 UIDetect はとても便利なシェーダーですが、適用できるマスクが3つまでと少ない。そこで、もっと適用できるマスクを増やして使えるように改造をしてみました。10個以上使えるようにすると不具合が起きてしまい、それを修正する事ができなかったので、適用できるマスクは9個までです。改造するのは
UIDetect.fxの方で、変更内容は以下の通り。
38行目あたりにある下記の個所を
#if (UIDetect_USE_RGB_MASK == 1)
    texture texUIDetectMask <source="UIDetectMaskRGB.png";>
    { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; Format=RGBA8; };
    sampler UIDetectMask { Texture = texUIDetectMask; };
#endif
以下の様に変更する。
#if (UIDetect_USE_RGB_MASK == 1)
    texture texUIDetectMask_1 <source="UIDetectMaskRGB.png";>
    { Width = BUFFER_WIDTH; Height = BUFFER_HEIGHT; Format=RGBA8; };

 9個では足りなく、もっと適用できるマスクが欲しかったりマスクを重ねたい場合は、
UIDetect.fx, UIDetect.fxhを複製して使用します。複製した方の
UIDetect.fxの
#include "ReShadeUI.fxh"や
texColorOrigや
texUIDetectが元の
UIDetect.fxと被らないように適当に名前を変更してください。同様のシェーダーを重複してエフェクトをかけるのは無駄に負荷をかける気もしますが、このシェーダーは大した影響もなさそうなので、たぶん大丈夫、でしょう。
