The Fresnel Node | 5-Minute Materials [UE4]

[@TinyWorlds]

In Unreal Engine 5.2+ there's an additional step to enable refraction, you have to change the "Refraction Method" in the Details panel to something besides "None".

[@xylvnking]

Fresnel is super clutch for unlit stuff too, darkening the edges of unlit style assets can give the impression of shadows, especially when combined with AO

[@aburak621]

Amazing video as always! Example use cases were extremely interesting.

[@PrismaticaDev]

Thank you very much :) I wish I had mode time to explain EVERY use case - maybe I'll have to save it for 5-Hour Materials instead ;)

[@Jukerlaw]

Even tho i alr knew this long ago. Seeing another person’s pov and his practical usage is really knowledgeable. Hope u can share ur knowledge and how u use them with other nodes as well. Cheer.

Crikey. These are awesome.

Maestro here. Another good tutorial as always

[@PrismaticaDev]

Glad you enjoy it my dude :) Loved your recent one about buoyancy!

[@stevenholden667]

I can't seem to get the refraction as seen at 3:20 working on UE 5.0.1. I have set up everything as seen on here, but it will not work, and my object is completely transparent with no fresnel. Everything works up to this point though.

[@stevenholden667]

After trying everything, I realized my scalability was set to medium. Refractions only work on scalability of high and above.

Haha better late than never! :P

Love your videos, you’re easy to understand and the music in the background is so soothing

[@TheSiloZen]

Love this tutorial, made so much stuff clearer, thank you!

3:50 Also very good for shockwaves for VFX.

Well done your super underrated

I appreciate that :) Don't forget to share with a friend!

Wow.. that's an amazing node, I'm gonna play around with it as soon as my Trello allows me to 😆

[@lilouhaefner3352]

1:25 I don't know what happens behind the scenes for the fresnel node. If it uses a saturated dot product, though, the point on the mesh directly opposite the camera should be 0. This is because a vector AB doted with a vector BA returns a negative value, and the saturation clamps to a min value of 0. 3:25 You can actually see this here. The refraction is the least on both the area of the mesh facing toward the camera and the area of the mesh facing away from the camera. Just in case anyone needed to know. However, it probably won't matter if your material isn't two-sided.

[@sergiogonzalez2611]

thank you man you are very kind

[@PrismaticaDev]

No worries at all :) hope this helped!

[@Fokkusu]

Fresnel is so cool, thanks you for explaining the node ^-^,

[@PrismaticaDev]

Hope it comes in handy m'dude :)

[@Fokkusu]

@@PrismaticaDev oh it does, for Djinniya's Lamp we have in the throne room the ceiling that is glass and we have a parallax texture with space and stuff on it, we didnt have a good glass solution for the ceiling and the Fresnel literally saves the day :D

[@atique2545]

dude I am your biggest fan.

Your support is always appreciated

[@conniebarker3228]

thank you

[@craftedterrains3036]

i use the fresnel node on foliage - the further away something is, the darker they look. but thanks for the educational video :) got the idea from watching this video

[@IrocZIV]

Not sure what my issue was, but if someone else using UE5 can't get this working, try making a Material Instance and using that before you try and trouble shoot too much.

[@emorange]

Great presentation and BGM ：）

One of your videos kept popping up on my recommendations for more than a month and I was about to block this channel. I clicked it, and omg was I wrong? Finally youtube nail it, your videos are so perfect 100 out of 10! ❤❤❤❤

[@ilancohen7122]

thanks for the tutorial. how to use Fresnel with alembic file import as a geometry cache? it seems to overlook the camera viewing angle. I've imported a rotating and deforming mesh as a geometry cache and when its rotate the Fresnel effect is rotating along with the mesh. I'm looking for a node that keeps the Fresnel at the viewing angle. any suggestion?

[@magnuswootton6181]

fresnel actually controls subsurface scattering.

how did you made this panning souls? Im struggling with this fake depth material, hope you know the solution. Earned my sub! Keep moving!

[@alejandrocambraherrera8242]

I have no idea how fresnel actually works in UE4, but my guess is that it simply calculates the inverted dot product of camera vector and surface normals (1 - dot(a,b)). Assuming Iʼm correct, what happens in the face of the object that you donʼt see would be exactly the same as what happens in the face you do see.

[@PrismaticaDev]

Haha I figured as much - but there's no way to REALLY know... right? ;)

Would be slightly better if you didn't block so much of the screen with foreground elements.

[@PrismaticaDev]

Very good point, although the trees are there to block the ugly black box since I use an Ultrawide 2K monitor which is TERRIBLE for video/streaming hahaha. I might stick to a 1080 crop in the future but then Ill always end up saying ‘you need to go to the dropdown menu on the left and click THIS’ without realising no one can see it

[@PhantomZtryker]
