When you do something what isn't supposed to be done, then it is a bit difficult, and compromises might have to be done. Right now I'm trying to find best balance for reflectiveness, and it is really hard because it also affects color, in general huge impact for the look. In this example you can see that it looks good from this angle, well at least it looks ok to me, some might find it wrong maybe, IDK But from opposite direction and especially with a camera close to the surface it goes wrong, reflections aren't fully correct, and this would cause annoying flickering in some cases: It would also look not too awesome in replay because when the water is reflecting surroundings rather well, but not the car then it is not complete. Also car ambient underbody shadow might get messed up. So don't demand much. Compromises has to be done, and I'm doing it just for the few folks who actually are dying to get a little bit of "wet like" driving, even if it is just a modded placebo factor, but placebo can get pretty good at a times. Loosing 99percent of grip when going over the puddle certainly adds some.
