Distance fog is glitchy.

[UnrealWillNeverDie]

So I need help, if anyone can. I made a room have distance fog, the fog is very glitchy in an unbearable way. It makes horrid twisting and whatnot, here is an image:

Sorry if it is not visible enough..

need more input, settings you made, maybe this or an example map.

Chose a more easily distinguishable color for the fog. That picture will hopefully show the problem..

I dont see anything wrong. That is simply how Distance Fog works .

If you really want to make a room filled with thick fog you can better use the regular one created using Light actors. Downside of this is that it costs quite alot of performance. Even on fairly modern systems.

Distance Fog is really only good for either sky boxes, where you can control everything, or for creating a thin fog in the far distance to simulate a planet's atmosphere.

Hm. Well how come in UT2004 distancefog always look flawless? Those glitches are absent in ut2004 afaik..

This might be linked to the fact UT2004 uses a completely different and much powerful engine.

Although I see the glitch in your screenshot. Can we take a look at the map (or even just the room) itself?

This can be easily fixed by just upping the polycount, iirc fog is vertex based and can yield some strange result with very low poly areas.
just make a huge cylinder, and add some distance fog, it'll clip quite strangely.
regular (zone based) fog does not have this, because it appears to depend on lightmap quality.

Unreal lighting really depends on the scale of your texture.

If you scale that down to tile like crazy it may look a lot better for the fog at least. I'm just guessing on the fog though. I do know that super-tiled textures have spherical lighting with dynamic lights, instead of the weird Gouraud shading stuff
