Issue with OR Rain texture path

I've been trying to darken the rain texture as it shows up too bright after ENB and OR shaders, but for some reason editing the texture even by changing it to bright red for testing doesn't affect OR's rain in-game at all. I can't find any other texture in the download other than sky/raindrop.dds that seems like it's used for rain, but OR's precipitations seem to ignore this file completely. Is this even the texture being used or am I overlooking it somewhere?

I don't know. You might want to look to the effects/shaders for texture paths. OR ships with all the required resources, so I don't know.
