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.

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)));
}
