Blender job submission overview
It is always important to use relative pathing for any resources needed for the render that exist outside of the scene file. The easiest way to accomplish this in Blender is to convert all links to relative pathing prior to submitting it to us. You can do this by going to File > External Data > Make All Paths Relative.
Scene files utilizing Cycles GPU rendering will be detected during the analysis phase and scheduled on our GPU farm. All other render engines will be scheduled on our CPU farm, including Cycles when GPU rendering is not defined in the scene file.
Finally, please insure your scene file output size is set to 100%. The default of 50% will not produce the results you expect when you submit the job to us.
