Normal Strength Node

Description

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.

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)));
}
