# Cinemachine / Set Default Blend
|
|
|
|
Set the default blend on a `CinemachineBrain`. The default blend is used whenever the brain transitions from one live CinemachineCamera to another and no custom blend overrides it.
|
|
|
|
## Inputs
|
|
|
|
- `cameraRef` — optional GameObject hosting the Camera + `CinemachineBrain`. When omitted, `Camera.main` is used.
|
|
- `style` — `CinemachineBlendDefinition.Styles` enum (`Cut`, `EaseInOut`, `EaseIn`, `EaseOut`, `HardIn`, `HardOut`, `Linear`, `Custom`).
|
|
- `time` — blend duration in seconds.
|
|
|
|
## Behavior
|
|
|
|
Resolves the brain (throws if the Camera has none), assigns a new `CinemachineBlendDefinition(style, time)` to `DefaultBlend`, marks the scene dirty, and repaints. Runs on the Unity main thread.
|
|
|
|
## How to Call
|
|
|
|
```bash
|
|
unity-mcp-cli run-tool cinemachine-set-default-blend --input '{
|
|
"style": "string_value",
|
|
"time": 0,
|
|
"cameraRef": "string_value"
|
|
}'
|
|
```
|
|
|
|
> For complex input (multi-line strings, code), save the JSON to a file and use:
|
|
> ```bash
|
|
> unity-mcp-cli run-tool cinemachine-set-default-blend --input-file args.json
|
|
> ```
|
|
>
|
|
> Or pipe via stdin (recommended):
|
|
> ```bash
|
|
> unity-mcp-cli run-tool cinemachine-set-default-blend --input-file - <<'EOF'
|
|
> {"param": "value"}
|
|
> EOF
|
|
> ```
|
|
|
|
|
|
### Troubleshooting
|
|
|
|
If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead.
|
|
Read the /unity-initial-setup skill for detailed installation instructions.

|
|
| `time` | `number` | No | Blend duration in seconds. |
|
|
| `cameraRef` | `any` | No | Optional reference to the GameObject hosting the Camera + CinemachineBrain. If omitted, Camera.main is used. |
