Hey!

I have a shader that generates a very nice "fog" effect. I also have a number of 2D lights in my scene. I would like to be able to, in the fog shader, set a fragment alpha based on how close it is to a light source. The closer the source, the more transparent it becomes... simulating the light burning the fog away.

I noticed I can use light(){} in the fragment shader, but, as the name implies, it only effects the lighting of the fog. I cannot seem to affect the alpha of the fragment with the light(){} function. Conversely, there doesn't seem to be a way for me to obtain the light information from within the fragment(){} functions.

Again... this is for 2D, not 3D.

Is there something I'm missing, or is this just not possible with Godot at present?
