For those newbies wondering what he did at 2:47, he put in a Constant3Vector.

For anyone who can't see Fog you need to also have ExponentialHeightFog added as well and the Checkbox "Volumentric Fog" in its properties ticked, then your Cube should show fog.

RIGHT, if like me you are wondering why this isin't working for you, at 0:28 in the video he specifically says TURN ON VOLUMETRIC FOG...yeah...make sure to do that.

If anyone else is wondering what happened at 2:47, you can hold down the number 3 and then left click on the background to add a Constant3Vector. 1, 2, and 4 work respectively.

If you're going to use hotkeys, can you at least say what hotkeys you're using?

[simviz_net]

It's pleasing to see some of the models that I'm made and also selling on Unreal Marketplace in some tutorial on Youtube ;D Great tutorial btw ;)

[Lorecastapendragon]

what the value thing called at @3:00 i cant find it anywhere, its a constant, hold down one then left click mouse on the graph

[asiangreg]

it only works when shadows are set to high

[mattlox]

They can also double as Dark souls fog gates lol

Will take a look through this soon, seems very handy. I was using the Local Height Fog and it causes insane amounts of crashes with it in 5.3.2 sadly, heard the bug was fixed in 5.4 but not tried .

Thank you for the vid. I'd love a tutorial on fog cards or particles--so you can have some animated slow rolling fog that isn't perfectly flat. Cheers!

[MrMOTDIT]

the simplest solutions are always the best, it's hard to beat that!

Thank you for the tutorial Ryan, I was trying to find A way to make a scary area in my game, that was very helpful.
It will be nice for the future to tell us if this is going to be a high cost. Is it going to effect frames, what is rely on, ram or GPU etc. :) for the frame sake. As I know Volumetric Fog is very costly for frames.
A grate video as always. Thank you

@RyanLaley Thank you for the lesson!
How to make a fog area in the shape of a mesh?
Not a square? :)

[davidcroucher]

Great tutorial, thanks. Anyone have an idea how to do the opposite? Have the fog fill the whole map except for one area? I'm doing a level with interior and exterior gameplay. I want the fog outside, but not inside.

[ArtandAllThat]

How do you do this when your only option is substrate materials now?

[MatthewGDunlap]

I did a lot of testing with this trying to make a dust cloud for an asteroid belt. Even using a sphere mask on a solid shape will cause a fog effect within the masked area, I ended up using a dynamic mesh to create a torus, with sphere masks on the material. Are there any ways to have shadows affect the fog, like an object passing between the light source and the fog area?

[CrimsonWoods]

Very informative. Are there ways to make specific points dissipate the fog?

[miloszgierczak]

whatws the better solution? To use volumetric fog with static cube volume or to use a particle system with volumetric material aplied? I have seen hey use both methods and im wondering with is better

Hi i have a question I want to record my game screen. I know there is a 'TAKE RECORDER' function, but I wanted to ask if you know of a blueprint node that allows this to be executed by pressing a button in the UI. can you answer me?
