First off, let me say that after having tried now every other option currently available, I am very, very pleased with SMP4 and RWC. Your cloud formations are simply stunning, and the real weather inputs flawlessly for me so far using FSGRW. My poor PC is absolutely chugging through clouds at 40k sq km, but my frames are fine while in real time, and I only ever notice FPS issues if I try and use time compression. A welcome, and perfectly acceptable tradeoff, in comparison to the absolutely massive suite of issues (and just as many excuses) certain competitors of yours are currently experiencing.
I did have two questions regarding rendering of rain clouds:
-Using the "fast" cloud option. I prefer the look of these clouds, but I notice nothing but white clouds. Am I missing a setting somewhere that will darken rain clouds, or is it just not possible at this current time?
-The only other thing I had noticed was the prevalence of lone towering cumulus clouds in stormy weather. Are there plans to somehow autogenerate a significant amount of clouds around each of these towers? While I understand it is common in some areas to see lone towers like this, it can look funny on the ground (I'm no meteorologist, but I have never seen that IRL), especially when many of them are present.
Sorry for being long-winded. Those are the only two questions I had for now. Keep up the good work.
