When Unity imports Model filesA file containing a 3D data, which may include definitions for meshes, bones, animation, materials and textures. More info
See in Glossary that contain Humanoid Rigs and Animation, it needs to reconcile the bone structure of the Model to its Animation. It does this by mapping each bone in the file to a Humanoid Avatar so that it can play the Animation properly. For this reason, it is important to carefully prepare your Model file before importing into Unity.
From the Rig tab of the Inspector window, set the Animation Type to Humanoid. By default, the Avatar Definition property is set to Create From This Model. If you keep this option, Unity attempts to map the set of bones defined in the file to a Humanoid Avatar.
Note: In some cases, you can change this option to Copy From Other Avatar to use an Avatar you already defined for another Model file. For example, if you create a MeshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info
See in Glossary (skin) in your 3D modeling application with several distinct animations, you can export the Mesh to one FBX file, and each animation to its own FBX file. When you import these files into Unity, you only need to create a single Avatar for the first file you import (usually the Mesh). As long as all the files use the same bone structure, you can re-use that Avatar for the rest of the files (for example, all the animations).
If you enable this option, you must specify which Avatar you want to use by setting the Source property.
Click the Apply button. Unity tries to match up the existing bone structure to the Avatar bone structure. In many cases, it can do this automatically by analyzing the connections between bones in the rig.
If the match succeeds, a check mark appears next to the Configure menu. Unity also adds an Avatar sub-asset to the Model Asset, which you can find in the Project viewA view that shows the contents of your Assets folder (Project tab) More info
See in Glossary.
A successful match simply means that Unity was able to match all of the required bones. However, for better results, you also need to match the optional bones and set the model in a proper T-poseThe pose in which the character has their arms straight out to the sides, forming a “T”. The required pose for the character to be in, in order to make an Avatar.
See in Glossary.
If Unity can’t create the Avatar, a cross appears next to the Configure button, and no Avatar sub-asset appears in the Project view.
Since the Avatar is such an important aspect of the animation system, it is important to configure it properly for your ModelA 3D model representation of an object, such as a character, a building, or a piece of furniture. More info
See in Glossary.
For this reason, whether or not the automatic Avatar creation succeeds, you should always check that your Avatar is valid and properly set up.
If Unity failed to create the Avatar for your model, you must click the Configure … button on the RigA skeletal hierarchy of joints for a mesh. More info
See in Glossary tab to open the Avatar window and fix your Avatar.
If the match was successful, you can either click the Configure … button on the Rig tab or open the window from the Project view:
If you haven’t already saved the Avatar, a message appears asking you to save your scene:
The reason for this is that in Configure mode, the Scene viewAn interactive view into the world you are creating. You use the Scene View to select and position scenery, characters, cameras, lights, and all other types of Game Object. More info
See in Glossary is used to display bone, muscle and animation information for the selected model alone, without displaying the rest of the scene.
Once you have saved the scene, the Avatar window appears in the Inspector displaying any bone mapping.
Make sure the bone mapping is correct and that you map any optional bones that Unity did not assign.
Your skeleton needs to have at least the required bones in place for Unity to produce a valid match. In order to improve your chances for finding a match to the Avatar, name your bones in a way that reflects the body parts they represent. For example, “LeftArm” and “RightForearm” make it clear what these bones control.
If the model does not yield a valid match, you can use a similar process to the one that Unity uses internally:
If automapping fails completely or partially, you can manually assign bones by either dragging them from the SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary view or from the Hierarchy view. If Unity thinks a bone fits, it appears in green in the Avatar Mapping tab; otherwise it appears in red.
The T-pose is the default pose required by Unity animation and is the recommended pose to model in your 3D modeling application. However, if you did not use the T-pose to model your character and the animation does not work as expected, you can choose the :
If the bone assignment is correct, but the character is not in the correct pose, you will see the message “Character not in T-Pose”. You can try to fix that by choosing Enforce T-Pose from the Pose menu. If the pose is still not correct, you can manually rotate the remaining bones into a T-pose.
Masking allows you to discard some of the animation data within a clip, allowing the clip to animate only parts of the object or character rather than the entire thing. For example, you may have a standard walking animation that includes both arm and leg motion, but if a character is carrying a large object with both hands then you wouldn’t want their arms to swing to the side as they walk. However, you could still use the standard walking animation while carrying the object by using a mask to only play the upper body portion of the carrying animation over the top of the walking animation.
You can apply masking to animation clips either during import time, or at runtime. Masking during import time is preferable, because it allows the discarded animation data to be omitted from your build, making the files smaller and therefore using less memory. It also makes for faster processing because there is less animation data to be blended at runtime. In some cases, import masking may not be suitable for your purposes. In that case, you can apply a mask at runtime by creating an Avatar MaskA specification for which body parts to include or exclude for an animation rig. Used in Animation Layers and in the importer. More info
See in Glossary Asset, and using it in the layer settings of your Animator ControllerControls animation through Animation Layers with Animation State Machines and Animation Blend Trees, controlled by Animation Parameters. The same Animator Controller can be referenced by multiple models with Animator components. More info
See in Glossary.
To create an empty Avatar Mask Asset, you can either:
The new Asset appears in the Project view:
You can now add portions of the body to the mask and then add the mask to either an Animation LayerAn Animation Layer contains an Animation State Machine that controls animations of a model or part of it. An example of this is if you have a full-body layer for walking or jumping and a higher layer for upper-body motions such as throwing an object or shooting. The higher layers take precedence for the body parts they control. More info
See in Glossary or add a reference to it under the MaskCan refer to a Sprite Mask, a UI Mask, or a Layer Mask More info
