Ray Tracing, Lumen and Path Tracing Explained | For Beginners

[@jurxzy]

It's always the smaller KZbinrs that explain these things the best. Well done.

[@TheUnrealForge]

Thanks mate, I'm glad you found this video useful.

[@eobiri]

The best explanation I have come across 🙏

[@TheUnrealForge]

I'm glad to hear that.

[@eobiri]

Thank you for making the video. I really appreciate 🙏 🎉

[@TheUnrealForge]

You're welcome, this video was important since there are no much videos about explaining the rendering pipelines.

[@WARES-ht9ww]

great explanation, may i know which version of ue uve used in this video ?

[@TheUnrealForge]

5.3 for Standalone Ray Tracing And 5.5 for Lumen and Path Tracing. Since path tracing and Lumen is updated in a new version of Unreal Engine.

4:22 it doesnt work with AMD? only nvidia?

[@TheUnrealForge]

Mostly works with Nvidia, but you can give it a try with AMD

[@MahmoudHamdyGad]

Great Video

[@TheUnrealForge]

Thank you❤️

[@geometry_of_sound]

Hello thanks for lesson...but i have not Standart Ray Traced in Global Illumination field (only Lumen, Screen Space, Plugin)...

[@TheUnrealForge]

It's only available in Unreal Engine 5.3

[@partedigital]

Thank you very much for the explanation, I have seen that at one point of yout video you could see water using path tracing, could it be that you have to activate something to visualise water using path tracing?

[@TheUnrealForge]

In 5.5 you can see water in the path tracing, and we can make water with Niagara system to make it visible in path tracing.

Do You have any tips for creating mirrors in Unreal 5.5? for example Mirror in small room, bathroom... clear, and clear reflections... ? Regars and happy new year :D

[@TheUnrealForge]

Yes, you just need a plane with glass material and enable lumen reflections. It usually works perfectly or I'll try to make videos on reflections next time.

[@TheUnrealForge]

And happy new year brother 😉

[@SoContempt]

such a good tutorial TUF!

[@TheUnrealForge]

Thank you bro😉

Before lumen and UE5 The first AAA game to adapt ray tracing was Metro Exodus and it looked amazing with simulated infinite light bounces while still performing better than modern games with raytracing or lumen. The issue with lumen currently is the over use of TSR and you can notice it on transparent objects like hair it becomes a noisy mess from a little distance. But using both baked lighting for static light while using lumen for dynamic light is the best way to get good results with very good performance. In 5.4 there is no Ray Traced reflection it has Screen space and Lumen reflections which looks way worse

[@TheUnrealForge]

You're absolutely right, i don't like lumen at all that's why i still use UE 5.3.

[@marcusp5345]

Wait. So Path Tracing no longer exists in UE 5.5? It’s just Lumen now?

[@TheUnrealForge]

Path Tracing is available in 5.5.1, you can try it, and it's really better than older versions.

[@outtoplay]

Awesome Lecture! Just found your channel... Liked and Sub'd 🍻

[@TheUnrealForge]

I'm glad it was helpful. And thank you so much for supporting 😉❤️

[@jbach]

Great overview for beginners. However I wish you would have clarified in more detail the differences between pathtracing and raytracing. And Raytracing is no longer an option for Global Illumination.

[@TheUnrealForge]

I will create a video about that with complete detail.

[@FantasyNero]

Sorry to say this Unreal Engine 5 Lumen is a bunch of Crap, basically, it's a Screen Space Light and Shadows also slowly interact when you move your camera making ghosting and shadow fades

[@TheUnrealForge]

Absolutely true, i miss Standalone Ray Tracing. It was best

[@yourlocalhuman3526]

Is this an AI genrated channel...

[@TheUnrealForge]

How unreal engine tutorials can be created with AI?

[@yourlocalhuman3526]

@TheUnrealForge your question was the 1st question I asked myself before I posted the comment but then I thought that maybe the clips were taken from another channel. I didn't expect a small channel to have this good production quality. Plus the voice is ai generated. Apologies if I'm wrong.
