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.
