All about Fog Shader in Godot 4.0

In this video I explained about fudemental concept of fog shader in godot and how we can use that
This was only just one example of what you can do with volumetric fog shader in godot
I hope you can make other cool stuff with Fog in Godot 4.0

Thank you for doing so much about shaders for godot. There could never be enough sources about shaders IMO :)

[@mohsenzare2511]

Your welcome, I am happy to be able to help

[@thesynalice]

The FPS drop from 500 to 200 when you enable Volumetric Fog, Jesus Christ 😢

[@mohsenzare2511]

In the real game you should not bring the resolution of fog so high, unless the performance of this get better, This is just a tutorial about how you can use this shader, and obviously after you wrote your shader you should bring down the resolution of fog

[@dmas7749]

all i need is 60 FPS

[@MarkWallbridge]

Fantastic! Many thanks 👍👍

your welcome

good tutorial

[@mohsenzare2511]

Thanks

[@da_cat]

Very good tutorial, nice shader. But im going to stick with the simple vanilla fog material in Godot. I'm using small portions of fog to hide the origin of a river so this would be overkill for me

[@bam_bino__]

you'd use particles for that anyways

[@miusoft]

[@mattseaton5832]

Nice video. Why do you multiply the UV coordinates by noise_scale when sampling the noise texture? Isn't this the same as changing the frequency of the noise texture? Apparently not because the results don't look the same. But I expected them to be the same.

[@mohsenzare2511]

So about your question, no it is not same as changing noise frequency, By chaniging the uv, you are Distorting the the texture that you are sampling, watch my distortion shader: ruclips.net/video/dRu0vIkRLtw/видео.html

[@mattseaton5832]

@@mohsenzare2511 I'm not talking about adding noise to the uv. I'm taking only about scaling the uv by a constant

[@an4ximander]

Volumetric fog has similar effect right? I havent tried yet Godot 4, but I hope volumetric fog has enough options/settings ..so I wont have to get into shaders (haha)

[@Rogueixpresents]

what are the GPU/CPU/RAM/VRAM usage for this shader? are they expensive? I just have this weird mental image of godot, using shaders could be slow? thanks in advance!

[@mohsenzare2511]

Using shader by default is not slow, The performance depend on your shader code, If you write a good code it is fast, also if not use them godot will create automatically shaders for you in background

[@alexeykurilo4381]

Hello, is there any way to download the shader?

[@mohsenzare2511]

For now no, I will try to put them in Github for later

[@spirittek]

This is not working for me
