While I'm reasonably happy with skymaxx pro4 clouds through the day I think they look terrible and totally unrealistic at dusk (a favourite time to fly I'm sure with a lot of people). I have been looking at clouds to close to 50 years now both on the ground and from the air and I can't recall ever seeing black clouds (apart from intense thunderstorm activity which this is not), grey yes - black no.
In fact I was lying in bed last night watching them with great interest as they went from white to a bit of colour and then grey with the setting sun, never black like depicted in xplane/skymaxx pro4. In the image posted the setting sun is directly behind the aircraft. I'm happy with the cloud textures leading up to this point and even 2 of the small clouds in the middle have the right shade of grey but all the rest.....
Am I doing something wrong or is this what everyone else sees?
