Just had an issue, for the first time in years, where -some- of the images, the images (logos etc.) in overlays, and the titles (lower thirds) all came up blank and offline. The camera inputs and .mp4 pre-roll loops remained OK. We were about to do a broadcast, so I made the main video live, and then created new inputs and re-did the couple of overlays I needed on-the-fly.

Still scratching my head about how this happened. I had quickly tried restarting vMix and loading the most recently-saved .vmix and .zip saved preset files, but no luck.

None of the file locations had changed, and the lower thirds were in their default locations. Same computer, no intentional changes to the boot drive (where -everything- lives) etc.

vMix 4k (licensed), 27.0.0.72 x64, Windows 10 Pro, fully patched.

I'll be doing a post-mortem on this, and see if any previous saved files have the same issue, but any ideas?

SOLVED: OK simply wacky. None of the file paths to the images changed, and certainly not to the titles, as they were left at defaults - and as noted, EVERYTHING was on the native C drive. But the problem was solved by rebooting the PC. All works as before - older .vmix and .zip files open just fine.

Go figure. Even though the PC is a fast one, and the boot drive is an SSD, a broadcast had started, so I worked with what I had going, and I didn't need anything too fancy from vMix. The reboot, however, was the fix.

That's wackier than my issue. I have no clue.
