As you can see, the zombie is affected by fog, but the world isn't. Also this causes the world to be cut off abruptly. I don't know if this is a feature, but it doesn't make sense why it would render like this. Also, as an added suggestion, maybe don't make the chunks fully stop rendering when they're farther than "fog_end"

For reference, I have smooth lighting, render distance set to 16 chunks, render clouds and beautiful skies. I have tried it with Fancy Graphics but nothing changed. The fog settings are:

Also, setting the fog type to "render" makes some farther chunks darker.

Now, I've searched for info on this before, but I haven't found anything about it on this website nor in the changelog.

EDIT: It happens on Windows 10 Edition as far as I know, my friends on PC confirmed it was an abrupt end and my friend on PS4 confirmed that the fog was working

Another example of it not working:

Notice how there's a smooth transition between clear and fog.
