[aragonkou]

Im using Paper 2D to make a dungeon crawler and I use flipbook as character animation.

It works well when PIE, but after packaging, all flipbooks disapper

engine version is 5.3.2

Tried anyway i know but did not solve.

Play in editor：

packging on windows：

finally, i revert version and find it cause by a plugin i didn’t use.

I shut it down and it works
