This new version of the Blender Cloud add-on introduces a small new feature for Flamenco. It is now possible to override the render output directory on a per-job basis. Very useful if you want to quickly render something to a specific directory without changing your overall project settings. This also allows rendering the same file in different render jobs with different output directories!
Just click the pencil button to enable the override. To return to the default project setting, click the cross.
