Black Thumbnails

ullmeo

The thumbnails of files saved from the latest version are completely black.

Apparently, if you close the app with the autosave setting, you get a completely black thumbnail.

Thanks for letting me know about this, it kind of makes sense that this started happening as some code related to thumbnail generation was changed in this release.

I seem to be having a hard time triggering this issue, is there a way that you close the app that could be causing this?

The screenshot seems to be from iPhone, I tried it on iPhone12 + iOS14, iPad Pro 2018 + iPadOS13, iPad Pro 2020 + iPadOS14 and iPad Pro 2015+iPadOS13 and does not seem to happen.

Looking through the code I think that if the scene is "heavy" for the device this could happen, I've made some changes that I think should help, but since I can't trigger it, it's hard to tell if they will do the job. Please let me know if there is a specific way to trigger the issue, as that will help a lot! 😉

Hi. ✋
Thanks for reading!

The environment is iPhone 8, iOS 14.4.
And no background apps.
The only object is one default primitive sphere.

After that I tried a few times and autosave may not be relevant.

After sculpting, if the app is
-[Scene]>Save>closed app,
it doesn't turn black, but if the app is

-[File I/O]>Save>closed app,
it turns black...🥺

By the way, I couldn't reproduce this on my iPadPro 2018, as you know.

Hi ullmeo

I just wanted to give you a small update on this.

I made some changes that should avoid this issue but since the changes are in a very important part of the code (when the app is moved to the background) I prefer to keep them for some time in testing before releasing, this has been in testing for 1 week already, I might keep it in testing for a couple more weeks before releasing.
