## Usage

- **For camera animation**, just right click on VMD file and select `MMD/Create Camera Anim`<br>
Based on the structure of anim, you need to create two empty objects in the scene as follows,
and rename the middle object to `Distance.`

### For camera animation
just right click on VMD file and select `MMD/Create Camera Anim`
Based on the structure of anim, you need to make the camera conform to this structure<br>
![](pic/struct.png)
#### Method1
1. Create two empty objects in the scene and set their parent
2. Add `Animator component` to the top-level object (yes, not to Camera)
3. Rename the middle object to `Distance`
4. Rotate "Distance" 180 degrees in the Y axis
#### Method 2
Use the tool script to create it with just one click <br>
But it will create an additional Camera, and you may need to adjust the `GenerateMMDCamera` method in `MMD6UnityTool/Editor/AnimationHelpers.cs` (after line 115) for you own needs <br>
![](pic/camera.png)

When you use camera animation via Timeline, remember uncheck `Remove Start Offset` in Clip properties<br>
![](pic/offset.png)

- **For morph animation**, you need to select the object in the scene that contains the blendshapes of the face under the
model
### For morph animation
you need to select the object in the scene that contains the blendshapes of the face under the model
(If it is generated by MMD4Mecanim, it is usually `your model/U_Char/U_Char_1`)<br>
and select the VMD with morph (ie: multi selection)<br>
![](pic/morph.png) <br>
Then right click and select `MMD/Create Morph Anim`

- When you use camera animation via Timeline, please uncheck `Remove Start Offset` in Clip properties<br>
