While it's best to have an uncluttered space, in many situations you can use a area that isn't 'clear' if you have also recorded some clean video to help iPi separate the background from the performer. (Many examples of successful tracks using 'unclear' backgrounds can be found elsewhere in the user gallery section.) The main thing is to avoid reflective surfaces (windows, glossy floors, large stainless steel appliances and fixtures, etc.,) because they may confuse the tracking system with distracting reflected motion or lights. Even an active screen saver on a computer monitor can be mistaken for a 'maglite'. The point is, however, you can usually correct these types of problems if you know what to look for. It's also important to light the performer as evenly as possible, because dark shadows moving across the body may also confuse the tracker.
That said, it is possible to construct the scene manually. An artist I work with had done this before, but the result was not as accurate as allowing iPi create its own 3D environment. IMO, I would try to adapt the physical shoot space to be more iPi-friendly as it's best to allow iPi Studio to generate it's own 3D environment. If this isn't possible, I would find a different space (I tried three spaces before deciding on an ideal space,) or I would switch to a Kinect which works in almost any small area even if it isn't 'clear' and isn't affected by shadows.
