# Using Noise Profiles
|
||
|
|
|
||
|
|
Cinemachine uses a **[Noise Profile](CinemachineNoiseProfiles.md)** Asset to generate Basic Multi-Channel Perlin noise for Cinemachine Virtual Cameras. You can use the same Asset to create a procedural raw signal for Impulse.
|
||
|
|
|
||
|
|
The **Noise Profile** Asset allows you to add noise in up to six dimensions: three rotational axes and three positional axes. Typical camera noise profiles use only rotational noise, but for Impulse you often want positional noise as well.
|
||
|
|
|
||
|
|
Cinemachine ships with several **Noise Profile** presets, which you can use as they are, or clone and customize. **6D Shake** is a good all-around profile that you can use for a wide variety of situations.
|
||
|
|
|
||
|
|
## Connecting a noise profile to an Impulse Source
|
||
|
|
|
||
|
|
To connect a noise profile Asset to an Impulse Source or a Collision Impulse Source, do one of the following:
|
||
|
|
|
||
|
|
- In the Impulse Source Inspector, click the gear icon next to the **Raw Signal** field and choose a preset from the **Presets** section of the menu.
|
||
|
|
|
||
|
|
- In the Project view, locate the noise profile you want to connect and drag it onto the **Raw Signal** field in the Impulse Source Inspector.
|
||
|
|
|
||
|
|
## Creating a new noise profile
|
||
|
|
|
||
|
|
You can create your own noise profiles from scratch in the Noise Profile Inspector; however, you might find it easier to clone an existing preset and edit it.
|
||
|
|
|
||
|
|
To create a new noise profile Asset:
|
||
|
|
|
||
|
|
1. In the Impulse Source Inspector, click the gear icon next to the **Raw Signal** field and choose **New Noise Settings**.
|
||
|
|
|
||
|
|
2. When prompted, give the new Asset a name and choose a location to save it to.
|
||
|
|
|
||
|
|
3. Locate the new Asset in the Project view and select it to open the Noise Profile Inspector.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
The Inspector displays a compound waveform for rotational noise and positional noise. You can expand any rotational or positional axis to view and edit its waveforms individually.
