Shader Water Only

[Axel]

I'm trying to find shaders on the Internet that only change the appearance of water, but unfortunately I only find shaderpacks that give a bunch of idiotic effects and eat up FPS by 2-3 times (my computer is R5 2600 + gtx 1660s + 16gb ram) Are there any such shaders or not? The only thing I found is datLax' OnlyWater 2.0, but the problem is that when the shader is enabled through Optifine, other effects are disabled, such as shadows and fog (and who knows what else). Shadows just disappear....I think because the author forgot to register them in the shader itself, as well as the entire lighting system. Are there any solutions?
