Solaris: render to disk progress not visible for one frame

[anicg]

For one frame only, when I press Render to Disk on the USD Render ROP (for both Redshift and Karma), there is no progress visible on the screen (the usual pop up dialogue box with Mantra).

How do I know how far the render is and if it's actually working other than sneaking in the destination folder?

For a frame range, the progress bar does show up.

The render time for one frame cannot be predicted; hence the absence of a progress bar; just render a frame in the render view, and look at the ETA at the start, and compare it to that actual render time.

The progress bar for a frame range is linear in frames count, no global render time.

You should use the render in background button on the ROP. The percentage for a single frame will show up in the render scheduler dialog (which it should prompt to open when creating a background task). The scheduler is also available from the render menu at the top.
