Bump Height
The bump height controls the height of the bump when a positive value is used and the depth of the pits when a negative value is used. The larger the value the more pronounced the bumps will become.

Upper & Lower Clip
The upper clip specifies the maximum height at which the bump will be evaluated. After this the bump will be flat. Similarly, the lower clip sets the minimum height at which the bump will be evaluated and again, below this height the bumps will be flat.

Lower Smooth
The lower smooth controls the shape at the lower part of the bumps. Primarily this control is available with tile type textures where the it controls the shape of the lower part of the tile bevel. Three shapes are shown below. However more varied and extreme shapes can be obtained with values outside the -100 to 100 range.

Upper Smooth
The upper smooth controls the shape at the upper part of the bumps. Primarily this control is available with tile type texture where the it controls the shape of the upper part of the tile bevel. Three shapes are shown below. However, as with the lower smooth more varied and extreme shapes can be obtained with values outside the -100 to 100 range.
