Replace Color Node

Description

Replaces values in input In equal to input From to the value of input To. Input Range can be used to define a wider range of values around input From to replace. Input Fuzziness can be used to soften the edges around the selection similar to anti-aliasing.

Ports

Name	Direction	Type	Binding	Description
In	Input	Vector 3	None	Input value
From	Input	Vector 3	Color	Color to replace
To	Input	Vector 3	Color	Color to replace with
Range	Input	Float	None	Replace colors within this range from input From

Generated Code Example

The following example code represents one possible outcome of this node.

void Unity_ReplaceColor_float(float3 In, float3 From, float3 To, float Range, float Fuzziness, out float3 Out)
{
    float Distance = distance(From, In);
    Out = lerp(To, In, saturate((Distance - Range) / max(Fuzziness, 1e-5f)));
}
