Thank you. It was really helpful. The dust really helps lift the scene. I use it all the time
Glad you liked the final effect!
Hey my friend :) even you here. Going to try it. Thank you Gono
@@Sciontidesign Hey man! I am always floating about.
Thank you so much for the video tutorial!
I went and changed things up a bit from what you instructed, including using an actual texture for my fog instead of a particle color node - I'm going for that Silent Hill 2 & 3 look. You got me to where I needed to be for that, thank you! :D
Hey, glad to hear that! Good luck with your project 😉
This was really helpful. Thanks!

Nice video :) thx
Thank you, glad you liked it! ;)
Hi! Quick question, i would really appreciate some help! I have a flickering light in a dark scene (my light has a Light Function Material) , when I activate the volumetric fog what happens is that the light flickers, but the volumetric fog retains the light "bloom" even when it is turned off. So what i get is a flickering light that doesn't really affect the volumetric fog, it acts as if the light never turns off. Btw this doesn't work with Rectangle Lights, the other lights work just fine with volumetrics
Awesome, Looks great! Will this work with RayTraced translucency and depth of field?
Didn't check specifically that, anyway the project had ray tracing enabled, so it should work with RT
Amazing video and I love the detail in the video and in the fog itself! I just had one question, though: Is there anyway to resize this so it fits over a larger area of the map? Everytime I change some of the settings, it just makes the particle sizes larger and more spread out. Thanks and keep up the great work!
You can increase the size of the box inside which the particles spawn, together with the spawn rate. Be aware that it has performance implications, if you have a character or a camera moving, it would be better to move the fog instead of expanding it to the whole level
@@gonoshift Oh, so have it move depending on the position of the player/camera? That's a great idea I didn't think of... good call!
I'm subscribing to your video before watching it - let's see if you can keep it ;)
ahah let me know how it goes!
does it work with static light?
Superb ❤️ Please make a match move tutorial unreal engine 5.thank you ❤️🙏💓
Thank you! What do you mean with match move tutorial?
so following along I can get it to work in the default lit view however it doesn't seem to work in the path tracing mode just large black cubes :( any ideas how to fix this at all?
Try with the new Local Fog Volumes: th-cam.com/video/2J7X-orWU6s/w-d-xo.html
Thanks for the tutorial. But in Shader Complexity view mode It says that the shader is extremely complex. Is it fine for the for or there might be other workarounds to let it be less complex?
For those who couldn't see any fog - there might be a problem with the Engine Graphics Scalability: Shadows must be set on High, after you would set Shadows to High fog will appear. If its not - than you have some other problem.
When working with particles, especially volumetrics, attention to performance should always be paid. Use bounds in an efficient way (check out this video where I explain how they work th-cam.com/video/4mpyhve75GQ/w-d-xo.html)
And consider making the system follow the actor instead of filling the whole level
Doing this in 5.1 just moments ago. Tutorial looks great and exactly something I needed, but I have run into a major snag. Followed along the tutorial perfectly, been over it almost a dozen times to make sure I did it all correctly, but at the end I can't get anything to show up. No fog, no dust particles, nothing. The dust particles worked by themselves but when added with the second (fog) emitter, nothing appears. First thing I did was make sure "Volumetric Fog" box was checked and it is. I even tried the setup in an entirely brand new blank project but same issue. Emitter is present, and, when selected, highlights where the fog/dust should be, but there is nothing visible.
Heya, maybe your particles are too small? Try making the particles bigger in the Niagara Emitter by changing their size, and be sure to not use a color with alpha too low. If you still can't see them probably there's some project setting wrong
@@gonoshift I tried making the particles bigger, and also tried changing the color (in your tutorial you never changed the color of the "Fog" emitter in the system, but I tried changing the color anyway) but neither helped or seemed to do anything at all. If there is a setting wrong I have no clue which one.
I tried it in a fresh brand new project and it still is showing nothing. There must be something different between Unreal 5.1 (what I'm using) and 5.03 (which I think your video uses). What I find really strange is I tried using a different material than the one we made for the Fog, and when I do it suddenly works. But the material is made exactly perfectly like yours in the video. I'm completely at a loss.
@@victorgross3722 Double check if the material has the domain set to "Surface", blend mode to "Additive", shading model to "Unlit" and the "Two sided" option checked
I tried it on 5.1 and it works, so you probably missed a step unless you are using it in a very dark area or with shadows. For me this solutions to fog doesnt work properly since, for some reason, decided not to work under the shadows of my trees, but it works under the direct light. Recheck if you missed the step of fixing bounds since in 5.1 instead of a check box is a choose option under the Sim Target called "Calculate Bounds Mode" where you can change it.
@@gonoshift I have the material domain set to "Volume" and the blend mode set to "Additive" like you say to do in your video (around the 6:00 mark, I believe). And as Error 404 said I did notice that 5.1 has the fixing bounds a little different which I did notice and take into account so I know that is correct as well. Also, my scene is literally the empty 3rd person template, so I know its not shadows causing issues. I have at least managed to get the dust particles to show up properly like they should, but no sign of the fog itself.
how would I chagnge the fog particle color? I want it to be an opaque white
Hey, check the new video about local fog volumes, coloring options are covered! th-cam.com/video/2J7X-orWU6s/w-d-xo.html
It's an interesting approach but also looks to be quite demading. There's a lot of particles generated, even if on the GPU side. Wouldn't using this kind of fog for some larger areas be too much for the general performance?
Cheers!
Yes, making it large will surely have perf issues. I recommend everyone watching the new video about Local Fog Volumes, because they are easier and lighter to you use! th-cam.com/video/2J7X-orWU6s/w-d-xo.htmlsi=Z9XFwoVzc6joiWn_
@@gonoshift I saw that too, but I don't plan on using 5.4 just yet, so I was more interested in this method. Which of course doesn't mean I can't wait for them to polish the local fog feature as from what You've shown us it's limited to the point I wouldn't find any use of it in its current state :D
Cheers!
I see, idk about your needs but if you're referring to the camera distance, there's the cvar option to set it, you can make it persistent. If you're referring to the fog shape it could be easily fixed too 😉
Hey man! Nice tutorial, fog looks good, but it makes my FPS drop to single digits. Any idea why?
Hey, thank you! Your FPS are dropping probably because of a too big simulation box size eventually combined with an high particles spawn rate. Try lowering the spawn rate to see if it helps (it definetely should), and then find a sweet point between performance and visuals. Cheers!
I’m in UE 5.1 and it’s turning black. I’ve followed your tutorial to a t. Would appreciate any help :)
I converted the project to 5.1 and it's working. Try creating an empty project and check if its black, if its not then your initial project has some setting that is "conflicting" with the final effect
The material doesn't function properly on mine with the fog example. I'm not quite sure what's different but the values and setup seem the same just to try to replicate it but nothing makes the fog actually visible. I'm guessing its not the particle but the Material that's causing the issue. The sprite renderer displays other materials fine.
Have you checked the Volumetric Fog checkbox in the ExponentialHeightFog object (01:00 in the video)?
@@gonoshift Ah that worked. I thought my issue was gonna be somewhere in the latter half of the video. It's always a checkbox somewhere lol. Much appreciated.
@@phenik403 Yeah I hope that somehow in the future Epic finds a good way to implement suggestions to troubleshoot problems like this, where if you forget to check a checkbox nothing works :D
How can we get in touch with you directly for freelance work ?
You can reach me on Instagram, handle @gonoshift
I followed everything here to the end, but once i applied the Fog material nothing showed again. idk whats wrong. using 5.3
Check if happens also on a new project, probably you have something turned off.
@@gonoshift I'm having the same problem in VR 5.4 - have triple checked all steps
If you are on 5.4, try using the new Local Fog Volumes, check here: th-cam.com/video/2J7X-orWU6s/w-d-xo.html
Hm any ideas why my fog doesnt change color ?
Check out the new Local Fog Volumes video, I also cover coloring options there: th-cam.com/video/2J7X-orWU6s/w-d-xo.html
This is great, but has anyone found it stopped working in UE5.3? I just upgraded my project to 5.3 from 5.1, where it worked perfectly, but now it's invisible.
Hey Sean, try to delete all your atmospheric components (directional light, sky sphere, etc... ) and add them back again, be sure to double check all the settings shown in the video, especially the fog checkbox, it shoud work. I've just tried it in Unreal 5.3 and works.
I met the same problem in UE5.3, can you tell me how you solved it?
If you want to try 5.4, check out the new video about Local Fog Volumes, they are a lot easier to use! th-cam.com/video/2J7X-orWU6s/w-d-xo.html
@@gonoshift Thank you very much :D I found that I let Engine S calability Setting to the lowest before, which led to it not being displayed in it
Great video however the fog doesn't appear. The fog material seems to make the fog invisible
Edit: nvm i just had to enable Volumetric Fog on my exponential height fog
Thank you! Yeah, always be sure to double check the THOUSANDS of checkboxes and options, cause its easy to forget one somewhere 😉
