Glad to hear that most people are enjoying the mod. Although Stiebler is the "brains" of this operation (he is responsible for all of the coding and documentation, both of us are responsible for testing and the suggested new settings), I will attempt to answer a few questions.
The RWF is primarily designed to reduce the unending "sticky storms" that plague most long patrols, so it mostly reduces heavy storms and does not create more variable weather. Personally, I would also prefer more variable weather in RWF, but the weather algorithm in SH3 is mostly borked and there is only so much Stiebler and I can do about that. Tiny changes in one variable often have large effects and SH3 unfortunately defaults to stormy weather at least 65% of the time. Reece, if you are not getting enough wind and rain, you can try editing the campaign_.mis files. RWF sets PrecipRand and WindRand to 0, you can try settings of 1 or 2 to see if that makes a difference. Also, the weather tends to change more in the fall and spring than in summer.
Second, keep in mind that this is an early release. We plan to release updates but want to first get some initial feedback and also take a break from constant testing. Testing a weather mod is not like testing a new skin, as we have to run many sample patrols that last several weeks in game time--exhausting! If enough people feel that the weather has become too sedate we will certainly look into adjusting the settings.
Dekessey--Unfortunately, rain and wind are tied together in SH3 so that rain (especailly heavy rain) automatically produces an increase in wind. However, we think we have been successful in decreasing the rate of wind change so that a rain storm no longer automatically means an increase in your wind to 15 m/sec. I have personally seen rain with wind as little as 7 m/sec. OTOH, heavy rain almost always results in wind of 15 m/sec.
We are also interested in knowing if anyone observes (relatively) gradual wind increases or decreases over a couple of hours of game play. Stock SH3 produces virtually instantaneous wind changes, but my testing with RWF occasionally revealed slower wind changes. However, Stiebler and another tester have not seen this with RWF.
Finally, I want to publicly thank Stiebler for allowing me to help him out with the RWF mod. I believe he has long wanted to do something about the weather in SH3 but could not find anyone else to help him. I also wanted to do something about the weather, but since I had no coding or modding experience I knew I would not be able to do anything about it myself. Stiebler saw one of my posts whining about the weather, mentioned he had looked into it a long time ago, but that no one else seemed to be interested in helping. I volunteered my "services" and away we went!
