rendering, but write fails?

[ironhalo]

hey everyone, i posted this in cgtalk, but no one seems to know whats up so far. im rendering on a render farm, but the problem still occurs locally. basically, the render log says taht the render completes. but, it fails to write the rendered file properly. the resulting image is just 1k and obviously wont open. heres what the log said for the error.

PHEN 0.0 progr: writing image file Z:/00000_mentalRay_vein_flythrough/shot-01/vein_rly/vein.0033.tif (frame 33)
IMG 0.0 error 101003: ...000_mentalRay_vein_flythrough/shot-01/vein_rly/vein.0033.tif: can't create file (The device does not recognize the command.)
Error: (mental ray) : ...000_mentalRay_vein_flythrough/shot-01/vein_rly/vein.0033.tif: can't create file (The device does not recognize the command.)

thanks!

I think you should render to newtwork path like //pc name/dir/map.tif so all render nodes could access that path. And that dir must be shared with write enabled. I think so ;)

someone replied!! we're working off mapped network drives, and all the sharing is correct. whats weird is this error happens intermittently, like less than a quarter of the time.. maya ended up getting reinstalled on all the nodes, so i need to test it again.

personaly, i'd sugest to write output images localy.
could it be network bandwith issue?

[ironhalo]

unfortunately locally writing isnt an option either :( all our work is done off a server hosting all our files. the render farm works on the same principle. we're on dual nic gigabits, the only thing we've decided to be a factor so far is somehow the file is getting lost in the network...?

FIXED!!!

as it turned out, the problem was the render directory i was using. a co worker found it in the muster help files.. apparently muster and mental ray require you to render to the default render directories set up for you by maya. i was rendering to a second drive, let alone the same directory. i tried it out, and i had 100% reliability!
