Hi.

poser.Scene().Changed() tells you if the scene has been changed
poser.Scene().SetChanged() sets the scene as changed

poser.Scene().DocumentPath() returns the path of the current scene

To access the subdivided geometry you can use this type of code:

# a = Actor
if (a.IsBodyPart() and a.ItsFigure()):
  if ((a.ItsFigure().SkinType() != poser.kSkinTypePOSER) and a.SubdivideWithFigure()):
    continue
  else:
    if (not (a.IsProp())):
      continue
g = a.SubdivGeometry()

For the new method about the camera and light changed see the addon baseclass source that is installed with Poser. 

Hope this helps.

Paolo
