Hi all,

I am trying to make an effect where the player can not see more than a few meters in front of them. I know that there are various ways to stop actors being drawn when they are at a certain distance, but what I am looking for is a way to make visibility fade out slightly more gradually. I suspect I might have to do something with the atmospheric fog, but I am unsure about what settings I would change to make the fog impossible to see through and to make the fog very close to the player. Can anyone give me a pointer as to what kind of settings I would need to change to achieve this effect?

Thanks in advance!

You know, you could just search “ue4 volumetric fog” on Youtube…

Here you go: [Volumetric Fog tutorial Unreal Engine 4.16 - YouTube](https://www.youtube.com/watch?v=vBYKabEFNVg)

Increase it until you’re happy with it.

Just know that it may _severely_ impact performance the closer you get to the player, because it has to render everything else through a veil of 90% transparency instead of opaque. Press F7 or whatever it is to see the shader complexity, to see if it bogs down the performance too much in regards to the hardware/platform you’re targetting.

Thanks, seems to be exactly what I am looking for. Thanks for the pointer. I will try this out when I get a chance.

Oh also, if I combined this with a culling volume or whatever to stop drawing actors too far away could that help performance?
