Map – A height map should be used.
Bump Texture Channel – Some V-Ray textures have a special bump channel output that can be used here. It is most commonly used for Round Edges effect. Edges texture is used as a bump.
Normal Map – RGB normal 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.
Amount – Multiplier for the bump/normal map.
Delta Scale – Specifies a scale for sampling the bitmap when using bump mapping. The exact value is calculated automatically by V-Ray, but can be scalled here.
