Which is a "correct way" of defining selections.

1) overlapping so that entities belong to several selections simultaneously -> otochlaven (gun) is also included in selection otocvez (turret) etc.

2) separate so that each part belongs only to one selection

Both seem to work if skeletons are ok. Common sense would pick option 2 (then there would not be any unnescessary calculations as the model is animated), but BIS example vehicles (which I downloaded) use the method 1 (the overlapping selections)...???
