Blaster Thank you for sending us the skeleton data files.
I imported them into Spine PRO 4.1 and confirmed that the skeleton displays correctly without any issues.
However, if you are not sharing the data for the purpose of reproducing a problem, but rather because these are the only files you have, please note that they may not import correctly in the trial version of Spine. This is because the Spine Trial always launches the latest version of the editor.
While Spine project files saved in Spine 4.1 can be opened in newer versions, skeleton data exported from 4.1 can only be imported correctly into Spine 4.1.
Therefore, if you only have the exported skeleton data files, please try to locate the original Spine project file or contact the creator and ask them to provide it.
By the way, if your reason for displaying the skeleton in Spine Trial is to preview it—for example, to check animations—you can use Skeleton Viewer as an alternative.
You can download the version of Skeleton Viewer that matches your skeleton data from the Download section. (Please note that Java version 9 or later is required to run Skeleton Viewer as a standalone application.)
