I remember from a long time ago that an Advanced Model Support was available , giving more possibilities to model makers , and to use their model you had to download an install that AMS too yourself (just an umod).
One of the first time i heard this 2 words "skeletal animation" was at the time AMS was released , but i never tried to understand what it was.
So does INF2.9 has the AMS features in it with the install by default , or do we need to download of this AMS , as several advanced models needed ?
