The distortion effect is already available in the NovelMix pack (via the shader) I linked PatternMix because it's the only one with a tutorial on how to use it.
You are truly amazing. I had expected the example shown here—which is beautiful, by the way—to be the one available for study so I could learn how to use the effects in my game. However, I ended up buying your PatternMix asset instead, and that is going to help me a great deal. In any case, thank you very much for the reply and for making PatternMix available; even though it isn't the specific example from this page, it is greatly appreciated. Thanks again.
