基础用法¶
Basic Rig Generation¶
Add a meta-rig structure from the menu.
Edit the bone positions to match the character geometry.
In the armature properties click on the Generate button to generate the rig.
Add a Predefined Meta-Rig¶

Rigify stores all the information required to generate complex rig controls and mechanism in more simple armatures called "meta-rigs".
The precompiled meta-rigs can be found in the Add menu. Currently available meta-rig types are:
Basic Human
Basic Quadruped
Human
猫
狼
马
鲨鱼
编辑骨骼位置¶
To correctly match your character, meta-rig bones must be moved to correct positions. This can be achieved in two different ways: Pose Mode or Edit Mode.
Note
Rigify assumes that 1 unit corresponds to 1 meter. So a human is about 2 units tall. If your character is in a different scale and you are more familiar with modeling rather than rigging, it is suggested to scale it to Rigify dimensions before positioning the meta-rig bones. f you want to scale the character's geometry, we suggest you to first scale up the character in Object Mode, then apply the geometry scale with the Apply Scale tool.
Rigify Human Alignment Tips¶
Limbs: Keep the legs as straight as possible in the front view (Rigify human works better in predictable cases). Give the knee and the elbow a slight bend angle (Rigify needs to know where your knee/elbow is pointing).
Torso: Keep the spine as straight as possible in the front view (Rigify human works better in predictable cases). The last bone of the spine is the head. By default the next two bones (top to bottom) are considered the neck bones. It is suggested to keep the neck bones as aligned as possible while editing.
Face: Positioning face bones can be tricky if you are not an expert in bone editing and they are almost useless if you plan to make facial animation through shape keys. Consider removing face features from your character if they aren't really needed. If you don't need the face all the face bones can be deleted. All the face bones are on the first armature layer by default. You can select them by displaying only bone layer 1, selecting all of its content and then deleting the bones in Edit Mode to correctly remove the face.
If you want to scale all the face bones at once, consider scaling the face master bone in Pose Mode (see Pose Mode matching method). The face master bone is placed in the same position of the head bone. To select it easily, hide all other bone layers.
For more tips, see the Positioning Guide.
Pose Mode Matching (Basic)¶
Enter the meta-rig Pose Mode. Rotate, scale, and translate the bones in the correct position. When bones are in correct positions (always staying in Pose Mode) use .
Note
Connected bones cannot be translated in Pose Mode. You can scale the parent bones to match the general length and then refine child bones scale. For more detailed information on armature modes please refer to the armatures section.
Edit Mode Matching (Advanced)¶
Some basic armature display setup is suggested before entering bone Edit Mode.
With the meta-rig selected, go in the Properties and click on the Object tab. Scroll down to the display panel and enable X-ray and under Maximum Draw Type selector select Wire. This way the bones will always be drawn in wireframe on top of your geometry.
Then, always in the Properties click on the Armatures tab and under display check the Axis checkbox. This way you the bones rotation axes will be displayed during the edit process.
For more detailed information on armature display modes please refer to the Display panel page.
Generating the Rig¶
With the bones in the correct positions, jump back in Object Mode, go to the Armature tab, scroll down to the bottom and click on the Generate button to finalize the rig creation. The generation process will take from few seconds to one minute depending on rig complexity and hardware specifications of your machine. If the generated rig needs tweaking you can modify the meta-rig accordingly and then click again on the generate button. If the rig already exists, Rigify will simply overwrite it retaining all your modifiers and constraints and -- where possible -- all the previously generated features.
If you need to generate more than one rig in the scene or update a specific one (when there are more than one in the same file) follow the instructions in the Advanced Rig Generation section.
Tip
Rig Updating
To make the rig overwriting work as expected, you need to have both the rig and the meta-rig visible before generating again.
Warning
As with all Python add-ons, Blender interface cannot be updated until the Python script execution is over. Wait until the rig appears to see the results.
Binding the Geometry to the Rig¶
To bind the geometry to the rig you can use your preferred tools. Just few things you have to know:
All the deforming bones are on the armature layer 30.
Eyes and Teeth bones are not deforming. You are supposed to bind the eyes and teeth geometry through Child Of constraints.
Usually armature deform with automatic weights do a really good job out of the box if you correctly place your bones (and there's enough topology to work with!).
For more detailed information on armature layers, Armature modifier and weight painting refer to the Blender manual.
Advanced Rig Generation¶
Advanced Options Features¶
When Advanced Options are enabled, user will be able to:
Generate more than one rig per scene.
Generate a rig with a specific name.
Update/Overwrite a specific rig.
Advanced Options Activation¶
Advanced Rig Generation Options are locked by default. Click on the Advanced Options button to enable. With Advanced Options enabled the panel will be updated displaying two main modes:
覆盖
新建
By default overwrite is selected. At this stage if you don't touch anything in the UI the generate function will be invoked as is, meaning in fact that generating the rig now will create a new rig from the meta-rig if none is present in the scene, or overwrite the default one if you have already generated a rig from a meta-rig. For further information about the Rigify generate function look at basic usage section.
New Rig Mode¶
The New rig mode will let the user generate a new rig from the meta-rig regardless of
an already generated rig is present in the scene.
A specific name for the rig can be set by the user through the specific Rig Name text field.
If no name is set, Rigify will generate an armature object named "rig" and a Python script named rig_ui.py.
Note
Keep in mind that along with the rig, Rigify generates also a rig_ui Python script
which controls the UI in the 3D Viewport. This Python script will be named accordingly with
the specified rig name.
Overwrite Rig Mode¶
The Overwrite rig mode will let the user specify a target rig to be overwritten.
If none is set Rigify will search and eventually overwrite an armature object named "rig" and
a Python script named rig_ui.py.
Library Linking¶
When linking a rig into another file, you generally want to create a group that includes the generated rig, the character mesh, and the "WGT-" objects. You do not need to include the meta-rig. You then link in the group, make a group instance, and make the rig proxy.
You also need to separately link in the rig_ui.py text data-block.
Otherwise the rig UI will not appear in the Sidebar.
