<brief_description>
Base class for a profile of a virtual skeleton used as a target for retargeting.
</brief_description>
<description>
This resource is used in [EditorScenePostImport]. Some parameters are referring to bones in [Skeleton3D], [Skin], [Animation], and some other nodes are rewritten based on the parameters of [SkeletonProfile].
[b]Note:[/b] These parameters need to be set only when creating a custom profile. In [SkeletonProfileHumanoid], they are defined internally as read-only values.

<members>
<member name="bone_size" type="int" setter="set_bone_size" getter="get_bone_size" default="0">
The amount of bones in retargeting section's [BoneMap] editor. For example, [SkeletonProfileHumanoid] has 56 bones.

</member>
<member name="root_bone" type="StringName" setter="set_root_bone" getter="get_root_bone" default="&""">
A bone name that will be used as the root bone in [AnimationTree]. This should be the bone of the parent of hips that exists at the world origin.

<signals>
<signal name="profile_updated">
<description>
This signal is emitted when change the value in profile. This is used to update key name in the [BoneMap] and to redraw the [BoneMap] editor.
[b]Note:[/b] This signal is not connected directly to editor to simplify the reference, instead it is passed on to editor through the [BoneMap].
