How to achieve a clean Fog Depth Effect ?

[gritty sonnet]

Hey everyone, this might be a question suited for #✨┃vfx-and-particles , #archived-shaders , and #archived-urp also, but it seemed fitting to #💥┃post-processing the most.

I've been trying to make a Fog effect for which I need to work in horizontal Depth, i'm trying to make it look thick so that objects fade in nicely, and to hide any pop-in from afar, aswell as for the artistic touch it brings.

I really like how they did it in #drive e.g. https://youtu.be/fhrIH6gir04

Though I have not been capable of reproducing a similar effect, either it be through Shaders, Particles, and other means I've tried.

The only real limitation I have is that we use the Curved World shader, though a Shadergraph Node exists to apply it to existing Shaders.

If anyone had any insight on the subject I'd greatly appreciate it ! 🙂 Thank you very much

It looks like bog-standard environmental fog

@autumn elm do you mean it's the Render Pipelines basic fog ? Everytime I tried setting it up it always had problems with the skybox or particles and such, we could see outlines in the fog from very very far

[autumn elm]

That's not a problem in your example because the horizon seems to be never shown

The common workaround for horizon outlines is to blend sky color with skybox color

Or a simpler method to paint with the fog color on the skybox

indeed this exemple differs a bit from what I'm trying to do and yeah our skybox is a gradient and it wasn't working well

@autumn elm though I didn't know you could paint the skybox with additive fog color, no idea how to do it, i'll have to look

[autumn elm]

A skybox can be anything, really
If your gradient matches the fog, it should blend better
Though you mentioned curved world so I assume that means we can't always rely on distant objects being at the horizon as they normally would

unfortunately yes

Guess your best bet is to look for the kind of skybox fade effect that's compatible to your rendering pipeline

Or some other kind of fog solution

The Drive game gets by with very limited technology as it strategically hides its flaws
