Investigation

There are 2 different TRIA files in Oni. This one, used by most TRCM :

Bone 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12
Parent 00 00 01 02 00 04 05 00 07 08 09 09 0B 0C 0D 09 0F 10 10
Child 01 02 03 00 05 06 00 08 09 0A 00 0C 0D 0E 00 10 11 12 00
Sibling 00 04 00 00 07 00 00 00 00 00 0B 0F 00 00 00 00 00 00 00

and this other one, used by extra-low-LOD (i.e. force-shield) TRCM of male scientists :

Bone 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12
Parent 00 00 01 02 00 04 05 00 00 00 00 00 00 00 00 00 00 00 00
Child 01 02 03 00 05 06 00 00 09 0A 00 0C 0D 0E 00 10 11 12 00
Sibling 00 04 00 00 07 00 00 00 00 00 0B 0F 00 00 00 00 00 00 00

The "normal" one gives you a normal hierarchy :

0 + 1 - 2 - 3 - X
  + 4 - 5 - 6 - X
  - 7 - 8 - 9 + 10 - X
              + 11 - 12 - 13 - 14 - X
              - 15 - 16 - 17 - 18 - X

While the "low-LOD-doctor" one gives you a weird hierarchy :

0 + 1 - 2 - 3 - X
  + 4 - 5 - 6 - X
  - 7 - X
8 - 9 + 10 - X
      + 11 - 12 - 13 - 14 - X
      - 15 - 16 - 17 - 18 - X

(neglecting the fact that parent links are null for the upper part of the body). It would look like chest is directly parented by the root bone, but then it's not a sibling of pelvis... so it's completely loose.

The associated TRTA is also weird.

  • The only difference between the extra-low-LOD and the mormal-LOD TRTA of male scientists is the offset of chest.
  • In the normal-LOD TRTA, the offset is (1.4, 0, 0), whereas in the extra-low-LOD TRTA, it is (0, 0, 13.5).
  • This again seems to indicate that chest is parented by the root bone if at all...
And indeed...
If you specify e.g. Kerr's TRBS to use nothing but the extra-low-LOD TRCM
(and its TRTA and TRIA, which is the whole point), you'll see weird stuff.
(Kerr's inane upper body floating around, control limited to Kerr's legs and the weapon, if any)
Conclusion
Generally speaking, the TRTA and TRIA of low-LOD TRCM are ignored.
Any body in the TRBS uses the TRTA and TRIA of the extra-high-LOD TRCM
(i.e. the TRCM linked to at 0x18 in the TRBS)
