what size is good size for large printings?

[Dariusz Makowski (Dadal)]

Heya

Well I rendered it on one 2x Xeon E 5530 not overclocked back then and 24 gb ram... It took around 10h to render it. At 10k+ resolutions AA changes and a lot things works differently... Atm I'm rendering car layers it takes 10min per 10k render so its all down to how well you can set up render...

I guess it's totally dependent on what you are rendering. A lot of displacement, and high poly trees, are resource hogs.

How are you guys rendering such large graphics? I mean, how many machines, and how long?

I'll be honest, when I see most people's render times on the forum my jaw falls through the table. 99% of the time the minimum we render things is 8'000 at the longest edge and I would be extremely worried if the final render, including any channels/effects passes took more that 8 hours.

In terms of hardware there are two of us here, we have 5 identical machines (i7 x 980 3.33GHz, 24 GB ram), two machines each and one spare running as a license server and render slave. We try to render things overnight if we can but if not we'll divide our renders between those 5.

I now trying to put one through BB at 4096X2458, on 6 workstations, and it going to take 2 days.

I actually cannot even imagine having to wait that long for a render that size. Even if it had displacement, caustics...etc. That seems insane to me. What power are the workstations you have rendering it?

[glorybound]

I have 6 i7's with 12Gb of ram per machines. I think they are clocked at, or around, 3HGz

So, how does MAX, or Photoshop interpret LPI?

they don't..
it's nothing to do with Max or Photoshop - it's what happens when an image gets halftoned at the printing works
(or at the digital print stage)

in fact Max doesn't really use dpi either - it just uses pixels and outputs an 'x' number of pixels wide file.. whether its 2dpi or 200dpi it's an identical image
- you just might need to scale it differently in your page layout program

[sorry - I just think it's important people understand pixels, dpi and lpi]

Wow. I realise this might not be practical but if you have an example of a scene that takes 2 days to render across those spec machines I'd love to take a look at it.

[glorybound]

I'll post the one I'm working on now. Please, give me about an hour.

AJ Jefferies.... I just PM's you the scene. Any feedback would be wonderful!

Here is the scene I'm sending you

[AJ Jefferies]

Thanks Bobby - will take a look!

[Morne]

Thanks Bobby - will take a look!

and let us know what you find please...

I cleaned all my computers, and I'm trying this again. Is 7200x10800 a reasonable goal? I'm using DR and BB, on the previously mentioned hardware. I also figured out that you only use BB on the main workstation, while using BB, and you don't actually hit render (3DS MAX Design 2013). So I cut the render up in 20 slices, using BB on my main machine, and I'm using DR with 5 slaves. Once I send it to BB, I close MAX to free up that memory.

[glorybound]

Just a follow up... Everything seems to be working for me now. I'm not sure why, but using BB as described above, works well. Maybe, my issue, was resources. All my slaves are jumping in, and all my machines are no longer grinding to a halt. Now, having said that, things might change on a dime.
