The settings on this page enable you to simulate bumps. You must use a texture with this channel. It
is only from the grayscales in this image that the bump map (a height or relief map) is calculated.
Strength
The strength of the bumps. The higher the value, the rougher the surface. If you move the slider to
the left, you can choose negative values to reverse the effect of the bump map — bright pixels then
cause the material surface to indent while darker pixels elevate the height of the surface.
MIP Falloff
Figure 1: MIP Falloff disabled (left) and enabled (right).
You can strengthen the MIP/SAT mapping effect when using bump mapping by enabling MIP Falloff.
The bump mapping is then reduced the further the surface is from the camera.
Texture, Mix Mode, Mix Strength
For details on these settings, look up ‘texture settings’ in the index.
Figure 2 shows an even surface viewed from the side. The surface has a uniform brightness. However,
if you use a bump map for the same surface, CINEMA 4D interprets the brightness values of the picture
as height values for the surface (Figure 3).
