dear list
i have a huge problem that keeps freaking out some kind…
im running into deep troubles with my rendering.
i have to render 5000 frames in 2k

i have win xp 64bit renderslaves and vista64 workstations and a debian-linux server and use (sadly) qube as rendermanager.
as first:
absolutely randomly and to anytime with anykind of pass or scene and any machine i get this error while rendering:

hmmmm, it seems that mentalray cant find the 1k .main file that was generated when it started to render, but when finished with rendering it looks like it cant find it anymore, even if it is present!
even strange to me is that the framebuffers are writen as the should! my it-men checked yesterday everything from back to forth and couldnd find any logfile etc that made us understand what happens here!!!!
please, i really hope that anybody can give me a help on this! im walking on the edge right now!

i’ve got the exact same problem.

all the passes where i activated Final Gathering avec giving me this error : Could not open [path of the file] for output: Could not create file. Does the target directory exist?

is there a solution ?
