I've just started testing out with cameras but one of the first things I noticed and was expecting to happen was when the tracking starts to loose the general orientation of the pelvis and torso(if you spin around, also very noticable in in greenlaws prop tests) ,
I cant help to wonder if this could be solved easily by having a coloured belt that has an indicator of front and back. It may just be my setup isn't amazing but I cant see how more accurate tracking wouldn't benefit the program and am wondering if there is any plan to improve ipi's tracking and solving in this or any other way?
By the way very cool, Im still in the process of finetuning my 'capture volume' and 'capture suit' but am rather pleased with results, perhaps not production capable but definitely home worthy :)

Suppose I should post an example

Try to set one or two cameras at 2+ meter height. It should help the system to view position of shoulders thus spine position will be detected more accurately.

Ok I'll try and set 2 of the cameras higher up and see how that goes
