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	Vector 1	None	Replace colors within this range from input From
Fuzziness	Input	Vector 1	None	Soften edges around selection
Out	Output	Vector 3	None	Output value

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)));
}
