How to make a fake refraction shader on unity shadergraph!

Blackholes, pools, fire, and many other staple effects of the gaming industry use this technique to achieve cheaper and more artistically flexible refractions. Many people call this either warp shaders, refraction shaders, or distortion shaders; but in the end, it's all the same technique!

Also, some people call it plasma shader. I refuse to acknowledge them.

LOL DUDE hahaha . Soo amazing . You have THEORY how it works you have actual quality explanation and is looking gorgeous... I have no words man, if you keep it up this channel will explode for our community. I can just say good job and that you are inspiration ! Very nice !!

One of the greatets tutorials I've seen thank you. Wish more people would explain things this deeply. Keep up the good work, loving it!

Thanks so much for this tutorial, man! (I know I'm commenting way after the fact) But I've been struggling to find some guidance on making distortion effects that'll work with Shuriken. Distortion is super easy in VFX Graph, but I'm updating older effects and don't want to re-create everything. You're a great teacher and I can't wait to check out your other tutorials.

Man this is awesome! Super useful and well explained. The tone was on point and I never had the need to skip parts!!

[gamehub]

great tut! Had a hard time understanding how distortion works, this shader worked nicely.

Amazing Tuto, Leo! Thanks again for share!

[rcant]

this is AAA material, you are a fine tech artist.

So what exactly is the particle system doing? Copying a premade one without showing any of the settings is confusing to say the least.

salve irmao do monark, tuto sensacional

The ground is suckered, the ground needs to learn some street smarts 😆

[christianchrustev]

is there a way to download that purple spinning effect from somewhere? i really like it, thanks!

[michaelsong]

Is it possible to distort transparent particles behind it? This seems to work only for opaque surfaces - every tutorial on distortion I've seen has this issue t-t

[lucasleite]

Ótimo tutorial Man. Pergunta, ainda não tive tempo de reproduzir e testar em meus projetos, mas esse tipo de distorção funciona bem utilizando VFX Graph com outras partículas atrás dessa distorção? Eu estava procurando algo que fizesse essa distorção sem deixar invisíveis as outras partículas atrás...

How can I create a Swirl black hole?
Can you make a tutorial?

Question: I see u are doing this in PBR Master, is it even possible to do it in sprite lit/unlit Master? I don't think this can be created in my 2D renderer that's using URP... right?

[Iridium.]

I did the exact same thing and it just wont distort nothing. Im using built in .
