    Wall of fog

    I want to create a rolling wall of fog like in this video.

    I have no idea where to start. I've read that you can't contain fog inside of a volume in UE4, so I'm not sure what to do.

    Don't expect to get this stuff with the standard tools. This is a pretty artist heavy effect that would require multiple 3d models of the basic fog shape, with textures that scroll in the direction that you want with a fluffy cloudy material and adding some particles to soften the edges. Its a pretty complex effect that is beyond the scope of a single forum post to explain.

    I suggest looking at the billowing cloud effect that is used in the elemental video above the volcano. That might give you a starting point on how that effect is created.

      Maybe FLEX can achieve such an effect. You´ll find a download link in this thread:
