Resource packs that add fog simply don't work. I have several packs purchased from the marketplace that add this type of fog to the game. But when I turn them on, they just don't work. The fog is not rendered, I tried several packages (Realism HD, True Realism, etc) and none of them seem to work.

From what I've been reading, in hotfix 1.21.41 they touched fog parameters and this could be the cause of this error. It is also worth mentioning that I tried it on multiple platforms (Xbox, Android and W10) and on none of them was I able to get the fog to work again.
