2d_bump_from_height is a modifier map that requires a value map as a parameter. The values in this map are interpreted as representing the height of a bump map. The lower values are interpreted as valleys, with the higher values as peaks.
Once the bump map is created, it often is necessary to adjust the height parameter to achieve the effect that is wanted.
In the example, the value map (a) (a 2d_value_concentric map plugged into the modifier value_stripe_map) on the left turns into the bump map on the right (b) when it is plugged into 2d_bump_from_height.
2d_bump_transform_map
2d_bump_transform_map is a modifier map used to transform a 2d
bump map.
The sliders are as follows:

Once the bump map is created, it often is necessary to adjust the height parameter to achieve the effect that is wanted.
In the example, the value map 3d_value_noise (a) on the left turns into the bump map on the right (b) when it is plugged into 3d_bump_from_height.
3d_bump_transform_map
3d_bump_transform_map is a modifier map used to transform a 3d
bump map, which should be plugged into the bump_map parameter.
The sliders are:
