@VendorX: Apparently you have even less idea what you're actually doing (if any) or asking about, considering that you don't understand even such basic things as explained in the topic.
I thought that we have some kind of discussion here about possible interpretations of data - for example, why there are three FPackedNormal here, which is more UE3 like, or how scaling may actually work, like missing BoundingBox on parsing - but it seems you just wanted a perfect solution for your own purposes without providing your own results. As I see now, it's quite pointless to share any kind of findings or possible ways to interpret data with you, thus the topic is locked now.
If someone want to submit umodel related issues for the game, there is
another topic for this and other Splinter Cell games.
