## Generated Code Example
|
|
|
|
The following example code represents one possible outcome of this node per **Mode**.
|
|
|
|
**Default**
|
|
|
|
```
|
|
void Unity_NormalBlend_float(float3 A, float3 B, out float3 Out)
|
|
{
|
|
Out = normalize(float3(A.rg + B.rg, A.b * B.b));
|
|
}
|
|
```
|
|
|
|
**Reoriented**
|
|
|
|
```
|
|
void Unity_NormalBlend_Reoriented_float(float3 A, float3 B, out float3 Out)
|
|
{
|
|
float3 t = A.xyz + float3(0.0, 0.0, 1.0);
|
|
float3 u = B.xyz * float3(-1.0, -1.0, 1.0);
|
|
Out = (t / t.z) * dot(t, u) - u;
|
|
}
|
|
```
