Sure, I posted them in page 2, but here they are again: OFF -> ON
Edit: You're testing in bad conditions, there's no strong light to reflect from. This is a screenspace effect which means you have to see something bright for effect to work.

Also don't touch ma spaghet.
This looks correct. And it is visible, already proved. Your game setting have very low range of intensities, it can't look good at all with any reflection. The only chance for you to increase wet reflection parameters to 3.
I just copied whole Rudy preset and in wet surfaces categories set reflectionamount*** and bodyreflectionamount*** to 1, fresnel to 1. Thats all, effect is intense enough to see easily. And from the tests i gave to you it do work properly. SE do not have specular, so absolutely doesnt matter what surface it is, road or what else, only how dark or bright albedo texture is do influence inverse way amount of wet effect, but it's not that big reduce on practice. For me road do not disappear, i have no idea how is this possible at all, it's just additive effect. If road albedo is almost black, effect will be more intense, but it means your other objects are too bright by albedo, which i don't believe cause i saw albedo in the test builds. Undress character, set third person camera close enough and make it look to the sky, so wetness visible on the body. With 10a234 weather.
