We have a linux farm configuration where the worker servers read user-installed resources from a shared volume mounted to /home/tools/..., not from /usr/local/... This /home/tools/ directory is the only place we can install tools, including Maya, Mental Ray and Qube, e.g., /home/tools/pfx..., /home/tools/autodesk/..., /home/tools/mental/..., etc.
I have more or less figured out how to make Mental Ray work in a non-standard directory by modifying the paths in rayrc. How can I install and configure Qube to do the same?
