Blender JPEG vs JPG

General
1

Hello,

trying to render in Blender as jpegs.

getting this error when publishing:

* `ValidateExpectedFiles` does a string-exact filename comparison
* Expected: `...Beauty1001.jpeg`
* Actual on disk: `...Beauty1001.jpg`

Am I right to believe that Blender just messed up by using “JPEG” in the file extension list but have “.jpg” as extension when rendering?

Is this a known thing or just me?

Thanks!

I wonder if this is a blender thing.

I can see in Supported Graphics Formats - Blender 5.1 Manual that both .jpg and .jpeg are acceptable/expected for JPEG format.

I’m not sure if I trust gemini but it says:

File Extensions: Leave the Extensions checkbox ticked. Blender will automatically append .jpg to the end of your rendered file names.

Blender writes jpeg but AYON expects jpg - should we change that somehow?
Isn’t that the issue of why it isn’t publishing?

AYON expects .jpg is true.

I kept snooping around and found this. That could be it? That would be why it expects jpeg instead of jpg?

I believe so - could you make a PR? We’d happily review it to confirm the changes.
