If I’m understanding you correctly Wolpi, you can parent the whole scene in a Null object, and then you rotate the Null and everything parented to it will turn with it.
I’ve attached a screenshot of the Null icon below. I’m using DS 4.0 Pro and I’ve customized where my tool icons appear in the UI, so yours may be located somewhere else.
All you need to do is select every thing you want to move together in your Scene Tab, click on the Null icon, and when the dialog box opens, you can name the Null as you wish, and then click on the Parent Selected Item(s) to Null, and click the Accept button.
Then you would select the Null in your Scene Tab and using the Parameters Tab, you can rotate it as you wish, and everything will move together.
