In the Layers window,
select the layer whose sculpting you want to modify.
Double-click the layer’s Opacity value and
enter a new value or drag the opacity slider keeping in mind the
following:
Increase the Opacity setting to
amplify the sculpting on the selected layer.
Decrease the Opacity value
to reduce the sculpting on the selected layer.
Set the Opacity value
to a negative number to invert the sculpting on the selected layer.
NoteBy default, the Opacity setting has
a range between 0 and 100. You can enter positive or negative values
outside this range to amplify or invert the information stored on
the layer.
