Hi, unless I'm missing something here the line should be u.getViewingPlatform().setNominalViewingTransform();
where u is the simple universe. Out of interest what happens when you pass or set the viewPlatforms or equivalent with a new Transform3D which for example is what I do when wanting to reset the viewTG to its original position (assuming that the origin-without any rotation applied is the used as the initial view start sequence).
