# Display Layers
## Display Layers
The Braid Builder's layers are Maya display layers.
{% hint style="info" %}
Unlike Hair Tube/Card Builders, the Braid Builder is one Braid / Curl **ONE** layer.
{% endhint %}
Upon creation, or loading of a new scene, the tool will automatically detect the layers. If for some reason the layers do not refresh, use the  at the top to refresh.
{% hint style="info" %}
If you like to get to the node for the layer, you can do so in the Outliner > Display > uncheck DAG object only
{% endhint %}
### Layer Bar
 **Layer visibility**
* Like Maya's display layers, turn on/off strands in that layer. When multiple layers are selected, all will be toggled.
\
 **Layer Lock**
* Like Maya's display layers, set template/lock on strands in that layer to keep them from being selected. When multiple layers are selected, all will be toggled
**Color Swatch:**
* Color swatch only changes the color of braid/curl's path curve, and the 'top bar' color in the Strand Editor, Flow Creator and Cornrow Creator. Changing the color swatch on a layer wil lnot change the color theme.
* Left-clicking on the color swatch will open up the regular color editor.
* Right-clicking on the color swatch will give you a list of colors for quick access.
* 
\
**Layer Name:**
* **LMB** on the layer name button itself will select all strand in this layer.
* **Ctrl + LMB** on the layer name will allow you to select multiple layers.
* **Shift + LMB** will allow you to batch select layers in their display layer orders. (Only for Maya 2023 +)
* **MMB** to isolate display highlighted layers.
* **RMB** will display more layer functions.

## Layer Options
When right clicking on a layer, you will get some options
### **Create and Add To This Layer**
* With curve selected, create strand and add to the layer.
### **Move Selected To This Layer**

{% hint style="warning" %}

{% endhint %}
