Bob, There is no control for that just yet. Work is in progress to provide the full complement of light controls. If you are working in builting mode, you can resort to python as follows.
lights = GetActiveView().GetRenderer().GetLights() for i in range(0, lights.GetNumberOfItems()): lights.GetItemAsObject(i).SetLightTypeToSceneLight() Note: the light position bug in 5.1 that Alan was referring to had the effect of making making the light positions fixed (scene lights in vtk terms). In 5.2 that was corrected and now they are camera relative lights that move with the viewer as they do with GL rendering. hope that helps David E DeMarle Kitware, Inc.
