+==Investigation==
+There are 2 different TRIA files in Oni. This one, used by most TRCM :
+{|border=1 cellspacing=0
+!Bone
+|00||01||02||03||04||05||06||07||08||09||0A||0B||0C||0D||0E||0F||10||11||12
+|-
+!Parent

+!Child
+|01||02||03||00||05||06||00||'''08'''||09||0A||00||0C||0D||0E||00||10||11||12||00

+|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 :
+{|border=1 cellspacing=0
+!Bone
+|00||01||02||03||04||05||06||07||08||09||0A||0B||0C||0D||0E||0F||10||11||12

+|}
+The "normal" one gives you a normal hierarchy :
++ 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 :
++ 1 - 2 - 3 - X
+   + 4 - 5 - 6 - X
+   - 7 - X
+- 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 looks like '''chest''' is directly parented by the ''root'' bone.
+The associated [[OBD:TRTA|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.
+;And indeed...
+:If you specify e.g. Kerr's [[OBD:TRBS|TRBS]] to use nothing but the extra-low-LOD [[OBD:TRCM|TRCM]]
+:(and its TRTA and TRIA, which is the whole point), you'll see ''weird'' stuff.
+:(Kerr's 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)
