Exporting mods from the alpha version.

Well, that's the standard "T" pose, but why does it turn out that way?! If I remember correctly, the bone names haven't changed...

I have two assumptions on this topic:
1. The bone positions don't match the model.
2. When the gr2 geometry is exported to the game format, it is "optimized" by the editor specifically for the specified skeleton, which is why the model will not work correctly with other skeletons, even if they have all the bones 1 to 1.
In general, here is the model of that paladin with a skeleton from the alpha version.
