Broken 2D PSB Models after upgrading Unity from 2019.3.7f1 to 2019.4.5f1 LTS

,

We have upgraded our Unity version to LTS today, but unfortunately, it seems that the PSD importer causes some trouble with the new Unity version.

All of our PSB based models for 2D animated characters lost their heads during the asset import process after the upgrade because the importer changes the PSB’s meta files without a visible reason. This causes some sprites to either completely swap their position, or get some of their properties completly deleted.

The layerID and SpriteID of some sprites inside of the PSB files are changed as well.

Even if I manually revert the changes within the meta file directly using a text editor it won’t fix the issue, but Unity keeps modifying the meta files again and again.

I have attached some screenshots of the corresponding diffs in order to show the file changes.

Hope someone can help us with that.

Many thanks in advance!

Kind regards,
Christian

Sorry you’re having problems upgrading. Have you submitted a bug report for this yet?

If you could submit a bug report with a project that has an example of the buggy PSB, it would help us narrow down and fix the issue sooner. If you can submit a bug report, go ahead and post or DM me the number so we can get to it sooner.

Hi ed_s, we have submitted a bug report with the following ID: (Case 1266141)

Note: This also happens using the latest LTS release (2019.4.9f1) with latest verified PSD Import & IK Packages.

Oh boy. Hopefully you experienced this bug in a cloned side branch or a duplicate project of your core project. That would really stink for that to happen to a production project.

Yes, we did the upgrade in a separate git branch, so that we can still progress with the master branch. Nevertheless, it would be good if the bug gets fixed and we therefore won’t need to do all the rigging and animating again in order to make the project compatible with 2019 LTS.

Understandable. I know it can be terribly frustrating when absolutely nothing about the asset items themselves are changed and they break in such dramatic ways over an upgrade. Especially if this were a change that had to do with hidden meta files.

The fix in 2021.1 with PSD Importer version 5.0.0-pre-2 has fixed our issue. :slight_smile:
