Thumbnail gone after asset/bp name changed or moved


Not critical but tiring bug (I think bug or better omission). After renaming blueprint with a thumbnail (created before by Asset Actions/Capture Thumbnail) thumbnail is cleared. Clearing is not necessary, because this is same blueprint (in this case actor bp), with same object etc, just name changed. With a lot of actor blueprints for rename what is sometimes required, this is no good.

Thank you.

Edit - topic changed, thumbnail gone when asset is moved to different directory.


I was unable to reproduce your issue on our end, I have a couple of questions to help narrow down the issue you experiencing.

  1. Can you reproduce this issue in a new project?
  2. If so, could you provide a detailed list of steps so that I can reproduce this issue on our end?

I can’t see gif in comment, so next post.

  1. this is new project, I just test on new created and it happens too

Hello again,

Thank you - fingers crossed - I have tons of different inventory actors and this is important I think :slight_smile:

This is still not resolved, from 4.16.3 Unreal Engine Issues and Bug Tracker (UE-50575)

And still not solved in 21.
I wonder if there’s a shortcut at least, so we can capture thumbnails fast.

Still not resolved 4 years later. This is a major issue for those of us on the creative side who rely on thumbnails.

I agree, this is really annoying and should be fixed

Still an issue in 5.2.1. The link to the issue shows “Wont Fix”. Now either Epic are bunch of @#$!?/'s, or it is a version reason. It better be the latter.

As of UE5.3 you can fix your thumbnails by resaving assets with broken thumbnails. For example, you select assets with broken thumbnails, right click one of them → Asset Actions/Load, then after assets are loaded, you again right click selected assets and click Save. After save is done, your thumbnails will be fixed. Probably works same way on other versions too.
