I work with a secondary window in the 3D view to see the terrain as I work. I often will edit a node’s parameters, and will look at the terrain as I adjust the sliders to see its effect. I often want to see how the change will effect the the terrain from different perspectives. However, when a node’s dialog is up, the 3D viewport locks and the camera cannot be orbited or moved at all. This means I find myself constantly ping ponging between adjusting parameters and then closing the dialog to change the view. The camera locking seems arbitrary and slows down the workflow. It would be great to allow camera navigation in the 3D viewport even when dialogs are up! I think its one of those small things that would really improve the editing experience. Thanks for considering this.
