Dolphin thumbnail fail
Comment 2 Nate Graham 2022-06-28 16:22:01 UTC
Can confirm. Probably the file format changed enough for the thumbnailer to start failing.
Comment 3 machaquiro 2023-05-10 09:23:35 UTC
Still no preview with recent Blender 3.5.1 and latest kio-extras 23.04.
Comment 4 Kloud 2025-12-09 07:37:27 UTC
Can confirm
Comment 5 Kloud 2025-12-13 12:54:03 UTC
Blender ships its own thumbnailer. This can be fixed by adding this

```
[Thumbnailer Entry]
TryExec=blender-thumbnailer
Exec=blender-thumbnailer %u %o
MimeType=application/x-blender;
```

to ~/.local/share/thumbnailers/blender.thumbnailer
