Bump

Image RemovedThe Bump node allows you to add bump map or normal map effects when using any material.

Bump Delta Scale - scale for sampling the bitmap when using bump mapping. The exact value is calculated automatically by V-Ray, but can be scaled here.

Bump Shadows - when this option is checked V-Ray will consider the bump maps when rendering shadows produced by objects with the bump material applied to them.

Type - allows the user to specify whether a bump map or a normal map effect will be added to the base material. 

• Bump - normal bump map
  
• Normal (Tangent) - normal map in tangent space
  
• Normal (Object) - normal map in object space
  
• Normal (Camera) - normal map in camera space
• Normal (World) - normal map in world space
• From Bump -
  
• Explicit Normal -
  

Base Mtl - allows you to select the base material to which the bump/normal effect will be added.

Color Texture - you can use this slot to connect any 8bit texture

Float Texture - you can use this slot to connect a texture in a floating point format

Bump Tex Mult Tex -a multiplier for the strength of the bump/normal effect

Normal Uvwgen - connect a mapping node here.

This node will flip the normals for back-facing surfaces with this material assigned.
