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.
Local Space Bump
Amount – A multiplier for the bump/normal map.
Normal Map Type – Specifies the normal map.
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.
