That can’t be the case as the file would not have worked.
I basically have 2 E3D scenes:
One set to composite and the other as Zbuffer
.
The are now completely different.
If it had always been the case it wouldn’t have worked ☹
It used to be based on layer number, as changing the layer order would mess it all up and change all the values.
Now that doesn’t happen, but they differ across comps.
