Images going to local folder

Okay, so I have posted a few times here and I appreciate the feedback. I have muster working with the render nodes, there is just one catch.

Here is the setup, Muster runs on a PC and the render nodes are OSX 10.5.7.

The main need it for the render nodes to handle Mental Ray.

I was choosing “mr – single file” as the engine and point to the project directory, click “submit” and getting hte following error:
error 211010: failed to create 128-byte stub image images/prestige_close.009.tga: No such file or directory
IMG 0.2 error 101003: images/example.001.tga: can’t create file (No such file or directory)
IMG 0.2 fatal: file error, exiting.
IMG 0.2 fatal: file error, exiting.
Rendering complete.

[MUSTER]Process terminated with the following exit code: 0

So, I created a folder on the render nodes in the root called /images and the .tga files all output there. Each chunk on each render node in it’s own images folder. I don’t know how to get them all to output back to the server.

There is no option when choosing the “mr – single file” engine to select an output directory for images. I suspect it is a problem with the cross platform config we have (Windows and OSX), but I am hoping someone has a workaround.

Thanks in advance and I will be checking daily, so if more info is needed, let me know.
