How to make a shader lighting aware

Question

I followed a tutorial on adding water in Godot 4, which is a fragment/vertex shader - it works but shown on the picture is an example of how 'evenly lit' it is everywhere.

At the end of the tunnel it is dark (lighting wise) - but the water is still bright. How can I make the shader 'aware' of lighting?

Any tips to push me into the right direction?

I changed the shader mode to Mul and now it picks up on the lighting 😉 no idea how it works but sure 😃

There is a light function, similar to the vertex and fragment. You can write it yourself, but it's kind of involved.

It might be a better idea to customize the standard material instead. You can use the drop down arrow to convert a standard material to a shader material, then add your code.
