This section concerns both normal maps and standard bump map. It allows control of the feature on both the coating layer and the base layer.
→ Type
Specifies the type of the bump mapping desired – either Bump Map or Normal Map, Normal Map or Displacement Map. In the case of a Normal Map, a color is expected in value and will be used as the normal mapas a value, it can be encoded in the style or DirectX or OpenGL. In case of Bump Map or Displacement Map the the shader will only consider the R value. Displacement maps can be interpreted as
→ Value
A colour input specifying bump direction (Normal Map) or intensity (Bump Map / Displacement Map).
→ Intensity
Specifies how intense is the the bump mapping effect. A value of 0 means that normals will stay unchanged whereas a value of one will affect normals with full range.
→ Layers Affected
Select to apply bump to the coating, base layer or both layers (default). Has no effect when Type is set to Displacement Map
