**Map type** – Allows the user to specify whether a bump map or a normal map effect will be added to the base material. 

**Bump map**  
** ** **Normal map in tangent space**  
** ** **Normal map in objectspace**  
** ** **Normal map in screen space**  
** ** **Normal map in worldspace**

**Bump multiplier** – A multiplier for the bump/normal effect.

**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.

**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.
