Orientation and Snow Puddles filters are not really related but are covered here as the "odds and ends" of the filter selection.
Orientation is a world space filter that allows material effects to be distributed according to a strict East West orientation, this feature is somewhat inflexible and for this reason, of little practical use, since it requires that the entire scene is orientated around the position of the filter. It is a "special" scene that is built around one particular filter.
The purpose of Snow Puddles, should be apparent from the name. By being so very specific in the way it functions, it is clearly going to be of only limited use.
Simply knowing how these filters operate in theory should be enough to tell you when you will need to call upon them.
