Thanks for the reply. Yes that is what I meant by layer states.
Can different Scenes save different combinations of layer visibility?
I was not able to do that?
In other words I set up one Scene with A,B,C,D layers on.
Then I set up a different Scene with W,X,Y,Z layers on.
When I went back to the first scene ABCD layers were off and
WXYZ layers were on. …?
