Hey all.
I'm trying to submit (with python) a job to deadline that will export vray
scene to a specified location.
the next step will be to send another job with dependency to the previous
job that will render those vray scenes files with vray standalone nodes.
i managed to send a job with the right parameters that look similar to the
job submitted from deadline submitter but it doesn't seems to to take the
output path for the vray scene from the parameter, instead it take the path
from the render settings field.
sometimes it renders instead of exporting vray scene files, not sure why.
in addition it doesn't export vray scene file foe each render layers if the
maya scene contains it (i'm using render layer legacy)
i'm using and old script i have to send jobs to deadline.
in order to send vray scene export jon i cahnge the 'Renderer' to
'vrayExport' and specifiy the parameter 'VRayExportFile'
this is the job parameters:

maybe there is a better way to do it..
