# Variables
Variables will show up in Material Editor. They're defined like this.
```
float3 g_vColorTint < UiType( Color ); Default3( 1.0, 1.0, 1.0 ); UiGroup( "Color,10/20" ); >;
```
## UiType
Describes how the variable should be represented in the editor.
|Name|Description|
|-----|----------|
| VectorText | Text boxes and sliders (this is the default) |
| Slider | A slider type. Usually combined with a Range setting. |
| Color | A Color picker, works on float3 or float4. |
| Texture | A texture picker |
| CheckBox | On or off, generally used on bool |
## Default
The Default lets you specify the default value for the variable. If you're filling a `float2`, it should be `Default2`, if you're filling a `float4` it should be `Default4` etc.
## UiGroup
The UiGroup is used to sort the variable into a group, subgroup and define its order. So for example, given this..
```
float4 BorderColorL < UiType( Color ); Default4( 0.0, 0.0, 0.0, 1.0 ); UiGroup( "Border,10/Colors,10/1" ); >;
float4 BorderColorT < UiType( Color ); Default4( 0.0, 0.0, 0.0, 1.0 ); UiGroup( "Border,10/Colors,10/2" ); >;
float4 BorderColorR < UiType( Color ); Default4( 0.0, 0.0, 0.0, 1.0 ); UiGroup( "Border,10/Colors,10/3" ); >;
float4 BorderColorB < UiType( Color ); Default4( 0.0, 0.0, 0.0, 1.0 ); UiGroup( "Border,10/Colors,10/4" ); >;
```
You end up with this
