You mentioned terrain (very non-specific), cover (somewhat less vague), wind (i.e. crossing?), lighting (Not likely to be a factor in testing, or in hunting with a responsible hunter). You wouldn't normally be worrying about completing retrieves during lightening, but rather getting you and your dog to safety. All that taken at face value, let me give you some examples of how factors work in diverting routes.
Flare: An obstacle, like a fallen tree or hay bale, is directly in the path to a blind retrieve. If the dog does not choose to jump over it, but instead run around it, he has been diverted (flaring it). Only one example.
Suction: A recent fallen bird is near or on the route to a blind, and draws the dog offline toward it instead of remaining on the line given by the handler. (suction to the old fall) Again, just one example.
Drift: A crossing wind (say - right to left) blowing across the route to a fall. The dog follows the direction of the wind rather than holding the line; drifting with it.
If some physical element in a set up, especially in or near a route, it is only a factor if it tends to divert dogs by its presence.
