How to achieve dynamic rain drops (and water drops) in 3DS Max for games or Unity?
Watch some photos of my point below:
Have a look at the wet body of this car in NFS Rivals:
Just look at the dynamic water drops in the Project C.A.R.S photo below:

Then we have GranTurismo here, watch the tiny water drops in the Project C.A.R.S screenshot:
This is a photo that should be watched, look at GTA V's rain drops:

I know programming, I've used Unity3D and I've used 3DS Max for a while, I also know it is hard to achieve these shaders but everything today is almost hard to get. So please express a way to get such effect for my games if possible.
