Changes have been made to the Maya Heads Up Display (HUD) Evaluation Manager status messages to better reflect the condition of the Evaluation Manager (EM).
The previous "Rebuild Required", then "Ready" (but still requiring partitioning) status messaging was unclear if the EM was performing Parallel evaluation.
The new status messaging is now Rebuild Required, then Built, followed by Ready, states that depict each stage of the Evaluation Graph as it is unbuilt, built, and partitioned.
To display this information on the Viewport, go to and choose the Evaluation option.
