Hi William. I wrote to your Instagram account but you didn't reply. I need your help. My project is big and with your help the result could be very good.

@WilliamFaucher 2 года назад

@@esrarchitecture4136 Hey man, I get a lot a messages on IG, and it would be a full-time job to get back to everyone so I apologize. I really don't have enough time in my day to answer everyones questions unfortunately! It's nothing personal!

@esrarchitecture4136 2 года назад

@@WilliamFaucher I understand you bro, time is our problem. I have to animate this project very nicely. I need a little help with this. The project is an interior design animation of a large classical building. My video card is GTX 1080ti and I passed the project unreal, the details are very bad and blurry. I used ue5. Which video of you should I watch for lighting and upscaling? This project is very important for me, even for my business life. I hope you can understand me bro.

@PiyushYankee 2 года назад

@@esrarchitecture4136 I suggest you should use Unreal 4.27 with raytracing, that is what saved my project too, I have been using UE5 to quickly set up lighting but there were lots of flickering issues in an animated video, I think because of screen space Gi and reflections. I have a gtx 1060 6gb but All I need was rendered frame and It worked great apart from a few crashes but Still I get to Finish my project in Time.

I was waiting for this video, William. This feature inside the engine is absolutely relevant for stills renders as a full package product with realtime content. Cheers, William!

Just wanted to say that out of all the tutorials and guides online, I find yours the most helpful. You give practical, technical and artistic advice all in one. Also really nice that it's from a VFX point of view since that's my industry as well.

@WilliamFaucher 2 года назад

I'm still alive! Real life just gets in the way sometimes :)

@stephenforsyth7883 2 года назад

I'm really excited about this move because it just simplifies your life as a 3d artist so much, once it's feature complete you're basically free to build your library of resources and personal pipeline entirely around UE and lose nothing for it. Even just being able to render out stills path traced but render fast videos in real time opens up many options.

@bertcraft 2 года назад

@FilmCore 2 года назад

Another great tutorial! Thank you so much, always wondered what tf to do with the Path tracer! Like you said, I'll probably use it to compare the lighting for my real time renders! :D

@WilliamFaucher 2 года назад

Yeah it's great for comparing! But also amazing for final-pixel renders if you can afford the wait times.

@FilmCore 2 года назад

@@WilliamFaucher Yeah the final results look absolutely amazing, but i moved to Unreal to avoid the long render times haha. Maybe one day for a huge project when I have a lot of time I can go back to path tracers to get that supreme quality. Keep up the vids man! They're a lot of help!

@WilliamFaucher 2 года назад

@@FilmCore Yeah I don't see this replacing the realtime stuff, it's just icing on the cake, a nice feature to have if you need it. It makes Unreal a pretty well-rounded package now!

@user-tk5jx4ih4g 2 года назад

When i watched the intro i didn't notice this wasn't real for quite some time. The only thing that gave it away where the figures after some time.. They looked a bit to perfect and clean. Next to the rather rough table the lack of dust on the figures broke it after a while I think. But the wood looked so damn real i felt conflicted on what i was seeing. Incredible to see what's possible in todays time already. I have never seen such a realistic render of wood. The camera shake also helped to sell the illusion. Fantastic work.

@WilliamFaucher 2 года назад

Thank you so much for the kind words, I really appreciate it! And also thanks for the constructive feedback, I totally agree about the dust, would have been cool to add dust and stuff on them but alas, we don't always have the time on our hands!
