Let me throw some suggestions at you. I fought with a similar situation and
spent weeks trying to nail it down. In my case, every third or fourth frame
was trashed. There would be a bad byte that would scramble the entire image.
What – I – was doing was Net rendering on 3 machines and saving TGA files to a
common server. Nearly EVERY file generated on one machine was corrupt. So, I
rendered to a local drive on that machine to see if it made a difference. The
files looked good, so I copied them to the server — and EVERY one from that
machine was now corrupted on the server, but GOOD on the local drive.
After doing file comparisons, and copying files by floppy disk, and so on and
so on and so on… We discovered that for some bizarre reason, network copy
operations were subtracting 02h from every byte!!??!!
To make a long story short, we changed our Ethernet card, and everything ran
flawlessly again.
To see if yours is a similar problem to mine, check your net render log and see
if bad frames are coming from one particular machine. Are they always saved to
a common server? Do you always VIEW them from a particular machine? Work
completely LOCAL on each machine, and see if the problem still occurs.
Hope this helps.
