OOF2: The Manual
Layers
that display the same object can be grouped together
into a LayerSet. For example, a Skeleton
might be displayed by drawing its edges
and by filling each Element
according to its
material
color. If these two Layers
are in one LayerSet
, then
they will always refer to the same Skeleton
. Changing the Skeleton
of one Layer
will also change the Skeleton
of the other Layer
.
