Avarege viz render time ?

[Dariusz Makowski (Dadal)]

Heya

Something I wonder but what are your guys average render times?

2000x2000 res +/-
Interior
Exterior + forest
How many computers
How many render elements

Can any1 share theirs statistics?

my latest, the ELK fountain, rendered in 2 hours. I have 1 - i7 with 32Gb of RAM and 5 - i7's with 24Gb Ram. I use around 5 elements. The scene had about 2000 trees, 1000 bushes, and lots of displacement. It was a 3200 x 1600 render.

Ooooh I dont think there is an average
At the one site I'm at we have 7 X i7 3930K 32GB ram (no overclocking) rendering with DR

Interiors at 4K between 2.5 hours to 5 hours
Exteriors with foliage etc at 4K around 1 to 4 hours
20 Render Elements

Its difficult to say I guess it depends on the type of projects and workflow

[AlexP]

It varies wildly,

But interiors 2000x2000 maybe 20mins or so. Hour max for hi res.
Exteriors, depends really

12 render nodes - 336 buckets

Not many elements.

Lovely thanks for info ! I'm getting similar results. I was just wondering if I'm in good/back bracked as Viz for me newer was really that important subject only research.

Thanks all for ur info, any more always welcome. Will be nice to know what awaits me in viz industry o.O

5hours total on the day shot at 4k, if you include all the irmaps & fog passes. actual base render was 2 hours and as clean as you get.

How many machines? - do I even want to know?

[Neilg]

A single i7

A single i7

And you just crashed my brain. Yea then if I'm getting 4h at 2k then I'm definitely doing something wrong Thanks for info

The most important thing is reflection depth. change everything to one. if something has a glossiness of around .7/8 with objects visible in the reflection switch it to 2, and higher switch it to 3. glass is the only thing that needs to be higher (and if there's any amount of glass in my scenes i switch it off entirely and do it as a separate fully reflective pass to add back in post)
If you pre calc the irradiance map/LC with glossy effects switched off and reflection depth on 1 (sometimes i'll use the vmc to switch reflections off entirely) it'll speed it up to a ridiculous degree. I use most of that speed boost to increase the quality significantly though.

good advice. I started turning reflection depth off on my trees and bushes, which is the only way to go.

I wouldn't switch it off completley, it's a big change to the look of the leaves because the ones at the top pick up the colors from the sky and it gives more variation in color throughout

[glorybound]

well, I mean I set it to 1.

I turn off trace relfections all together on trees. Saves heaps of time. Will def try adjusting reflection depth and do some testing. Also interpolating the reflections of super blurry stuff like concrete and bluestone can be a big time saver. Im rendering out 5k in 3 hours on a dual xeon workstation and it's a super clean render.

I tend to use interpolation on tress and nature as I only need a variation in reflection rather than something accurate.
