We're testing those too but the problem with sgi's is that they aren't
supported by PS without plugins. I have an sgi importer plugin on my system
but I guess it is buggy or has issues. I personally haven't done any testing
of that plugin other than open an sgi image.

why don't you use 16-bit SGI? It's the most compatible format.

Conversation: 16bit tiffs
Subject: Re: 16bit tiffs
Haha, HEY it showed up! I sent this yesterday and it didn't get posted to
the list at all. Unless I'm not recieving my own posts until someone replies
to one of them. It seems like that's when they pop up.
Anyway, I called Soft today and they said it's a bug that's going to be
fixed in the next release. The workaround is what Luc-Eric said. Pipe it
through the FX Tree. Which imo sucks if you have lots of passes.
Btw, we've been using 8bit sgi's for a while but our flame guys want to step
things up to 16 then output at 10 from flame. File format is the biggest
issue at the moment. Once this gets fixed I think we'll be switching to
16bit tiffs.
Thanks for the input though guys.

no, that was the reverse question, loading tiff, this is about the
tiffs that are written.
16-bit tiff output is broken in Mental Ray. Fixed build is not publically
available. Use .sgi files instead, or fix the tiffs by going through the
never-has-these-kinds-of-problems fxtree..
