* "istg" is the inverse staging number (highest number triggers first) * "dstg" - something to do with staging... it appears you are correct with istg the way it looks to me is: istg : the stage in which part is activated (the orange stage groups on the side of your screen) dstg: the stage in which the part is attached in relation to decouplers; decouplers appear to get there own stage so the object attached will be 1 more than the decoupler example: istg 0 = { dstg 0: command module 1 fuel tank 1 engine 1 dstg 1: stack decoupler } istg 1 = { dstg 2: fuel tank 2 engine 2 } hope that makes sense
