Hey gang! In today's episode of 5-Minute Materials we're looking at the Fresnel node! This is a really handy node to add to your arsenal of shader tricks. It can be used for water shaders, glass, faking depth inside opaque materials, sick car paint jobs and much more!

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".

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

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

@Jukerlaw 3 года назад

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.

@aburak621 3 года назад

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

@PrismaticaDev 3 года назад

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 ;)

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

@ilancohen7122 2 года назад

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?

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.

@stevenholden667 2 года назад

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 2 года назад

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

@alejandrocambraherrera8242 3 года назад

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 3 года назад

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 3 года назад

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

@lilouhaefner3352 2 года назад

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.
