+# Normal Strength Node

+
+## Ports
+
+| Name        | Direction           | Type  | Binding | Description |
+|:------------ |:-------------|:-----|:---|:---|
+| In      | Input | Vector 3 | None | Input value |
+| Strength      | Input | Float    | None | Strength value |
+| Out | Output      |    Vector 3 | None | Output value |
+
+## Generated Code Example
+
+The following example code represents one possible outcome of this node.
+
+```
+void Unity_NormalStrength_float(float3 In, float Strength, out float3 Out)
+{
+    Out = {precision}3(In.rg * Strength, lerp(1, In.b, saturate(Strength)));
+}
+```
