Color Mask ノード
説明
入力 Mask Color と等しい入力 In の値からマスクを作成します。入力 Range を使用すると、マスクの作成に際して、より広い範囲 (入力 Mask Color からの範囲) の値を定義できます。範囲内の色は 1 を返し、それ以外の場合は 0 を返します。入力 Fuzziness を使用すると、アンチエイリアスのように、選択範囲の境界をなじませることができます。

生成されるコードの例
以下のサンプルコードは、このノードの出力の一例を示したものです。
void Unity_ColorMask_float(float3 In, float3 MaskColor, float Range, float Fuzziness, out float4 Out)
{
float Distance = distance(MaskColor, In);
Out = saturate(1 - (Distance - Range) / max(Fuzziness, 1e-5));
}
