[UE4/UE5] TIPS - Local Volumetric Fog

Step-by-step tutorial available here : • [UE5 TUTO] Animated Lo...
Volumetric fog can be tricky to setup sometimes. Here a simple way to create local volumetric fog.
/!\ You need to have an "Exponential Height Fog" with "Volumetric fog" checked on your level to make it work. /!\

ObjectLocalBounds changed a little with it's outputs in 5.3. SIZE is now EXTENTS, and the DISTANCE bit might not come up in a search but it's in the D's under UTILITY for anyone that right clicks. I had no problem setting this up and it works as intended. Mille mercis pour ce tuto!

[@TorQueMoD]

I was so confused how this tutorial could be less than 30 seconds, but this is fantastic! Straight to the pont.

[@Drachendrac]

Worked for me quite well in UE 5.1. For anyone struggling: Look out that shadow quality is at least set to high, otherwise it is invisible, as well as having volumetric fog checked on the exponential height fog

[@nguyenphan4333]

Here's some tips to do if you're not getting the fog: 1. Make sure you have a HeightFog in your scene or any other variation. Make sure to enable the VolumetricFog in the details pannel of the Fog. 2. You can use LocalPosition node and use Local Position pin instead of getting the world absolute position and then transform it to local.

[@alexanderdimitrov7965]

tnx. you fix my problem

[@GameDevMikey]

Thanks buddy Trying to figure out how to reverse the effect, The fog appears when you're far away and fades as you get closer. 🤔🤔

[@LousyNine]

How do you get that ObjectLocalBounbs node. The only one I could find is the wrong one.

[@BadPracticeAutomation]

Absolutely amazing! I've tried a few fog tutorials but this one is the best yet!

[@staticbuilds7613]

The best tutorial format I have seen for this software

[@FromScratchStudios]

This is amazing! Thank you

[@bradicalmusic]

Cool stuff! Make sure your scalability settings (the gear in the upper right in UE5) are set high enough to see the fog. Otherwise it will be invisible

[@nottutorials2843]

All the parametres I found in the comments for my fog to work (UE 5.3.2) - Your level needs an ExponentialVolumetricFog, with "Volumetric fog" ticked, and Start distance > 0 - Shadow quality and scalabity setting set to "High" or more for your project - In the TransformPosition node, make sure you set up AbsoluteWorldSpace as Source and LocalSpace as Destination - In ObjectLocalBounds, use Extend for the Size parametre - Distance node is far down the list under "Utility" - AbsoluteWorldPostiion uses the first output "XYZ"

[@EFX612]

Amazing!

[@TheSonicfanx1]

I came back after like half a year and I finally got this to work. My issue was I didn't set the Transform Position to "Absolute Local Space to Local Space". It was on default settings so it never worked.

[@NebosvodGonzalez]

That looks very nice Love the God rays. Now pro tip if you want to make fog that looks absolutely insanely incredible like with vortexes swirling all around you and stuff you've got to use fluid ninja which does cost 40 bucks but come on it's totally worth it.

[@prodev4012]

fluid live or vfx version? also they're both 100 not 40. either way good info thanks!

[@NebosvodGonzalez]

I don't know just Fluid Ninja Looks Dope.

[@NebosvodGonzalez]

@@prodev4012 i don't know.

[@katanalevygames]

@@prodev4012 I picked up both when they first launched and were much cheaper. But I would still say they are worth the current asking price. They both have their own use cases - Live if you need objects to interact with it or VFX if you just need a static loop.

[@phrizee]

Thanx a lot, Bro!!!

[@anferneeee92]

This is by far the best, quickest AND easiest on volumetric fog. I know I've gotten this tutorial to work before but now I'm having the problem where it is invisible. I should have all the ExponentialHeightFog settings right but it makes no difference.

[@anferneeee92]

For anyone with the problem I previously mentioned. Make sure the TransformPosition node has 'Absolute World Space' as the SOURCE and 'Local Space' as the DESTINATION. Such a simple mistake, yet it stops the fog completely.

[@kirlesth9673]

@@anferneeee92 Thanks

[@usuariouser8545]

Thx!

[@NathanAkins]

Great video man, I've been wondering how it would be possible to achieve this effect without using a mesh's bounding box but rather use the actual shape of the mesh that would contain the volumetric fog?

[@Dhieen]

Amazing, i want more short tutorials

[@emreturkalp]

Thanks Michael.

[@HenrikoMagnifico]

Hi! For whatever reason the material appears completely invisible to me? I have double checked that I have done every correctly as in the video. I'm using Unreal 5.0.1

[@TheDavan619]

Hey, It works for me in UE5.0 like in the video, but only if I'm close to the fog cube. If I move the camera back a bit, the fog cube appears completely empty/invisible. Do you have a solution for this, or know what I might have done wrong? Thanks

[@Tubusy]

Another hitch may be having any Start Distance in your Height Fog -> Volumetric Fog. That fixed the mystery of the missing fog.

[@Pneumanon]

Man, why is it such a pain in the ass to set up volumentric fog in Unreal.

[@sandmeister26]

if you are having trouble getting this to work, I think it requires an ExponentialHeightFog actor, with "volumentric fog" enabled in your level

[@alexanderdimitrov7965]

tnx.. good job

[@DamienRamirez]

I am finding in UE5.1 I need to connect up the Emissive by using the base colour via a multiply & With a Scalar param defaulted to 1 for it to work & to change the colour of the fog. Guess that is intended now? because my old Fog materials that Do still work are not blended without Emissive connected.

[@vembdev]

Didn't work for me, but I missed that transformPosition in the material has to be worldspace to localspace, after that it worked.

[@thilinarupasinghe7968]

Great Tutorial but the Important thing is in the Description, it has to enable Exponential Height Fog -> Volumetric fog

Could be posible to do a noise mask animated with a panner to create a dust/ mist efect? this could come in handy to create nice small fog bank or background clouds been blown by wind that intrectas with the scene lighting

[@michael_g_art]

It's made and available on the channel. Thank you for your suggestion :)

[@yashmunankarmy4408]

Nicee

[@teodorteovasileva]

Followed the tutorial exactly, transform position is set from world to local, high and epic settings, fog distance has been checked, volumetric fog turned on, played with the opacity but still nothing. Any advice? :(

[@SuperFoxyPaws]

I'm not sure where to find the 'distance' node for the material. What are you using for that?

[@michael_g_art]

You just need to search for it and you will find it

[@SuperFoxyPaws]

@@michael_g_art found it! It was under utility. The method also worked a treat so thank heaps for the upload!

[@manulaatapattu9478]

if the shadow setting is less than high, the fog seems to disappear. Any workaround for this?

[@user-xn3zc8zw2b]

this is really good! thank you ! but Shadow shape are original actor 😢 in far distances

[@libortelupil7647]

It works for me, but only if camera is very close to the box (or inside). How to make it visible from the distance? Thanks.

[@UnrealQW]

There is Distance parameter in Exponential Height Fog

[@tolunaygenc]

Is there a way to increase draw distance specific to this fog ?

[@michael_g_art]

You have a parameter for this on you Exponential Height Fog

[@semiastyfx]

for some reason when added to a UE basic cube it dont work, any other mesh it works ok

[@maks_zharkov]

Would it work in UE4 27?

[@jhebadiasprunklefunk9243]

Kudos for making the quickest tutorial ever :D

[@victoralexandersilva5212]

there is no distance node in the new version of UE, sadly couldn't make it work

[@michael_g_art]

You have it, first node in the "Utility" category

you're right! so weird that doesn't appears when you text the name on the search bar, thanks!@@michael_g_art

[@NatesPlayzGamez]

hey dude, hoping you can help. i followed the BP, i have volumetric fog enabled.. but at 0.05 there is no fog. when i set the opacity to -0.1 the entire shape fills up with fog, but when i go in the postive, there is no fog..im baffled lol. any ideas?

[@Ukkoprkl]

You most likely have the TransformPosition from Local Space to World Space, so click it and change it from world to local.

[@NatesPlayzGamez]

@@Ukkoprkl ahh cool thanks man!! :)

[@tgykurtulus]

not worked; it paint brown the areas where i locate.

[@brocupsla4854]

cant see it? turn up the opacity

[@RmaNYouTube]

Dude this doesn't work in Unreal Engine 5.0 final release, can you elaborate on this? 🤔

[@michael_g_art]

It works for me, be sure to have a volumetric fog on your scene already and follow the graph. Be sure to use the "TransformPosition" and not the "Transform" only :)

[@Hero_B]

How do I pull up the 1-x? And are 0.5 and 2, parameters?

[@Hero_B]

Well I figured it out, and got made the blueprint exactly like in the vid, but I don't see the Parameter Groups option when applying to a cube, where you adjusted the Opacity or Colors. Any idea why?

[@dnaashoner5243]

1-x is one minus

[@sybexstudio]

Whats difference between this and local height fog?

[@michael_g_art]

I never used local height fog so I can't tell you, sorry

[@fletcherpoole1744]

I followed all the instructions. Volumetric fog: check, Abs World Position > Local in the mat etc. Still not working...Unreal 5

[@LiquidVeniym]

transformPosition in the material has to be worldspace to localspace

[@cryterion7770]

Yeah this didn't work for me. set it up exactly as you have it. I got the height fog as well as volumetric fog checked. no cigar.

[@dreadtrain2846]

Increase your settings to high or epic.

Just a heads up, this does not work in UE5. I'd appreciate it if you removed the UE5 tag in the video name.

[@michael_g_art]

As I said on Instagram, I just tried now on UE5 Preview2 and it works perfectly, so you should made a mistake. Be sure to plug the "TransformPosition" and set it correctly. The issue can come from there :)

[@mihaiwilson]

Just confirming, works fine in UE5 P2. Thanks Michael, this is fantastic!

[@michaelgalin7373]

How is the performance with this?

[@michael_g_art]

It depends on how you use it. It consumes as much as volumetric fog, unless you choose to increase the density.
