You simply can't. Network path resolution is completely different between both operating systems which relates to how the generally mount external resources within their normal file tree (Mac) vs. as independent virtual devices (PC). Nothing you can change or influence. You could use specific Mac emulation software on the PC end, though, and exclusively run the server in Mac mode. The emulation would then take care to remap file paths in a Mac-friendly way which would take care of your issue, presumably.
thanks for the answer, what a downer though, so much for my drop and forget render farm....
Hey, sorry Mylenium, but this statement is not true. I was almost convinced to give up after reading this, but I managed to make a working conversion tool shortly after.
This is the method in After Effects, I am pretty sure that it can work in the rest of the adobe suite as well.
All you need to do to get the paths to update to windows format is to:
1. Select "Save as xml" and save an .aepx.
2. Open the .aepx in text edit.
3. Perform a find for "/Volumes" and replace with "//<MountPointOnThePC>" (for example I have the drive as a network drive on the pc so I swap the <MountPointOnThePC> to the name of my mac as that is the path on the pc machine)
4. Perform another find for "MacPOSIX" and replace with "Win"
5. Save your file and you will be able to open in on a pc with all the files online.
Disclaimer, I built this to work on my set up using a mac server and a pc render farm for after effects. Please back up your projects before opening them and editing them.
Hope this helps anyone else trying to do the same.
