Settings defaults

[cryham]

Hi. Versions before recently, had export settings saved for whole Blender I think. I had set them once and any new blend scene with model had it all set up. Recent versions require setting it every time I open a blend file. Seems they are saved per file now. How do I set some defaults? So I don't have to click and set it up all over again for every model.

Well, thats strange.

There was a bug in the way that settings were being saved and what happened to me with previous versions was that the settings were being reset every time.

I was not aware that there might be something per blend file.

Are you using linux?

How did you install Blender and blender2ogre?

[cryham]

Yes I'm on Debian 12. I got Blender 4.1.0 just by unpacking it into a folder from here I think. Unpacked blender2ogre by downloading a zip from github and following readme. Ok right, it's not saved in file. Just kept in opened Blender.

[sercero]

Are you saying that the settings reset every time you open Blender?

[cryham]

Yes, exactly.

[sercero]

Does the log say something when you first start Blender?

OgreMeshTool.log is written in Ogre-Next build path: /home/ch/_sr/Ogre/ogre-next/build/Release/bin/OgreMeshTool.log and has nothing suspicious:

Hmm what attributes should this have: /home/ch/.config/blender/4.1/config/scripts/io_ogre.pickle because I see 644. Same as I had for Blender 3.6.

[sercero]

No, the log we need here is the blender2ogre log.

I'm suprised you have the io_ogre.pickle picke file because now the file were the settings are being saved is a JSON file. That file might be from a previous blender2ogre installation.

So there might have been an issue creating the file for the new settings.

Do you run Blender from the CLI?

I want to see the Blender logs when you start it and when you export (the CLI logs).

When the export dialog shows is when the options are loaded and when the exporting process is finished the options are saved.

There might be I/O errors with permissions in the log.

[cryham]

Okay, but I saw io_ogre.pickle recreated again after I deleted it. Where is blender2ogre log? Sorry I forgot. So I ran Blender in CLI, loaded a palm, exported and closed.

Ah okay. I got the latest version installed now 0.9.0 and did that again. It seems to save settings now. Strangely sometimes I don't have export .log in same dir as .mesh
