The composite relief can be built from either one of the two layer stacks in the model; one representing the front surface of your piece, the other its back. Use the
Transfer Relief Layer
button to transfer a relief layer from one stack to the other.
and
Toggle Back Relief
buttons on the
3D View toolbar to concurrently view the composite relief resulting from both stacks.
When you transfer a relief layer from one stack to the other, the composite relief resulting from both layer stacks is affected. It is prudent to check the composite relief shown in the 3D view whenever you transfer a relief layer.
In every new model, each stack includes an empty relief layer. There must always be at least one layer in each stack.
To transfer a relief layer to the opposite layer stack:
beside the
Front Relief or
Back Relief item to display either the front or back relief layer stack.
to transfer the currently active layer to the opposite layer stack.
