Differences in Notetrack lists

World at War and Black Ops by Treyarch differ a little bit from the original XANIM_EXPORT version 3:

CoD5

All XANIM_EXPORT files have an empty notetrack list, the nodes are separately stored as *.NT_EXPORT:

NUMKEYS 2
FRAME 29 "knife_stab_plr"
FRAME 43 "knife_pull_plr"

• NUMKEYS number of notetrack nodes
• FRAME description:
  • Frame number
  • "name string"

CoD7

At the bottom of all XANIM_EXPORT files you find this instead of a regular notetrack list:

NUMKEYS 0

If there are notetracks for an animation, they are separately stored as *.NT_EXPORT, which you have to specify in AssetManager to convert notetracks.
