Hi Dan, The getMatrix/setByMatrix methods in the CamaraManipulators might be convinient and sufficient for switching between some manipulators but there are too many settings in some of the manipulators to be able to set it purely from a 4x4 matrix so the manipulator has to make a guess at what might be intended. For instance a manipulator that uses a look distance, centre of rotation and look vector direction isn't able to compute the look distance from a 4x4 matrix, there simply is too my unknowns for the constraints available. So it's not a bug but a mathematical limitation.
