DDDK and Fog Volumes

Is HeightFog the only fog option available?  Placing any other type (i.e. FogVolumeSpherical) in the level template doesn't seem to do anything.

I would read this https://api.unrealengine.com/udk/Three/FogVolumes.html. It all should work though.

The fog volumes for DD do not work as the version of UE3 DD is on is older and those features were disabled because they're very performance heavy.  Use Height fog actors and change their density and start / stop distances.  You can also create a type of pseudo fog with a particle emitter, there are a few premade examples in the many level packages if you search for them.
