when it rains, the lighting gets darker, but during the day you still see the same cloud shadows overlay as you would see during normal, vanilla sunlight.
it's perturbing my sense of immersion a little. would it be possible to change this shadow layer during the rain? even if it faded out as the rest of the lighting got darker. i just think that having a greater sense of "overcast" skies to go with the rain would really enhance the feeling of the environment that it creates.
love your work!
