No, I am using the DirectionsRenderer to display the routes on the map, but I am handling the display of instuctions with my own function. The basic problem seems to be that calling setRouteIndex(1) or setRouteIndex(2) on the DirectionsRenderer object before calling setDirections(result) has no effect -- the DirectionsRenderer still renders route 0 on the map, even though calling getRouteIndex shows that the route index has been set to 1 or 2 rather than 0. I am able to display the instructions for the alternate paths by accessing the alternate routes in the result object, but I can't get DirectionsRenderer to render the alternate paths on the map.
Your answer will be helpful if I have to resort to rendering the paths on the map myself.
