Rig tab

The settings on the Rig tab define how Unity maps the deformers to the Mesh in the imported Model so that you can animate it. For Humanoid characters, this means assigning or creating an Avatar. For non-Humanoid (Generic) characters, this means identifying a Root bone in the skeleton.

By default, when you select a Model in the Project view, Unity determines which Animation Type best matches the selected Model and displays it in the Rig tab. If Unity has never imported the file, the Animation Type is set to None:

No rig mapping
No rig mapping
Propiedad: Función:
Animation Type Specfiy the type of animation.
None Ninguna animación presente
Legacy Use the Legacy Animation System. Import and use animations as with Unity version 3.x and earlier.
Generic Use the Generic Animation System if your rig is non-humanoid (quadruped or any entity to be animated). Unity picks a root node but you can identify another bone to use as the Root node instead.
Humanoid Use the Humanoid Animation System if your rig is humanoid (it has two legs, two arms and a head). Unity usually detects the skeleton and maps it to the Avatar correctly. In some cases, you may need to set a change the Avatar Definition and Configure the mapping manually.

Generic animation types

Your rig is non-humanoid (quadruped or any entity to be animated)
Your rig is non-humanoid (quadruped or any entity to be animated)

Generic Animations do not use Avatars like Humanoid animations do. Since the skeleton can be arbitrary, you must specify which bone is the Root node. The Root node allows Unity to establish consistency between Animation clips for a generic model, and blend properly between Animations that have not been authored “in place” (that is, where the whole model moves its world position while animating).

Specifying the root node helps Unity determine between movement of the bones relative to each other, and motion of the Root node in the world (controlled from OnAnimatorMove).

Propiedad: Función:
Avatar Definition Choose where to get the Avatar definition.
Create from this model Create an Avatar based on this model
Copy from Other Avatar Point to an Avatar set up on another model.
Root node Select the bone to use as a root node for this Avatar.

This setting is only available if you set the Avatar Definition to Create From This Model.
Source Copy another Avatar with an identical rig to import its animation clips.

This setting is only available if you set the Avatar Definition to Copy from Other Avatar.
Skin Weights Set the maximum number of bones that can influence a single vertex.

See the Importing skinned Meshes documentation for more information.
Standard (4 Bones) Use a maximum influence of four bones. This is the default, and is recommended for performance.
Custom Set your own maximum number of bones.

When you select this option, the Max Bones/Vertex and Max Bone Weight properties appear.
Max Bones/Vertex Set the maximum number of bones per vertex to influence a given vertex. You can set between 1 and 32 bones per vertex, but the higher the number of bones you use to influence a vertex, the greater the performance cost.

This setting is only available you set the Skin Weights property to Custom.
Max Bone Weight Set the bottom threshold for considering bone weights. The weighting calculation ignores anything smaller than this value, and Unity scales up the bone weights higher than this value to a total of 1.0.

This setting is only available if the Skin Weights property is set to Custom.
Optimize Game Object Remove and store the GameObject transform hierarchy of the imported character in the Avatar and Animator component. If enabled, the SkinnedMeshRenderers of the character use the Unity animation system’s internal skeleton, which improves the performance of the animated characters.

Only available if the Avatar Definition is set to Create From This Model.

Enable this option for the final product.

Note: In optimized mode, skinned mesh matrix extraction is also multi-threaded.

Humanoid animation types

Your rig is humanoid (it has two legs, two arms and a head)
Your rig is humanoid (it has two legs, two arms and a head)

With rare exceptions, humanoid models have the same basic structure. This structure represents the major articulated parts of the body: the head and limbs. The first step to using Unity’s Humanoid animation features is to set up and configure an Avatar. Unity uses the Avatar to map the simplified humanoid bone structure to the actual bones present in the Model’s skeleton.

Propiedad: Función:
Avatar Definition Choose where to get the Avatar definition.
Create from this model Create an Avatar based on this model
Copy from Other Avatar Point to an Avatar set up on another model.
Source Copy another Avatar with an identical rig to import its animation clips.

Only available if the Avatar Definition is set to Copy from Other Avatar.
Configure… Open the Avatar configuration.

Only available if the Avatar Definition is set to Create From This Model.
Skin Weights This property is identical for both Humanoid and Generic Models. See the documentation on Skin Weights above for information about it.
Optimize Game Object Remove and store the GameObject transform hierarchy of the imported character in the Avatar and Animator component. If enabled, the SkinnedMeshRenderers of the character use the Unity animation system’s internal skeleton, which improves the performance of the animated characters.

Only available if the Avatar Definition is set to Create From This Model.

Enable this option for the final product.
