Wall of Fog / Smoke / Cloud

Hi

I want to make a wall of Fog / Smoke / Clouds as my visual boundaries of the map. I want to make it look cool and whispy like the cloud sample in the content examples (effects, sample 1.8). But I also don’t want it to be to performance heavy.
Can someone point me in a right direction or is the particle system the way to go? I’m also fairly new to the subject.

Thanks in advance and cheers!

Hello rouce,

There a number of ways to achieve fog. A large amount of particles will be taxing on any computer and may only be viable within the editor. We do have a section that covers different fog effects and their uses.

For your purposes I recommend exponential height fog because this adds dense fog at lower points of your level. This will allow for the character to exist within the confines of the fog. You can then set the distance from the camera that the fog is seen. This should create a boundary to your map.

Now, if you are wanting a wall of fog which is similar to a barrier then I recommend using fog sheets.

This method is slightly more involved and requires a basic knowledge of Blueprints.

Please look through the documentation and let me know if any of the three methods work for you.

thanks! I will certainly play around with the exponential height fog. I completely missed the FogSheets in my research. So I may settle for a combination of both. thank you very much!
