  • down grad from spine 4.2 to spine 3.8 is not working

    inglese

hi!
I am really looking for help whit spine downgrade of 4.2 version to spine 3.8.99.
I create the downgraded export, and want to check it back in older sine, but I can not even import the file in to the older version. I always get this massage back:
" An error occurred while importing the skeleton. Please be sure to choose a valid skeleton JSON or binary file.
JSON version: 3.8-from-4.0-from-4.1-from4.2.36
Spine version: 3.8.99"

I also screen recorded what I experienced:

thanks upfront

To downgrade a Spine project from version 4.2 to 3.8.99, you need to follow a specific process to ensure compatibility. Here are the steps you should take:

  1. Export JSON from Spine 4.2: Open your project in Spine 4.2 and export the skeleton data as JSON. Make sure to set the version to 3.8 in the export settings. This can be done in the export window by changing the Version option in the JSON format options from 4.2 to 3.8.

  2. Import JSON in Spine 3.8.99: Open Spine 3.8.99 and import the JSON file you exported from Spine 4.2. This should allow you to open the project in the older version.

Here is a visual guide to help you with the export settings:

If you still encounter issues, ensure that you are not using any features in Spine 4.2 that are not supported in Spine 3.8.99, as these can cause compatibility problems.

For more detailed information, you can refer to the following resources:

If you follow these steps and still face issues, please provide more details about the error messages or any specific problems you encounter.

I tried exactly the same, but it does not allow me to open it at all in spine 3.8.99 .
As I saw in other posts to lose the anim curves is a known phenomenon, but I am sure, I have to be able to open in the older version, for a check.

    I will see what the problem is as soon as we receive it.

    (Just to be sure, I tried to see if Spineboy JSON data exported from 4.2.36 with version 3.8 could be imported into 3.8.99. There was no problem and the import was successful).
