Print Resolution with Maya

Here is some info posted by a CG Talk member (sorry I forgot your name):

Also check out rendering the image in tiles and then reassembling after. Just make a batch of a 4-8 tiles for the commandline and use the commands(these are in the commandline render reference in the Render Utilities book):

xLeft -xl set X sub-region left pixel boundary of the final image
xRight -xr set X sub-region right pixel boundary of the final image
yLow -yl set Y sub-region low pixel boundary of the final image
yHigh -yh set Y sub-region high pixel boundary of the final image

You can split the image up between multiple machines or just render on one box. Also I would check out rendering on linux instead of windows. You get a 10-30% speed increase in rendering and it uses 1/4 the ram to render the same image as in windows.

very fine, I' ve never thought to render in tiles.
That will be the solution

My experience is that Maya only supports 4096x4096 ..

We hade problems rendering bigger images but the solution was the same as the above by rendering the images in tiles with the
subregion option.

I'm currently thinking of doing melscript that will present the user
with a GUI to these options.

- not really i had far bigger images rendered (something in the 8k´s) .. i am not even sure if there is a real limit to render image size..

when rendering in tiles, mem usage should not be a problem.. but for some huge sizes the amount of tiles may become one..

hint for that one:
muster from virtual vertex (www.vvertex.com)
this dist. renderer can split up single maya images in any wanted number of tiles (and now the clue): it assembles them for you as well...

so if you need it: just download it and go.
the unlicensed version allows 2 connected render clients only but that might even be better than assembling 20 tiles by hand :)

cheers

edit: maybe one more word to the tile rendering without using muster: be sure to render the tiles with an overlap of 3-5 pixels, because otherwise you will encounter discontinuity in anti aliasing..

Tanx everyone for the advices, it was a question which is very important when working in printing enviroments. I will try the vertex guy.

Hi

I made a very simple script that lets you render your image
in 4 tiles and then you can assemble them together in photoshop or whatever.

It's under "rendering & shading" ..

the script is called "SubRegionRender"

here's the link

Please don't hesitate to contact me if you have suggestions on
improvements.
