Super great guide - I'm paying an obscene amount of money to a university and learned more following your tutorial than I have in 8 weeks of class. Thanks man!
Thanks for dropping by Dean! Ive been having a blast playing around with this lately (hence the disco fog XD) but yeah, its very cool :) Much love homie
Jesus, i was watching somebody elses 3 part tut on vol fog, then i saw yours in the suggestion list ... and its not only just 1 shorter video but its 1000 x better, that other guy was spwning 500 fog particles ..wtf RIP FPS !!! lol When he said he gonna spawn the max cpu particles i was like ... ok this guy is clearly not knowing wtf he is doing XD thx man yours works PERFECT with just 5 particles
Are you sure the shader complexity you showed was correct? My fog is pretty much on the red and pink in the scale. Maybe I did something wrong, but I dont think so. I would think this effect is pretty expensive .
@@janmicka5272 you need to add exponentialheightfog actor to your map from actors list. Place actors (by default on the left side of your viewport, has stuff like recently placed, geometry, etc and a list of stuff related to that particular filter), you'll find it under visual effects or if you use search bar on top of it as soon as you type exp you should have exponential height fog actor and just add it to your map.
@@lazytopaz Thank you, I did all as you asked, placed expo. height fog, turned on volumetric fog as well. put both niagara and cascade version of particle and both are just transparent. Any ideas what am I missing?
@@janmicka5272 hmm It might be silly of me for not pointing it out : but adding directional light (if you don't have one) and in its properties add cast volumetric shadows on, it also might need to be switched to being a movable (stationary might work too but needs light rebuild to take effect, for learning/testing purposes preview quality is best), keep in mind that volumetric scattering intensity value in that light is the one that bumps the effect of the fog and the effect of the particle on the screen + in exp. h. fog there are several properties you'll need to tweak for better effect like fog density, second data fog density...basically Exponential H. Fog Component properties + volumetric fog properties both of which sit in expo. height fog. Hope my explanation is good enough.
Thanks, this works well, but I am having trouble keeping the particles visible at a distance. They seem to disappear at a pretty near distance and none of the settings I can find affect that.
EDIT: I missed a step -- (watch the video at a slower playback it really helps) He highlights the material, then goes into details > material > material domain and changes the dropdown to "Volume" Looked interesting, but sadly you lost me at 5 minutes in, went to plug the extinction scalar value into the extinction node on the material and discovered mine does not have that option. Using version 4.24 hopefully not too much has changed...
Great video, can you show us how to make volumetric fog masking? like if there is some sort of fog repeler and it just masks the volumetric fog area to be visible?
You might have the ExponentialHeightFog > Volumetric check box turned off, or you might have it on but potentially have 2x ExponentialHeightFog in your level
There is also a bug or changed setting in newer engine versions, where you have to set the material to be lit, or nothing shows. Still looking for a fix so I can use it in unlit.
Hi, i'm following your tutorial but when i place my particle in the world, nothing appears, and I don't know why. I work on UE4.21 Somebody can help me please?
Great tutorial. I've adopted this approach but am having the issue that when the player moves away from the particle system - the fog cloud fades out and disappears. I would like the fog cloud to remain no matter what the camera distance from it. There must be some occlusion setting for this i am just not finding?
EDIT: This has now been fixed and Jack sorted out my issue with the wrong pack! Thank you Jack Jack you've linked to the wrong texture pack in your description. I have discovered this after purchasing the pack and it does not contain the assets needed for this tutorial. Can you please amend the description. I am also going to email you separately to request a refund.
Looks good to me. This worked out a bit different for me. For starters its visible but it appears stretched like in 15:47. Also they appear or fade in too fast.
Awesome video as always. Thanks. You're changing the alpha over life in the Particle System, yet there is no Particle Colour node in the Material. How does that work? Have I missed a step? Cheers
I switched the Extinction Multiplier with Particle Colour Alpha and it works a treat :) You could also hook Particle Colour RGB in the Material to drive the Fog colour through the Particle System :)
Sorry for late reply! You're totally right, it absolutely slipped my mind that I wasn't even using particle color in the material XD I just gave it a go and your method works fantastically, so thanks so much for the tip!
@@underscore00 no worries. Thanks for you videos. Ive been a VFX artist in the games industry for 20 years, and your videos are teaching me new things. Every day is a school day. Really looking forward to your future videos. Awesome job!
Thanks for this. It’s super cheap like you said which is perfect. Unfortunately when I scale up to large values (10000) it breaks , is it a buffer issue ?
For people who seeing nothing when put the Particles into the scene, the solution is: you forgot to put 1 in Default Value in the Extinction param ! :)
@@Mowroze That's what one could think, but it wasn't the case. Same for other volumetric fog & cloud examples, none of them produce a cloud, unless the material is set in lit mode. Probably a bug in the newer engine versions 🤔 I've tried and googled every fix, other people have had the same issue. Workaround is to change the mat to lit. Please let me know if someone finds a way to to fix it.
@@freezEwareI hope you will find a way, I never used the new version for the moment because with my job I'm too busy but if I'll install it, I'll try this tuto and let you know if I can fix it !
I hear the volumetric fog eats up alot of hardware performance. Is there a certain feature that effects this so I can adjust it to make it less strenuous on frame rate and hardware?
I had added the effect to the player as an attempt to reduce performance cost adding the effect to the whole world. It works, but is slow to rebuild after leaving the distance of the cylinder. Should I just place this effect all over the map? Thanks, @underscore.
Hey mate, thanks for the video very helpful. I have question tho..... I'm trying to use this tutorial to make shifting nebula formations in a space environment I am working on. Everything works as in your video but the fog only appear on camera when you are really close to it. I want these particle systems to be background elements and so far away from the camera. Is there a setting somewhere to increase visibility in regards to distance from camera?>?>
Is there a way to disable global fog and just have the fog in one localised area? I've noticed that adding an Exponential Height Fog actor to my landscape, it adds a global haze to everything alongside the localised particle system. I can't find a way to remove the global haze in a way that doesn't also remove the localised fog effect. Any idea how to achieve this?
tut was great--feel like I've been looking for this for a year! everything was working well until I suddenly got these error x3018's for VolumetricCloud and VolumetricFogVoxeliztion invalid subscript vertex id
Hey! Question - the shader complexity is red for me when I check the optimization. Would you happen to know what the issue is and how to fix it? Thanks, great tut!
Hi, thanks for watching! Yeah in the version that this was made with, volumetrics dont appear in shader complexity which is why my scene looks green in the video. Red is OK, but it does indicate a performance hit. Pink/White is bad, so if youre seeing any pink or white, I recommend looking for ways to optimize. Hope that helps! :)
A little criticism if you can take it. Some of us are still learning UE and it would be nice if you could sloooow waaay down to explain each step. For instance, there are two Object positions, and selecting the wrong one would throw everything off.
Yeah, sorry for the fast pace! I dont like tutorials that are slow or drag on too long so I try to be snappy. I know it can make following along hard, but youtube has controls to slow down the video to 0.5x or 0.25x speed, which should help :)
my fog is flickering off and on in the viewport and game and It's not the distance values or etc as far as I'm aware of because it is visible at times. I don't know how to fix this please can someone help me, thanks.
now for the most important question how the frick do i reverse the effect. i want my forest to be foggy but there is a house and i don' want fog to go indoors
If you've done everything right until the particle system, but still see nothing, press Alt+F in your viewport to show Fog, as it is probably disabled by default ;)
I've made a laser using a very narrow, extremely bright spotlight. However, its illumination of the fog is very pixelated. Does anyone know a way to fix that?
Yes, you can use a skeletal mesh. Check out Marvel Master on youtube. He also shows how to add collision to the fog, making it swirl about as a character moves through it.
Potentially, yes. You could make them show/hide based on player proximity and save a lot of overhead that way; thats just an idea off the top of my head.
Not work for me.(4.25.3) Particle system doen't spawn fogcloud particles. If you want fix this, adding exponential heightfog, checking volumetric fog value to true. that is a working
Doing this in the new 5.0 Beta, the Sexy Godrays are there but so friggin faint they're hard to see/notice unless looking for them. Anyone have any ideas?
You might need to go into plugins (or maybe somewhere in project settings) and enable volumetrics. Let me know if thats not the case, I'll try to get to the bottom of the issue :)
@@underscore00 I enabled them in plugins. I redid it and I am still getting the same results. What happens is the effect plays, it has box outlines, but it is invisible and cannot be seen.
This is the easiest way.... and no one really uses it, because it is too demanding for the graphic cards and if you stay in that area for too long, it can overheat the PC
@@underscore00 Nope! And was able to get it to function on my main maps. Just gotta make sure that the Exponential Height Fog is there and always has Volumetric ON. Thanks much!
