Mental Ray Newbie Question: Memory/Performance
on Sep 6, 2007 at 1:59:55 pm

Hi folks,

I just began using MR within the last week or so and was able to render out my scene in a fairly high resolution 9"x9"x300dpi. Anyway, now I'm being asked to make a poster-sized hi-res rendering of this scene so I need to bump up the size to about 30"x30"x300dpi. When I tried rendering at this size, it failed. I am using a couple of Targa texture maps in the file which I'm not sure that MR likes.

I'm running Maya 8.5 on Windows XP with 2.4 GHz processor, 2 GB RAM and 80 GB of free hard disk space.

I am buying some Mental Ray tutorials (which I haven't received yet) but in the meantime, can anyone point me in a good direction on this?

Thank you,

- Tom

Looks like I found a workaround that'll work. I'm using mr_tile_render 1.0.0 to break up the high-res rendering into 64 smaller tiles (8x8) and then using a batch command to call the free imagemagick software to stitch it back together. It's a good idea to try this out with a low-res render first, just to make sure you got it working.

Cool!
