The Bump Material gives the ability to add bump map and normal map effects when using any material.

Simply apply a Bump Material to an object to add additional bump or normal map functionality. Stacking multiple Bump Materials together can create a more complex surface material by allowing the use of several bump and/or normal maps together easily.







Base Material  – Allows the user to select the base material to which the bump/normal effect will be added.



Bump and Normal Mapping




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

Advanced Options

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

Can be Overridden – When disabled, the material is not overridden by the Material Override option in the Render Settings.
