I noticed that for some reason lot's of jobs do not show preview images in rrControl anymore. But not all of them. And I can't really see why.
Most are exr. From Gaffer I have half exr with zip compression. Those show up fine.
But our Maya output showksnip_20260622-151324.png 
These are either exrs with zips compression or pngs. Both show the same result.

And our Nuke comps show this:

Usually no compression exrs or dwaa compression exrs.

All formats work if I click the view button to show the sequence in rrViewer. It's just the quick preview in rrControl that is not working.
This is rr 9.1.26a Linux., but I noticed this on 9.1.23 already.

Hi


The option Local Render Out could make a difference in addition to the file format and file size (afaik the rrClient has a lower memory limit for the image reader than rrViewer).

I will do some tests.
