Casentino Rally Italy - rain and grass and vao and so on... 1.0

Just what I did to make the track a bit nicer, would be happy if it is useful for others as well.
All credits go to the original creators of course.

• You should be able to copy the files straight into you assetto corsa folder as long as you have the track installed. It will ask to override - backup your track if you want to keep the original files.

• If the new grass won't show check your assetto corsa folder: extension/textures/grass_fx. You should have a "highlands.dds" file in there, otherwise no grassFX.
