Mysterious Fog Volume Disapearing

[Phylik]

Hello. I made a little Frontend Level which looks a bit better than a empty Cube.
But I got the following problem:

I used 2 Fog Volumes (1 Constant Density Volume and 1 Linear Halfspace Density Volume) which look fine inside the editor. They also look fine if i play in editor. But if i play it on PC they are not visible.

Play in editor:

I am pretty sure that the problem is simple but I did not find a solution on my own.


Thanks for any answers.

I'm also having problems with fog volumes. At some point some started to disappear depending on where the camera is aimed ( the fog-volume itself should still be in view tho ).

Nobody knows what could be wrong ?

Do you have anything between the fog and the void? I've noticed that the fog tends to disappear completely in-game if nothing is behind it.

[Phylik]

No. I haven´t. I will put a black Skydome behind it. Thank you. I´ll tell you if it worked.

It seems not to work

Got any good solution yet? If so please tell me how.

From my observations,
1) UDK seems to render "clear depth" differently when in editor and when in game. Clear depth is set to ZFar in editor but ZNear in game, as a result, the fog is not painted!
2) Sometimes this behavior may differ depending on the video cards.

3) DX11 renderer produces correct result but DX9 renderer doesn't.
