Sentry Crash Report:

Description Xelis 2010-07-28 17:18:38 UTC

Version:           unspecified (using KDE 4.4.2) 
OS:                Linux

New Blender 2.5 has now the ability to show thumbnails of the scene in file manager:

http://durian.blender.org/development/system-benchmarks/

The developers say it follows FreeDesktop standards to generate thumbnails as you can read over there
http://durian.blender.org/development/system-benchmarks/#comment-14695

and actually Nautilus in Gnome can properly show scene thumbnail as seen here
http://durian.blender.org/wp-content/uploads/2010/07/scene_52b_files.png

Dolphin instead doesn't seem able to show them, all you can see is default icon with no thumbnail at all.


Reproducible: Always

Steps to Reproduce:
Create a scene with Blender, save it and navigate with Dolphin to the folder of your saved scene, you can't see thumbnail but only default icon.

Actual Results:  
You can't see thumbnail in dolphin.

Expected Results:  
If Dolphin follow freedesktop standard it should show Blender thumbnail.

Thanks for the suggestion, but Dolphin is not responsible for creating the previews itself. Someone would need to write a blender-thumbnail-plugin for KDE.

Comment 2 Xelis 2012-05-17 09:18:31 UTC

Hi Peter, in my opinion it's blender that create the thumbnails, nautilus only shows them correctly as them were images, the thumbnails are incorporated yet in the .blend files by blender itself.

Comment 3 Mathias Dietrich 2013-08-29 09:35:27 UTC

Hi,
fyi, someone already created a Blender Preview plugin but I don't know if it is still working.

More info here:
https://github.com/kayosiii/kde-thumbnailer-blender
and here:

If someone tests this and it's working, it can make it's way into KDE if you find a maintainer for it.
Then contact dolphin-devel with the code and post it on the reviewboard.

I am the author of that thumbnailer. What is the best way to get in contact with the Dolphin devs. The IRC seems general to all of KDE and the mailing list doesn't look like it has any posts.

Comment 5 Christoph Feck 2015-04-29 09:47:50 UTC

Danni, you can find Dolphin developers at the kfm-devel mailing list.
