great video. suggestion: there's no video showing how UE4 ray tracing performs with laptop GPUs. please make us a video with a complex interior scene using an RTX laptop.
Hi. Loved it. However, I would like to see how many FPS you get with this. I have been testing RTX since the beta started and in very simple scenes, taking the care to use Raytrace switcher in the material nodes etc etc, I can barely get more than 15 FPS. I would be very interested in a tutorial, or a course ( I don't mind to go to Guilford for it) about optimization for the RTX pipeline. Thank you
Great video. I have 1 question about emissive material. I can't get rid of the noise I cannot remove the noise produced on the reflections by the emissive material. do you have any suggestions. ? if I increase the sampling of the reflections, nothing changes. it happens only from the emissives.if I put a light in place of the emissive mesh the problem disappears. Thank you
Hey, this is amazing work! I was just wondering, how did you manage to cut out the noise completely? The RT noise on reflections on the metallic sphere.
I tried to do this in a custom scene I made and it just looks unrealistic. I can't figure out why it's not working that well. I actually started it last week using the Ray tracing setup unreal has implemented in the latest version so you would think it should work out of the box
Hello! I have a question.Currently I use a GTX 1660 card for realtime archviz projects.I design it,bake it and package it.Then send it to my client.I am going to buy a RTX card next week.If I light the scene using rtx card with ray tracing and package it,will this be a problem to my clients when they run the packaged programme? Most of my clients have GTX,MX and intel HD graphic cards in their laptops.
Amazing Fabrice, nice one & thanks for giving info about this Laptop.....just keen to know one thing in 12:24 you were getting metallic feel in ceiling & floor bcoz no shadows were there, how to control that because it looks a bit different & won't seem to be a part of architecture.
I think that might have been screen space GI. I tried it recently and it's not bad. No contest between proper raytracing GI though. I love the level of control. I'm working hard on getting UE4 integrated into our pipeline. Currently using 3DS Max and Vray.
Bro I remember back when I first started following your videos not too long ago and now this is nuts
thanks man!: )
Have been experimenting with raytracing a bit, it's pretty crazy how incredible things look. Close to leaving arnold for good haha
Great work as always Fabrice, I’m using a similar spec laptop HP Omen, so good to see what you can achieve.
Cool, good to know more people.are getting into rtx ! 😊

Amazing Fabrice!
Thx !
Hi Fabrice, how do you open CMD command , which key do you touch for that?
Very nice ... please we want archviz Courses interior & exterior
Ok ! : )
@@FabriceBourrelly Thank you I am honored to learn from you
Thank you very much for this video. It's really great and very helpful.
Wow fantastic! You are a genious! Thanks for the tutorial!
Very nice laptop!
FABRICE! Glad to see you on something other than Epic classes! Always a pleasure to watch your videos! BTW, where did you get that awesome UE hoodie?
hey man ! great to see you here too ! : ) it's not a UE hoodie (I just happen to shoot the video after a class with my normal hoodie on)
Awww. Gotcha. You inspire me to do my videos, soon. LOL.
Appreciate it! Could you please also share with us some tips about RT GI? The noise from GI really makes dead.
ok, I will !
@@FabriceBourrelly Thank you so much!

Just bake using and turn off raytracing
Hi, are multiple gpus supported? What about ies lights? Are they ok with raytracing?
no multiple GPU as yet, unfortunately. IES lights are working really well though...

Reflections were too strong, I think. That's easy to turn down.
hi I WANT USE Lightmass Unreal Engine 4.26 Must get RTX 2060 or GTX 1660TI enough
You can use the traditional Lightmass with your GTX in 4.26 (it works on the CPU anyway so the GPU doesn't matter), just hit the "build" button.
Hey, great video. I really need to know how is datasmith running in UE 4.25. I cant seem to be able to install it on this version
love it man-!!!!
But you need to tweak the materials as well !
Explanation starts at 7:24
This is sexy, I was wondering. Could you animate emessive light materials.???
Great video FAB.
Thanks man ! Yes definitely !
...i'm sorry but...how do you open the Cmd bar??? :)
While using moveble lights how do you get GI? As far as I know (ım new though) they dont contribute GI. Thanx.
actually in Raytracing, they do. It's when you build the lightmass that the lights set on movable are omitted.
Hi, sir thanks for the video, would u mind answering me a question?
Do i have to get a RTX card to use raytracing in unreal engine?
Exactly Same Question!
For the best results, as RTX cores accelerate ray tracing performance.
Yes you do
@@FabriceBourrelly Sir, my specs are Rtx 2070s
64gb Ram
Ryzen 7 2700x
Will it be a lil more than Sufficient?
14:43 How did you change the material on the fly, without compiling the shader?
Probably because its a parameter.
Nice. How long does battery last when raytracing in UE?
Probably an hour if not minutes, laptops like these are made to be used on wall power, but able to move from place to place with ease.
Yes this one lasts surprisingly.long actually.so maybe 1 hour ? My "normal" laptop is indeed just minutes,.maybe 1/2 hour at the most!
Couldn't you do this before with Unreal and a good graphics card just by turning off baked lighting?
I think that might have been screen space GI. I tried it recently and it's not bad. No contest between proper raytracing GI though. I love the level of control. I'm working hard on getting UE4 integrated into our pipeline. Currently using 3DS Max and Vray.
Can we get a video on how to get Nvidia to send us a brand new laptop?
lol, unfortunately, they took it back ! :)
Looks great. Does this only work in 4.25?, i tried it in 4.24 and its really noisy?
I'm going to make a vid about the noise issue. but to answer your question, it pretty much the same in both 4.24 and 4.25
@@FabriceBourrelly Thanks Fabrice, look forward to the video
Cool! 😄
thank Jesus ! : )
Just a bit confuse when we use RT in UE4.. with those RT method, do we still need to bake?
RTX 3070: pfft 😂
