# Shader Integration
**DRM** can be integrated into **Shader Graph**, [**Amplify Shader Editor**](https://assetstore.unity.com/packages/tools/visual-scripting/amplify-shader-editor-68570?aid=1011lvgVb) and hand-written HSLS files:
{% tabs %}
{% tab title=" Shader Graph" %}
Choose required DRM settings inside DRM editor window and then click on the **Shader Graph** button:
DRM node file will be generated and highlighted inside **Project** window. Drag and drop it inside **Shader Graph**:
Node has two inputs:
* **World Position** - This is vertex's absolute world position and by default it is already assigned.
* **Noise** - Available only with **Advanced** DRM nodes and allows adding noise to the calculated mask. Noise strength is controlled from the **DRM Game Object** or **DRM Live Object** scripts.
Output value is a calculated mask - *float* type.
{% hint style="info" %}
Note, in the case of **Additive** DRM node, generated mask value can be in the range of \[-∞, +∞].
With **Normalize** blend mode output value always is in the range of \[0, 1].
{% endhint %}
Inside **Shader Graph** can be used any number of DRM nodes, each one with its own settings.
Each individual DRM node must be updated with its own **DRM Controller** script.
If inside shader several identical DRM nodes are required but each one for different purpose, differentiate them by **ID** property.
{% endtab %}
{% tab title="Amplify Shader Editor" %}
Choose required DRM settings inside DRM editor window and then click on the **Amplify Shader** button:

Each individual DRM node must be updated with its own **DRM Controller** script.

{% endtab %}
{% tab title="Hand-written HLSL" %}
Choose required DRM settings inside DRM editor window and then click on the **cginc** button:
CGINC file will be generated and highlighted inside **Project** window. Path to the file will be copied to the keyboard memory.
```hlsl

{
float4 vertex : SV_POSITION;
float3 worldPos : TEXCOORD0;
};
v2f vert (float4 vertex : POSITION)
{
v2f o;
o.vertex = UnityObjectToClipPos(vertex);
o.worldPos = mul(unity_ObjectToWorld, vertex).xyz;
return o;
}
fixed4 frag (v2f i) : SV_Target
{
float mask = DynamicRadialMasks_HeightField_1_Advanced_Additive_ID1_Local(i.worldPos, 0);
return mask;
}
ENDCG
}
}
}
```
{% hint style="info" %}
Pay attention, DRM ***cginc*** file's name and DRM method's name are identical.
{% endhint %}
DRM methods parameters are:
* Vertex world-space position (*float3* type).
* If using **Advanced** DRM type, then the second parameter is a **Noise** value (*float* type). Noise strength is controlled from the **DRM Game Object** or **DRM Live Object**.
