Description

Bones are non-rendered objects that drive the movement of one or more parts for the purposes of animation, or creating clothing and characters. Bones are part of a Model or MeshPart object's skeletal rig that you typically access and animate through the Animation Editor.

Rigs are created during the modeling process in third-party software such as Blender or Maya. After importing the rigged model into Studio, you can add the model directly to your experience, or save and share the model as an asset. See Rigging for more details on creating and using rigged models.

Note that you can parent Bones under other Bones and parts. When parenting a bone to another bone, the child bone's world position will be relative to the parent bone's position, and the hierarchy of parented Bone objects can change the behavior of affected parts during posing or animation.

Relationship with Motor6D

To support animations with older rigs using joints, such as Motor6D, you can use the Bone.Transform property in the same way as Motor6D.Transform. Roblox uses the offset of the bones from the default pose to drive an animation, and bones are not replicated or serialized.

Bone.CFrame

Bones inherit the CFrame property of Attachments which Roblox uses as the bone's reference position. The inherited WorldCFrame and other world properties return the initial un-transformed position.
