pShapeRoot->getVolume(false).getInstance().setStatic (true);
pShapeRoot->getVolume(false).getInstance().setValid (true);
pShapeRoot->getVolume(false).getInstance().setInfinite(true);
should work, (haven't tried the inifinite part) but if you extend your
volume and than do the setStatic and setValid calls it should stay as
big as you made it (that part I have tried ;-) ).
