1 thing I noticed that may be causing some issues (not certain if directly related to this) is your version of climates of tamriel. Supreme storms COT integration is designed for the 3.1 version of climates and not the most recent one. As far as the rain textures go you could try disabling the rain in enbseries.ini. My ini for rain looks like the below. with this you could then try to install custom rain textures if it still does not work. [RAIN]IgnoreWeatherSystem=trueEnable=falseEnableAntialiasing=falseEnableSupersampling=trueMotionStretch=0.7MotionTransparency=0.12
