We´ve been doing some large resolution renderings using
mR on Maya 6.01 and had to update those scenes to Maya
6.5 since the "region" flags weren´t fully supported.
While fiddling with the problem on a 4GB Ram machine on
w2k/xp we noticed that in some cases loading the *temp*
file using the mR imf_display could be manually saved before
the entire process crashed. You just had to make sure you
displayed 100% - otherwise a scaled copy would be saved.
It´d contain every tile rendered and´d often just miss the
last tile...
I haven´ had to render large chunks of files in XSI/mr yet,
so I can´t comment on the proper use of the render flags
with batch but I´d suggest trying the region command and
looking for the tempbufferfile created during rendering.
It may also be that you simply can´t render from the commandline
using an XSI foundation and therefore the associcated flags
aren´t passed over correctly, seems XSI 5.1 FnD has some limitations
there that could led to this behaviour, for example, getting camera info
via the renderpass tab may throw a warning message that this isn´t
supported in the "MOD tool" version sometimes. ahem...
You did try the Render>Options>Format:Subregion options?
Basically, those should be hooked up to the appropriate region flags
automatically when rendering.
Cheers

i got this quite a while ago with another renderer (brazil). the
problem is that when a windows taks is using more thant 1.3 till 1.5
GB memory it gets instable and eventually crashes!
i always try to keep the scenes below 1.2gb for that matter.
so the funny side is that a computer with only 1gb ram wont suffer
from that. it just crawls because it swaps to disk but stays stable.
so in some cases less is more ;)
Wow. That's pretty interesting - if that's the case then I guess we
can only say thank you Microsoft!
