Indeed. I literally spent 6 hours deleting cameras, removing any animation in the scene (thinking I might have some hidden overlap), resetting up the whole thing, then making and rendering the test. I could walk through the PNG files and see that they should sequence correctly, but just couldnt understand why they didnt when I used the viewer in the sequencer. The issue would be entirely hidden if the renders werent pumping out in half a second. The “date modified” sorting couldnt tell the correct order because the renders were happening so quickly. I think that meant it was putting them in a bit of a random order for those that happened in the same minute. If my system had taken longer to render each one, it wouldnt have shown up. I would have reformatted the hardrive and reloaded my operating system and never figured it out!
