Fog of War setting problem

So, i have Fog of War. How can i hide the tree, if tree covered by fog. Screenshots can say more about the problem then my words!

We need more information about what is your fog of war.
How do you handle it ?

It is a plane mesh with translucent material. Also, i have fog substruct material for clearing location.

handle without “Disable Depth test” gives me this result. What kind of additional information do you need?
