run through of my working method for vray 2.4 sampling in arch vis scenes.

[Dariusz Makowski (Dadal)]

I havent had 17h arch viz render since 2008 I wonder what went wrong here hehe

[joconnell]

17 hours for that is madness. Count me in as one who'd love to have a go.

Solid process though - just much bigger numbers involved than i'm used to

Yeah, to be fair it was a jump to really unoptimized settings on the materials so quite a dramatic change!

[joconnell]

Yes, definitely. I was rendering a similar scene today and it took no more than 1h for perfect results.

I'll pop you a scene to your chaos email, of course now I'm crapping myself incase I left anything embarrassingly stupid turned on

with the script you mentioned

Awesome work on the video John! Thanks for taking the time to put this together!

[Dariusz Makowski (Dadal)]

Can you upload the files scene so others can have a go at it too maybe?

[vlado]

It's nasty alright - Vlado would it be worth sending the file across for profiling?

Also - worth noting that one of the last things I did was sort some intersection on the geometry (which took down our time by about 20%), since the scene is largely glossy refractions and raytracing, a large portion of that 17 hours was probably dealing with co-planer faces so it should have been a large portion less.

Also, you mentioned using a render farm. With the image, which had a pretty low resolution, what were your PC specs? Some might say that 3 1/2 hours is huge for a small, low resolution image, and horrific on a render farm.

I was going to say that; 17h for the original image at this resolution seems a bit high, no matter what settings.

Personally, I would be totally happy with the quality and render time, but I have heard images like that should take minutes and not hours.

I enjoyed the video. I like that your thinking isn't so binary. Sometimes people take things literately, and from other recent discussions might have thought brute force is the only way we should be working, which isn't totally accurate. But, having said that, have you tried brute force?

Very nice John, just downloading to watch with excitement. I wonder, will you update soon with Vray 3?

[glorybound]

can you share your script for applying subdivs per blurry values?

[rivoli]

will have to properly watch it, as I barely had to time to skip through now, but it's already extremely fascinating to see how very good artists like you work. great effort and thanks a bunch for taking the time and sharing.
