Hello Guys.
So I started to play with Iray. I'm rendering a 30 seconds of facial animation made with iphone X and live face, speedtrees . I 'll post here the result tonight. It 'll be finished this evening. I just post one of images here.
What I can say is : it's fantastic. As you see on my profile, my machine is humble and yes, it takes too much time. But the result is there. I think that I won't use iray for everything, just for some large facial animation scene. And I will show you water rendered in Iray (but I need a time, that's the BIG BIG problem)

Okay, here we are. The workflow :
character made with facegen, => daz G8=>CC3
Animation : Live face and iphone X
Standalone rendering with max iterations 300 - max time 100s - rendering time = 16 hours
I started the rendering yesterday at 11PM , I went to bed, wake up, go to work, go back home, open my computer, It's finished.

I'm too old to Iray.
I know that sounds like a hip-hop song or something but at 16 hours for 34 seconds of video, I'll be dead before I can
render one of my videos. It looked fine but not so fine that it's worth the time, even overnight.
Let's see, a rough calculation brings me to 564 hours of rendering for a 20 min video. Check my math but it looks like it
would take 23+ straight days of rendering to finish a 20 min video.. My computer just looked at me and "Huh uh, not on this think box, it's not."
[God, I hope my math doesn't embarrass me. :P ]
Nice work though man. It looks very good.
:cool: pete

Thank you Pete. I totally agree with you. That's why I said I can't render all my scenes with Iray, I'll choose some epic scenes, just few because my machine could not follow

So I did another video, the same, but rendered in native iclone with IBL and GI quickly made, not worked a lot
Rendering time is 4mn20s against 16 hours with iray, the result is not too bad, without SSS but not bad

Nice test Rama,
I do think that if a bit more time and better lighting were put into the iclone render it would be almost as good as the iray render, and now with the new HQ 3d scan heads, things will be much better as it seems it's the avatar faces that seem to determine the perceived quality of a project.
It will be interesting to see how iray is used in iclone but at the moment iray seems too slow for animation even on some of the BEAST machines forum members have.

That’s what it’s starting to look like. We haven’t seen a really complex scene with a bunch of lights and props SSS etc. Iray May be great for small clips or stills of certain shots. We’ll need workarounds otherwise. There were a few guys on the forum saying pretty much this will be a waste for animation. I wouldn’t call it a total waste, but it may be pretty rough to pull off for a larger project and a modest machine. I’ll do some tests once I finally get some spare time under my belt.

They both look good but iray is not really an animation engine.

It would be good for tight close up facial shots. Look at a movie and see just how long the takes on people's faces (or any individual takes are for that matter) -- they are usually only 2-4 seconds each. So an iray animation could make for very compelling use in key moments, but it would need to be sparingly used in order to actually finish the movie lol.

Hello Guys, being discouraged by Iray for long, or even medium scenes, I've worked a lot with GI and IBL and LUT for my project, and I confirm, I'll use Iray only for very very short scenes because even without Iray, Iclone does a very very good job
These renders are NOT Iray

Hey Charly, I get what you're saying about the 'time' aspect, but I do like your Iray version better than the standard iClone. I'm not saying Iray's necessarily 'worth' all the extra machine time, but it's still a better result imo .... Nice animation!

Thank you Steeve. Yeah, Iray render is better. But why I told I liked the result more than Iray, this short part of the scene (without camera movements, without facial animation etc...) is rendered in less than one minute, and with Iray, It'll take hours and hours. But the difference of quality is not huge but the difference of TIME is enormous :)

Yes, I guess it sort of goes something like this (subjectively):
Quality: Time taken:
iClone 50 x1
Iray 75 x20 (or more)
And that's probably being generous about Iray's 'time' ....

exactly, and for me the choice is made, I'll tell 60 vs 75 for quality :satisfied:

I wish I remembered the render times that I achieved almost 20 years ago when I started with 3D Studio Max 2.5. But I do know it was rendering overnight for a short segment and that was for relatively low resolution.
So I don't really expect super-fast for getting the look I'm after.

Guys, Steeve is absolutely right, I rendered the same scene with 40 iterations and the render time passed from 16 hours to 6 hours, and it changes all things, I'll post here one video with all animations, props, water and so , the quality is great (with 40 iterations)

Guys, the difference between iclone renders and iray renders can be worlds apart, the problem i see is that you are just letting the auto convert do all the work and while it works great and it is way easier than the Indigo one, you still need to tweak shaders and lights to push to the next level.
I hope to be able to do the iray webinar by the end of this month , it will be in two parts. the first one will cover the UI and materials, and the second part will be lights, environment effects, and animation. And if time allow compositing with render passes.
Stay tuned.
Cheers,
Stuckon3d

We are all still searching and there's no doubt, Iray can push the level so high but the problem is : it push the time's level so high too :) that's why "amateurs" like Steeve and me exchange our experiences. Here, we are talking about time, So this webinar will be welcome especially if it reduces the rendering time.

I'll be looking for this glad to hear!

Master, try to make a short that is quite complex, it is possible that for the next century this finished

I don't know how far you call "next level" of animation (I don't talk about a still images, I've seen tons of them, I'm talking of Iray animation who does not take 20 hours for 15s of video)
But with the advise of Steeve and some personal "adjustements", this 17 s of video was rendered in 3 hours. I think that I don't expect better with my humble machine but this level of quality is okay for what I do. Now, I'll be focusing in my storyboard and will continue to work with shaders and lighting as you told. And I hope a solution will be found for the flickering problem :P flickering appears with speed movements so for speeds movements I'll stil using iclone render

Looks not bad at all! The water comes up nice :)
Good to see that there is hope for us 1070 guys ;)

Thank you 3Dtester, but we really need realflow :-) .

I TOTALLY AGREE. IRAY IS USULESS TO RENDER ANIMATIONS. EVEN IF YOU HAVE A POWEFULL MACHINE. FORGET IT.

Yes, I definitely choosed nativ render, playing with GI , IBL and AO and the result is so good considering the time rendering. Since now, I didn't see a good, long animation with Iray, yes it's very good for very short animations and still images but not for movie
