Adjusts the strength of the normal map defined by input In by the amount of input Strength. A Strength value of 1 will return the input unaltered. A Strength value of 0 will return a blank (flat) tangent-space normal: vector (0, 0, 1). When encoded as a texture color in the 0–1 range, this corresponds to (0.5, 0.5, 1.0) or 128, 128, 255 in 8-bit.
| 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 |
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)));
}
