I've fownd how to resize any part very easily!: To rescale any part to 1/4 of their original size (you can of cours rescale it to whatever you want): 1- Add "rescaleFactor = 0.25" in your .cgf 2- Enjoy! the downside is that you will have to rebuild the nostromo because, you will see, it won't look exactly the same Sorry if i made mistakes but i'm not english!
