Preparing the 3D Model for Mocap
To prepare your 3D model for mocap, you will need to make sure that it meets certain requirements. These requirements include:
- The model should be in a T-pose.
- The model should have a clean topology.
- The model should have the correct UV maps.
- Use a symmetrical UV layout. This will help to ensure that the mocap data is applied evenly to the model.
- Avoid overlapping UVs. Overlapping UVs can cause problems when the model is textured.
- Use a high enough resolution UV map. A low-resolution UV map can result in blurry textures.
- With the armature selected, enter “Pose Mode” by pressing “Tab.
- Pose the armature to represent the desired vowel sound.
- Go to “Shape Keys” in the Properties Editor and click “New.”
- Enter a name for the shape key (e.g., “A” for the vowel sound “a”).
- Click “Bake Full Body” to create the shape key based on the current pose.
- Use reference images or videos of people pronouncing the vowels to help you create the correct shapes.
- Start with the neutral shape key and then create the vowel shape keys by moving the vertices away from the neutral position.
- Exaggerate the vowel shapes slightly to make them more pronounced.
- Test the vowel shape keys by animating them to make sure that they look correct.
- Make sure that the armature is properly weighted to the mesh.
- Check that the shape keys are assigned to the correct bones.
- Try increasing or decreasing the influence of the shape keys.
- If you are using a modifier stack, try disabling the modifiers one at a time to see if one of them is causing the problem.
- Check for any errors in the console.
- Use as few shape keys as possible.
- Use shape keys that are as specific as possible.
- Limit the influence of shape keys to the areas of the face that they affect.
- Avoid using modifiers that add unnecessary overhead.
Correct UV maps
UV maps are essential for mocap, as they allow the 3D model to be textured. When creating UV maps for mocap, it is important to keep the following tips in mind:
Here is a table that summarizes the key requirements for mocap UV maps:
| Requirement | Description |
|---|---|
| Symmetry | The UV map should be symmetrical. |
| No overlapping | The UV map should not have any overlapping UVs. |
| High resolution | The UV map should be of a high enough resolution to avoid blurry textures. |
Capturing the Vowel Data
To capture the vowel data, you will need to use a microphone and a computer. You can use a USB microphone or a built-in microphone on your computer. Once you have your microphone set up, you can start recording your vowel sounds.
To record a vowel sound, start by saying the vowel sound clearly and slowly into the microphone. Hold the vowel sound for a few seconds, then stop speaking. You should record each vowel sound several times to ensure you have a good recording.
Once you have recorded your vowel sounds, you can import them into Blender. To do this, go to the “File” menu and select “Import” > “Sound”. Select the vowel sound file you want to import and click “Import Sound”.
Once the vowel sound file is imported, you can create a new shape key for it. To do this, go to the “Object” menu and select “Shape Keys” > “New Shape Key”. In the “New Shape Key” dialog box, enter a name for the shape key and click “OK”.
The shape key will be created and assigned to the selected object. You can now use the shape key to animate the object’s shape. To do this, go to the “Animation” menu and select “Shape Keys” > “Create Shape Key Animation”.
In the “Create Shape Key Animation” dialog box, select the shape key you want to animate and click “OK”. The shape key will be added to the timeline and you can now animate it.
To animate the shape key, select the keyframe at the beginning of the animation and set the value to 0. Then, select the keyframe at the end of the animation and set the value to 1. This will cause the object’s shape to change from its original shape to the shape defined by the shape key.
You can now play the animation to see the object’s shape change. You can also adjust the values of the keyframes to change the speed and duration of the animation.
Face Tracking Setup
| Make sure your webcam is properly connected and configured in Blender. |
| Go to the “Object” menu and select “Create” > “Camera”. |
| In the “Camera” properties panel, select the “Tracking” tab. |
| In the “Tracking” tab, select the “Device” drop-down menu and select your webcam. |
| Click the “Start Tracking” button. |
Blender will now start tracking your face. You will see a green box around your face in the 3D Viewport. You can adjust the size and position of the green box by dragging the handles on the box.
Once you have adjusted the green box, you can start recording your facial movements. To do this, click the “Record” button in the “Tracking” tab. Blender will now start recording your facial movements. You should make a variety of facial expressions to capture all of the different movements that your face can make.
Once you have finished recording your facial movements, you can stop the recording by clicking the “Stop” button in the “Tracking” tab. Blender will now create a shape key for each of the facial movements that you recorded.
You can now use the shape keys to animate your character’s face. To do this, select the shape key you want to animate and click the “Animate” button in the “Shape Keys” panel. Blender will now create a new animation track for the shape key. You can now animate the shape key by adjusting the values of the keyframes in the animation track.
Importing the Mocap Data into Blender
1. File Preparation
Ensure that your mocap data is in a format compatible with Blender, such as FBX or BVH. If necessary, use a third-party conversion tool.
2. Blender Import
Open Blender and go to “File” > “Import” > “FBX” (or BVH). Select the mocap file to import into your scene.
3. Scale and Positioning
Adjust the scale and position of the imported mocap data to match the size and location of your 3D model. Use the “Transform” tools in the 3D viewport for this purpose.
4. Naming and Organization
Rename the imported armature and its bones to align with the names of your face rig. Organize the armature and its bones into logical groups or layers within the Outliner.
5. Creating Shape Keys for Vowels
To create shape keys for each vowel, follow these steps:
| Key | Shape |
|---|---|
| A | Mouth open, rounded |
| E | Mouth open, wide |
| I | Mouth open, narrow |
| O | Mouth open, puckered |
| U | Mouth open, rounded with puckered lips |
Creating the Face Bones
Once the face mesh is created, it’s time to begin adding the bones that will control the movement of the face. This process is called rigging, and it involves creating a hierarchical structure of bones that are connected to the mesh vertices.
Creating the Root Bone
The first step is to create the root bone, which will be the parent of all the other bones in the face. To do this, select the “Add” menu in the 3D Viewport and choose “Armature” > “Single Bone”.
Creating the Jaw Bone
The next step is to create the jaw bone. This bone will rotate forward and backward, moving the jaw. To create the jaw bone, select the “Add” menu again and choose “Armature” > “Bone”. Position the bone between the jaw and the skull, and then rotate it so that it is pointing forward.
Creating the Lips Bones
The lips are controlled by a set of bones that connect the upper and lower lips. To create these bones, select the “Add” menu and choose “Armature” > “Bone”. Repeat this process for each lip, positioning the bones in the center of each lip.
Creating the Eyebrow Bones
The eyebrows are controlled by a set of bones that connect the inner and outer corners of each eyebrow. To create these bones, select the “Add” menu and choose “Armature” > “Bone”. Repeat this process for each eyebrow, positioning the bones near the center of each eyebrow.
Creating the Eyelid Bones
The eyelids are controlled by a set of bones that connect the upper and lower eyelids. To create these bones, select the “Add” menu and choose “Armature” > “Bone”. Repeat this process for each eyelid, positioning the bones near the center of each eyelid.
Creating the Masseter Bones
The masseter muscles are located on either side of the jaw, and they are responsible for closing the mouth. To create these bones, select the “Add” menu and choose “Armature” > “Bone”. Repeat this process for each masseter muscle, positioning the bones near the center of each muscle.
| Bone Name | Description |
|---|---|
| Root Bone | Parent of all other bones in the face |
| Jaw Bone | Rotates forward and backward to move the jaw |
| Lips Bones | Connect the upper and lower lips |
| Eyebrow Bones | Connect the inner and outer corners of the eyebrows |
| Eyelid Bones | Connect the upper and lower eyelids |
| Masseter Bones | Located on either side of the jaw, used to close the mouth |
Weight Painting the Face Bones
7. Weight Painting the Lips
Weight painting the lips requires precision and attention to detail to capture their complex movements accurately.
Begin by selecting the lips’ vertices in Edit Mode. Create a new vertex group named “Lips” and assign it to the lips’ vertices. Switch to Weight Paint Mode and adjust the weight values by painting the lips with a stronger weight near the center and a weaker weight towards the edges.
To further improve accuracy, consider creating separate vertex groups for the upper and lower lips. Additionally, create vertex groups for the corners of the lips to control their specific movements.
Below is a table summarizing the vertex groups and their associated bones:
| Vertex Group | Associated Bones |
|---|---|
| Lips | Upper Jaw, Lower Jaw, Lips |
| Upper Lip | Upper Jaw, Lips |
| Lower Lip | Lower Jaw, Lips |
| Lip Corners | Upper Jaw, Lower Jaw |
Creating Shape Keys for Vowels
Once the bones have been created for the face rig, the next step is to create shape keys for the vowels. Shape keys are used to define the different shapes that the face can make, and they are essential for creating realistic facial animations.
To create a shape key for a vowel, first select the armature object in the 3D Viewport. Then, go to the Shape Keys menu in the Properties panel and click on the “New” button. A new shape key will be created, and you can name it according to the vowel that it represents.
Once the shape key has been created, you can begin to edit it. To do this, select the mesh object in the 3D Viewport and go to the Edit Mode. Then, select the vertices that you want to move for the vowel shape. You can use the Transform Tools to move the vertices into the desired position.
Once you have moved the vertices into the desired position, you can click on the “Set Key” button in the Shape Keys menu in the Properties panel. This will save the current position of the vertices as the shape key.
You can repeat this process for each of the vowels. Once you have created shape keys for all of the vowels, you can begin to animate the face rig. To do this, go to the Animation Editor and create a new action. Then, select the armature object and go to the Dopesheet Editor. You can then use the Shape Key Editor to animate the shape keys for the vowels.
Tips for Creating Vowel Shape Keys
Here are a few tips for creating vowel shape keys:
Animating the Vowel Expressions
To animate the vowel expressions, you will need to create keyframes for each of the blend shapes. You can do this by selecting the blend shape in the Shape Keys panel and then clicking the “Insert Keyframe” button (I). For each vowel, you should create three keyframes: one for the start of the animation, one for the peak of the animation, and one for the end of the animation.
The start keyframe should have the blend shape at 0%. The peak keyframe should have the blend shape at 100%. The end keyframe should have the blend shape at 0%. You can adjust the timing of the keyframes to control how quickly the animation plays.
Here is a table summarizing the keyframes for each vowel:
| Vowel | Start Keyframe | Peak Keyframe | End Keyframe |
|---|---|---|---|
| a | 0% | 100% | 0% |
| e | 0% | 100% | 0% |
| i | 0% | 100% | 0% |
| o | 0% | 100% | 0% |
| u | 0% | 100% | 0% |
