The Erase tool
removes sculpting from a layer in the areas you stroke. Any sculpting
on the original base mesh remains unaffected.
Note You can create a
layer prior to any sculpting and use layers for all your sculpting
until you need to merge or flatten them. In this way, the base mesh remains
unaffected if you need to revert to it.
Select the Layers window
and ensure the display button at the top is set to Sculpt.
Click the layer whose sculpting you want
to erase, ensuring that the layer is both visible and unlocked.
Note the subdivision level on which the
layer was first created as well as the currently displayed subdivision
level, then press either the Page Up or Page
Down key to display the subdivision level that matches
the layer subdivision level.
Select the Sculpt Tools tray.
Select the Erase tool,
and stroke on the model in the areas you want to erase.
