A humanoid [SkeletonProfile] preset. A [SkeletonProfile] as a preset that is optimized for the human form. This exists for standardization, so all parameters are read-only. A humanoid skeleton profile contains 54 bones divided in 4 groups: [code]"Body"[/code], [code]"Face"[/code], [code]"LeftHand"[/code], and [code]"RightHand"[/code]. It is structured as follows: [codeblock] Root └─ Hips ├─ LeftUpperLeg │ └─ LeftLowerLeg │ └─ LeftFoot │ └─ LeftToes ├─ RightUpperLeg │ └─ RightLowerLeg │ └─ RightFoot │ └─ RightToes └─ Spine └─ Chest └─ UpperChest ├─ Neck │ └─ Head │ ├─ Jaw │ ├─ LeftEye │ └─ RightEye ├─ LeftShoulder │ └─ LeftUpperArm │ └─ LeftLowerArm │ └─ LeftHand │ ├─ LeftThumbMetacarpal │ │ └─ LeftThumbProximal │ ├─ LeftIndexProximal │ │ └─ LeftIndexIntermediate │ │ └─ LeftIndexDistal │ ├─ LeftMiddleProximal │ │ └─ LeftMiddleIntermediate │ │ └─ LeftMiddleDistal │ ├─ LeftRingProximal │ │ └─ LeftRingIntermediate │ │ └─ LeftRingDistal │ └─ LeftLittleProximal │ └─ LeftLittleIntermediate │ └─ LeftLittleDistal └─ RightShoulder └─ RightUpperArm └─ RightLowerArm └─ RightHand ├─ RightThumbMetacarpal │ └─ RightThumbProximal ├─ RightIndexProximal │ └─ RightIndexIntermediate │ └─ RightIndexDistal ├─ RightMiddleProximal │ └─ RightMiddleIntermediate │ └─ RightMiddleDistal ├─ RightRingProximal │ └─ RightRingIntermediate │ └─ RightRingDistal └─ RightLittleProximal └─ RightLittleIntermediate └─ RightLittleDistal [/codeblock] $DOCS_URL/tutorials/assets_pipeline/retargeting_3d_skeletons.html
