Woah that is an older graph with some out-of-date nodes. Apologies for that. Some of the additional issues with it might be the fact that steamnodes is outdated and some of my original nodes in the graph are as well.
Here is how I would actually go about doing that these days:
- Get viewports with ordered selection (to separate the main from the subsequent viewports)
- Turn off all categories except for a consistent one (Project Base Point is decent)
- Set the box centers with the newer Rhythm node. (Viewport.SetLocationBasedOnOther)
- Reset the temporary hide/isolate of the project base point.
and the graph in action:
and the graph itself:
ViewportCentering.dyn (39.9 KB)
Aside from that thought process I would maybe consider having a “Viewport Centering Scope Box” in my project and set all the views crop region to that Scope Box prior to running. That is probably the most stable and consistent way to handle this.
