Cheap Fog in UE4 [Depth-mask post process]

IF YOU EXPERIENCE AN ARITHMETIC Float3/4 ERROR: You need to make sure that the SceneTexture and the Colour have the same float numbers (so either mask your SceneTexture to RGB using ComponentMask, or use a Float4 colour by holding 4 and left clicking)
IF your skybox is too bright, try this imgur.com/a/oK...
IF you experience visual issues/artifacts, try changing the Tonemapping settings in the Material
Hey everyone! Today we're making the simplest cheap fog in UE4 possible! It's extremely performant (free) and has a tonne of possibilities! It only takes a few minutes to set up and is even suitable for Cel-Shaded scenes.
This trick has been used in videogames since literally forever so it's about time you learned about it too :) This method requires the use of Deferred rendering as we're piggybacking on the Depth Buffer to achieve the effect.

[@Leonardorth.]

Ok, so for anyone having issues with this, you need to change the Blendable Location to "Before Tonemapping" in the material output node details. Everything else should be ok. You can also plug in the SceneTexture node into the A slot in the Lerp node. Just make sure to set the SceneTexture to PostProcessInput0.

You got a new subscriber for life! Don't know how to thank you..developing a game for a certain console and aiming for 60fps lock. Pretty much did all the optimizations i could on the GPU side and was left with removing atmospheric fog for the last 10frames I needed but that really impacted the feel of the maps and wasnt conveying the ambience I had in mind. With your cheap fog method, i got the same feeling/look as atmospheric fog back with ZERO hit. It's magic really. Thank you so much. Consulted a handfull of artists/ue4 pro's..no-one mentioned this solution.

Do you have any videos on KZbin that you can link to boost fps?? I have made a small anime game but I get 40-75 fps with a bunch of drops on low to. I have a 3070 also.

[@29Mozay29]

For anyone getting an error in UE5, add a component mask after the SceneTexture, click it's dropdown and check "B", and link it to the Lerp. Compiling what others have said so that this comment can be a one-stop solution: Click the Material output box and set the material domain to Post Process in the details panel. Then, search for "blendable" and change the Blendable Location to "Before Tonemapping".

Hey Closter! I'm not 100% sure personally, but I imagine Expo Height Fog would use some sort of volume calculation based on World Position, so would be more expensive than depth-fog like this tutorial. You could also do a World-Position based fog using the B channel of world position.

Any ideas on how I might fix this?

Not sure if there's any reason I shouldn't be doing this but it's stopped the vibrating issue for now at least :P

[@PrismaticaDev]

It's definitely possible - you could record the sun's position/angle etc and use that to Lerp the colour somehow... I'll give it a think! You can definitely do a distance-based colour gradient using a 3-colour-lerp node which would give the Among Trees/Firewatch look pretty well!

The main problem i run into is most tutorials assumes your not doing planets that your level is a flat traditional level mine is spherical where most shaders wont work not atleast edits.

Hi!, very good video and tutorial! One question, is it possible to get this effect somehow in a game with Unlit mode?

[@PapaSage]

I am not an expert on the matter, but I believe post-process effects are disabled in unlit mode because unlit mode removes all "lighting" effects so that you can clearly edit geometry. If you want your game to have an unlit appearance, I am afraid you will have to make all of your materials unlit. However, thankfully this tutorial still works with unlit materials. Recreating all of your materials can be a pain depending on how far you are into your project, but fortunately, the "unlit" view gives us a good peek at it, and helps us decide if it is worth it!

Hey Rob! The piss-wash colour is of your choice and you can adjust the opacity to your liking, as I show in the video. If you wanted a sharp cull line you could add a CheapContrast node before the Alpha of the lerp and set the contrast to 100+. Not sure why you'd want to, since it would look like hot garbage, but as with the colour of the effect, that one is on you! :) If you look a mile in to the forest and don't see any desaturation or colour shift, you might want to double check if you're on an alien planet where there is no atmosphere to gradually scatter light.
