I was literally just searching for good tutorials on this topic and this video was just published, thank you very much.

[@AWMMars]

One of the best lighting setup tutorials I've seen to date... thanks for creating this.

Superb tutorial, made unreal to make sense to me.

[@TheMark147]

still looking for tut videos about some topic and usually end up at this channel with best and most detailed explanation

[@kutto5017]

Excellent video thanks for posting

[@mahmoudskafi5425]

I watched the whole webinar to see how to render noise free images, this is the only thing he said he wont address at the end :D

[@sebastianestrada4690]

I am searching for the same. Do you recomend watching it even if he doesn't talk about noise resuction?

[@Orliqq]

well there are some delay options for each frame when exporting

[@AbdullahCross25]

You can use denoiser command in the console. Might work

[@samippudke]

😂

[@samippudke]

Is it more faster than path tracing?

[@lacilaci]

Fantastic tutorial. I wish he went through the render settings in more detail.

Hi Matthew. Really great tutorial . Near the beginning shouldn't Directional and Rect lights be set to Stationary instead of Movable (since the lights themselves aren't moving)?

[@Gasetasierra]

Thanks!

[@behrampatel3563]

Fantastic video Mathew ! There's so many teething problems with getting god quality animated sequences out of UE with Raytracing. This video will reduce those problems down by half. Please consider doing a follow up on rendering noise free passes as that will help many productions out. Cheers, b

[@MatthewDoyleArtist]

My pleasure. Glad it helped.

[@andereastjoe]

Nice tutorial. Thank you. 1 question: Does raytrace affect the output/playtime (exe)? Or it's only effect the working viewport and exporting to movie or still images. Thank You in advance

[@contrast3dvisual]

Make a part 2. 😉😉😉

[@Designguidetv]

Can I ask a quick question. I am using an instance of the glass material, however this and other reflective materials are not affected by lights. It is only taking the reflection and refraction of the space. How can I have a light source refracting in a glass object?

[@saxnguyen5657]

pls make a video about create emissive material that can light the scene when use raytracing, ty.

[@PauloSamurai]

Someday I'll get my high end GPU

[@chrinarai]

I feel like he should have mentioned that you can use gtx cards (1660 and better IIRC) for ray tracing with dx12 you just need to add -dx12 to the launcher shortcut and enable it in the render options.. For those that didn't shell out for rtx cards!

[@chrinarai]

I should add that this has just been added to the new version and you don't need to add the launcher details, just enable it as normal as long as you have up to date drivers

[@kenyong7595]

At 33:04 did you notice that the moment you turn on the translucent refraction, the image frame near the window immediately turned black. That happen to me as well. I need to turn off the translucent shadow to make it brighter. Does it mean we can't use translucent shadow

[@shaderkul]

Haha! To think I just started watching this on the UnrealFest portal literarily a few seconds ago!

[@MetalGearMk3]

BTW why do you need to set the post process volume to zero when they are disabled in the first place?

[@Mahm00dM0hanad]

I’m still waiting RTX on Twinmotion Unreal is awesome but way more time consuming for normal day to day architecture work

[@dampflokfreund]

What about DX12 Ultimate support, including DXR 1.1 ?

[@PrimiusLovin]

What's the max VRAM used while working on a project of this size? Is it already on the limits of the GPU used or does it still have room to spare in memory for something way bigger?

[@asianhavoc1872]

I have 8gb Vram....is it enough??

[@red4666]

Why is the wall so spotty? Is that some kind of ambient occlusion?

[@connorcovey6031]

Anytime I set ray tracing up and then restart it gets to 39% and then freezes and doesn't restart.......... This looks awesome and very useful, but because UE4 can be so fussy sometimes it looks like Unity it is. Thanks for the webinar.

[@KUBE.archvis]

Should we leave out the skylight while doing raytracing? It's so noisy and it wasn't really addressed. Thank you so much for this webinar! I've been struggling for weeks, trying to get my project to look presentable without baking.

[@MatthewDoyleArtist]

You can use multiple techniques for ambient/sky lighting. I tend to avoid using skylights in interior settings though.

[@MetalGearMk3]

real-time GI is still too slow, I hope they speed it up in the future. BTW great webinar I learnt so much from it.

[@DaDarkDragon]

what do you mean slow?

this is fantastic but i don't understand why my shadows looks very noisy,

[@Potatinized]

Any way to render out pathtracing as video? It's like free Vray. lol. I mean, c'mon.. we now can delay each frame in sequencer, why not have the ability to render out path tracing as well?

[@shortsculpts1175]

Does the ray tracing works only with rtx graphics card or it supports the gtx graphics card also ??

[@MatthewDoyleArtist]

I believe it works with GTX cards too (somewhat) but it will be slower as GTX cards do not have any of the hardware for ray tracing. It is all done in "software" in that case.

[@HelderP1337]

It works on GTX, but really slow.

[@gursimransingh8726]

i have heard that unreal also support ray tracing in non rtx cards so would a 1050 ti run ray tracing

[@gaminghood849]

I think it is not supported on the 1050 and 1050ti although I am not sure

[@jamaljamalwaziat1002]

It is supported on 1060 and higher but with alot of crush u can find the video in youtube

[@drum1548]

My mirror w Quality is horrible! Wish I could send you a print screen.. I don't know if the problem is me (I'm starting to learn ue5) or if it's my GPU rtx 3070. I know that my materials doesn't look at the same quality as yours. My mirror doesn't reflect my scene. My metals are creepy. I cannot see the details.. 🥺 I really don't know what to do

[@8liberate]

3ds Máx and Unreal Engine?

[@Silpheedx]

Lots of great information. BUT if I follow along with this my images are completely noisey AF. This is why you need to not cut out anything and show all the stuff you have to figure out a long the way.

[@drum1548]

What is your GPU card? I have bought RTX 3070 and my scene in viewport is not even near to this quality you have.. I am so frustrated! 🥺 What would you recommend, and do you think should be better to sell my GPU card? Because my scene quality sucks so much!

[@teidenzero]

What am I doing wrong? I'm getting 20fps with a Quadro6000 in the example project for this webinar

[@siminc7905]

are you on PC or laptop?

[@HelderP1337]

I doubt a Quadro6000 is good enough, I also get around 15fps on my 1080ti. You probably need a 2060 or above for this to run above 30.

[@benjamink5546]

Am I the only one who doesn't check why the windows light up before the rectangle lights come on? My BP Skysphere is glowing red.

[@ealendir6986]

Hi what if I open ray-tracing without rtx? I have gtx 1650 but I wonder can I achieve this results with just less fps? Is it harmful for my pc?

[@phynx1756]

Yes. More info on it below. Rtx uses new hardware for ray trace process boosting. These software updates are for those kinda cards so they can properly use the new hardware You can still very much use these lighting methods on older cards how ever they take longer to produce images. These cards are heavily marketed because this tech is old but the hardware is new and makes it able to reach real time. Hoped I helped have a good day

Too much complexity for Archviz. Waiting for this to be implemented into Twinmotion watered down to the very base needed settings.

[@kingarthur7250]

I have to say ..all this fuss over raytracing...and l turn it off all time on pc and dont miss it....nvidia used raytracing as an excuse to put prices up and to try to stop fps hitting 4k 144fps at which point no one will want a new gpu for years. If our hardware becomes to expensive just to run un needed ray tracing then dont bother with it. If l had to choose a high fps card or one with raytracing l would choose the cheaper fps one ..raytracing at moment is a expensive gimmick with nvidia doubling price using it as excuse.

[@jackwestcott615]

Idk, absolutely love ray tracing in most games, but it depends on the game as to whether it's worth the frame drop, Minecraft for instance look incredible with ray tracing on, and changed the game dramatically!

[@siminc7905]

Games use very MANY tricks to make games look close to realistic.Some of those tricks and code takes months or years to develop.Ray tracing is very taxing on hardware(games still need tweaks to be playable) but promises realism without tricks which means realism goes to a whole new level.This is especially important for artists and architects who just want realistic light with clicking a button.If you think gaming rtx cards are expensive,professional quadro rtx cards go for up to 5,000$

[@abckids3476]

Why the h*** didn't he go through getting rid of the noise. None of this is any good unless you can get rid of the noise. What a waist of time!

[@wilsione]

exactly..

[@behrampatel3563]

Add more samples, and delay time ? Use a plugin ( neat video ) to reduce in post. Hope multi GPU support comes soon

[@abckids3476]

@@behrampatel3563 I did use neat noise reducer in post. It's just not the same as getting it clear from the ue render. Il try more samples

[@MatthewDoyleArtist]

Sorry. Getting rid of noise is difficult. More samples helps, but in some cases it is very hard to elliminate. This is 1st gen tech, so expect it to get better. New cards coming very soon too.
