Hey thanks for letting me know about your issue. The textures should be included in the pack. Did you import everything from the included zip file or just a part of it. Some components are in the "shared" folder
Hi! Yes, I imported the full zip, including the shared folder.
The source PNG textures are present, but Godot reports missing generated .ctex files from res://.godot/imported/, for example flash_03.png-...s3tc.ctex.
Reimporting the PNG textures did not fix it. It looks like some affected scenes may be referencing old generated Godot import cache files instead of the source PNG textures directly.
I can send screenshots and the exact error log if needed.
