Naming Conventions

Fightura tracks every Figura part by:

1. parentType — Figura’s built-in body region (Head, Body, LeftArm, …)
2. part name — case-insensitive match against a built-in alias dictionary
3. Lua override — your script can bind any name to any joint at runtime

If any of these resolve to an Epic Fight joint, that part follows the joint. If none resolve, the part falls through to Figura’s normal render and inherits through its parent.

Epic Fight joints

These are the joint names you can target:

Joint	Position
Root	Entity origin
Pelvis	Hip
Spine	Lower torso
Chest	Upper torso
Head	Neck/head
Arm_L, Arm_R	Upper arm (shoulder pivot)
Hand_L, Hand_R	Forearm and hand
Thigh_L, Thigh_R	Upper leg
Leg_L, Leg_R	Lower leg and foot

Built-in part-name aliases

All matching is case-insensitive. Pick whichever style your modeling tool exports.

Mixamo standard

If you imported a rig from Mixamo, the bones already work:

Mixamo bone	Maps to
mixamorig:Head, mixamorig:Neck	Head
mixamorig:Hips	Pelvis
mixamorig:Spine, Spine1, Spine2	Spine / Chest
mixamorig:LeftShoulder, LeftArm	Arm_L
mixamorig:LeftForeArm, LeftHand	Hand_L
mixamorig:LeftUpLeg	Thigh_L
mixamorig:LeftLeg, LeftFoot	Leg_L
(Right side mirrors above)

Blender Rigify

Bone	Maps to
head, neck	Head
spine, spine.001	Spine
spine.002, spine.003	Chest
shoulder.L, upper_arm.L	Arm_L
forearm.L, hand.L	Hand_L
thigh.L	Thigh_L
shin.L, foot.L	Leg_L
(.R mirrors above)

VRM / VRoid

Bone	Maps to
J_Bip_C_Head, J_Bip_C_Neck	Head
J_Bip_C_Hips	Pelvis
J_Bip_C_Spine, Chest, UpperChest	Spine / Chest
J_Bip_L_Shoulder, UpperArm	Arm_L
J_Bip_L_LowerArm, Hand	Hand_L
J_Bip_L_UpperLeg	Thigh_L
J_Bip_L_LowerLeg, Foot	Leg_L
(Right side mirrors)

Custom names — Lua override

If your part names don’t match any of the above, bind them once in events.LOAD:

function events.LOAD()
  fightura:mapBone("MyTailRoot", "Pelvis")
  fightura:mapBone("LeftSleeveCuff", "Hand_L")
  fightura:mapBone("HornLeft", "Head")
end

The first argument is your part name (or parentType name); the second is one of the Epic Fight joints from the table at the top.

To remove an override:

fightura:clearBone("MyTailRoot")  -- one
fightura:clearBones()              -- all of this avatar's overrides

To inspect what’s available at runtime:

print(fightura:getSupportedBones())  -- list of every built-in alias
print(fightura:getJoints())          -- list of joints in the entity's current armature

Part hierarchy still works

You only need to bind a part if you want its own transform to come from an Epic Fight joint. Children of a bound part inherit through Figura’s normal flow.

For example, if you bind LeftShoulder to Arm_L, child parts named LeftElbowAccessory (with no special mapping) will move with the upper arm automatically — no extra binding needed.
