first screenshot shows camera sync on. When I turn off the sync (to work on things in Archicad and move around the camera in Archicad), Enscape does not keep the view (second screenshot). Why is that?
Enscape has its own FOV setting, when Enscape is synced with Archicad it’s using the FOV settings from Archicad. The camera is in the same position, you just need to adjust the FOV settings in Enscape to match Archicad when you exit camera sync.
Not exactly an ideal solution, but a solution nontheless.
