Hi all, I am having a question about the "wet surfaces". Never tried it before so the question might be kind of very generic. And as far as I see it is also valid for FSX. I made a material according to the SDK and applied it to the ground polygons and it works fine so far. The only problem which I could not sort out up to now is that I am not able to control the appearance of the "wet polygons". They are visible also in dry conditions. The settings in the material editor should in my understanding control the behaviour according to precipitation but with the values (see attachment) I do not see any effect. What did I miss?
