IRAY Photorealism?

It's really not Iray at that point, right? Man, this whole AI thing is really turning things upside down.

It is still Iray. AI is used as a post processing touchup, that's it. How much you want to keep of your Iray original image is up to you. But I often let things like backgrounds and fingers fall through to the original Iray render, keeping just the parts of the AI that improve the features I need it to. I'll put together a better demonstration later this week.

Iray is involved, of course. But the photorealism does not come from Iray. Not in the video example you showed anyway. Iray is only used to give the absolute basics to the AI which does the heavy lifting. I'd be hesitant to call this post processing.

Absolutely nothing wrong with that. I'm just saying this has little to do with Iray. Could use any other crap renderer. Probably even Filament or a screenshot of the viewport.

Sorry, but I have to disagree with you. Your gallery shows clear signs of relying heavily on Photoshop, particularly with one-click filters. If you believe in taking things to the next level, then it seems contradictory to have a gallery dominated by Photoshop filtering.

The AI actually enhances the Iray render in ways that go beyond what Photoshop filters can achieve. And the best part is, you can still go back and add post-processing in Photoshop if you want—I do it too! This can help fix issues like bad shading, specular highlights, and other Daz-related quirks. But at the end of the day, it's your art, and it's totally up to you how you want to refine it.

 

 

 

In Photoshop, when you're adding filters and maybe correct the exposure or things like that, you're trying to enhance the render. AI regenerates the whole image completely. Even if you force it to stay as close to the original as possible, it still technically generates a new image. Hence, to me at least, what you're seeing after that is not Iray. It is an AI-generated image that was made from an Iray render, and you could have used any other renderer, even probably a Filament image as mentioned. It's just a matter of prompting and settings.

An equivalent could be photoshopping a face from a real photo onto your render. Nobody would call this post processing. But it doesn't matter much, nobody cares in the end what was used as long as it looks good. But this is a thread about Iray photorealism so I feel it's at least worth pointing out that we are leaving that realm once AI image generation is involved.

It's still interesting though! Please don't take this the wrong way and by all means continue to show your results :)

I agree, in the end it's all about the results. I have been using Daz for a very long time now, and struggled with getting results to look as realistic as possible. So for me, I see this as a means to an end.

I wanted to much 
3 houres of rendering and not even 1% finished.
I just put too much stuff in this scene for inside and outside and now my 3060 12gb GPU is obviously at its limit.
Ghostlights don't help reducing render times, I've tried it.
But hey, it gives you an idea.

i dont think that scene shouldnt take more than 12GB vram. What is in the render frame looks like a fairly simple amount of geometry and textures, so i assume what is taking up vram is out of frame.

As to whether it is photoreal, I think it looks good because the assets are good quality, which is half the battle. I dont think this detracts from realism much, but i think the glossiness on the couch/sofa is perhaps too much for standard fabrics that you would expect for such furniture.
