Connect a material into the Bump node to add additional bump or normal map functionality. Stacking multiple Bump nodes together can create a more complex surface material by allowing the use of several bump and or normal maps together easily.

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

Bump Map
Normal map in tangent space
Normal map in object space
Normal map in screen space
Normal map in world space
From texture bump output
Explicit

Texture Map – Specifies the bump/normal map that is used.

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

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 enabled, V-Ray considers the bump maps when rendering shadows produced by objects with the bump material applied to them.
