When sending a USD render job to Hqueue, I'm having a problem when the USD is generated by Windows and the render happens on a Linux machine. I think the output path gets evaluated at the USD creation step and the Linux render fails. Any ideas on how to circumvent this.

Using $HQROOT on the output image path/field in the karma LOP. If it all runs on either OS it works. It's when mixing that it doesn't.

Is there anyway to send a job that doesn't separate USD creation and rendering?

Using the "Override Image Output" field in the USD Render LOP doesn't fix this.

Looking at the command that runs on Linux I see the input path still has the $HQROOT while the output path has been evaluated (on the windows machine to "G:") ...
