Bump

This layer allows you to control bump of objects. Bump is a technique for adding detail to your scene geometry without having to model it first. The concept is very similar to material displacement. However, bump is a shading effect that only changes the appearance of a surface, while displacement actually modifies the surface.

The bump layer also accepts all kind of shaders, also layered combination, at image below we use the 3rd party plugin EnhanceC4D Shaders.

Map Type - here you can define type of texture map file, simple image texture or normal map in different space.

Texture Map - here an image texture or shader can be defined.

Invert - This option simply inverts the Texture Map, so bump is reversed.

Bump amount - the amount of bump. A value of 0.0 means the object will appear unchanged. Higher values produce a greater bump effect. Intensity of the bump is sets in really world units, thous units are taken from the c4d units of the file, if you change the units there also the bump size changes accordingly. Bump amount value can`t be negative.

Bump Shadows - Activate it for best reality shadows of object.

Bump Delta Scale - YYY

Map Preview Size here you’ll find entries from 64x64 (16 KB) to 4096x4096 (64 MB). The value controls the internal resolution of the map — the higher you set this value, the more detailed the map will be in the viewport. The value has no effect on the rendered result.Proceed with caution when increasing the Map Preview Size. Higher settings require more RAM and increase the filesize of the CINEMA 4D scene. OpenGL is also affected because the map previews must be loaded into the graphics card’s memory.
