RHaseltine,the pit does have morph targets along the outer edges. The four sides bend up or down each independently so you will be able to blend it into your terrain in Vue or any other app. I found so far that the Poser default ground plain cutting through the pit with the very same ground textures raised up or lowered down on the y-axis gives a good time laps photography affect that you are talking about. Stretching the pit itself with a morph target creates funny distortions in the walls of the ground textures.
