Render at scale 1:1 ??

[sygboe]

Hi,

 

i'm producing artwork for some hoarding to hide a building site.

 

The hoarding will be printed in full colour onto plywood (new technology I think).

I have to produce 1:1 scale artwork that is a realistic rendering of part of the building, so as the building work has less impact for weddings held there.

The printers will scale the file to half the size then blow it up, but the final result will be actual size.

 

The hoarding is 7m x 4m

 

I have high res pics of the stonework to use, but have to make doors and windows in 3D to the largest possible scale, as you can walk right up to it.

The question is, how do i make an image that big? or is it in bits to join together in Illustrator (which is what i'm doing with the stones).

There's a script to split render jobs into different sections/jobs.

You then put them together in Photoshop.

I've rendered some really huge scenes.

Not in front of my normal computer, but there is a post here.

or you could google "master zaps mental ray tips" or something like that... the script can be found on his blog...

 

works really well, we have used it for a similar situation with hoarding.

 

edit: that is unless you are using something other than mental ray...

Vray has an excellent proprietary file format, *.vrimg, that will allow you to render practically any size of image you want.

a normal frame buffer will try to load the whole rendering into your ram, while rendering, so you should disble the MAx and Vray frame buffer and only use the preview. And render to the vrimg format.

Vrimg is like a big box that Vray puts its rendered buckets into once they're done, so that they don't use up your ram "space".

i hope i'm making myself clear here. otherwise try googling vrimg, and check out the vray user forum.

 

Once you've rendered, you need to convert the vrimg file to OpenExr, form where you can open it in any image editing application. There's a bit of nudging around with the command line editor while extracting the different channels, but you'll learn to love it. A *.bat file will help you.

good luck.
