backward z order compatibility with digital pro

In scene settings under advanced options there is a check box called “backward z order compatibility with digital pro”. Any one know what this is for?

thanks!

If you never worked with Digital Pro or will not have to use Digital Pro projects, this setting will not affect your work.

I do not remember the exact values but, in Digital Pro, elements were considered at the same Z depth when there was, let’s say, a 0.0001 Z difference between them. Starting in Harmony 7.8, this value was changed to something like 0.001 Z…

So, if you get a Digital Pro scene in Harmony 7.8, there is a chance that elements considered on the same Z were not considered on the same Z anymore. This option was telling Harmony to use Digital Pro precision regarding Z axis.

As I said, I do not remember the exact values but, I’m sure you’ll get the picture…
