Now having independent viewports in LightWave 2015.2, I have the problem that I cannot find a way to sync all viewports again. When working with multiple views and one camera everything works fine. But when I clone that camera and move it, the change is only reflected in the current viewport since they are independent from each other. Changing every viewport option to "current camera" does not lock the option.
I usually work with multiple viewports and often have two viewports which show the same camera view (a smaller one for faster VPR).
