  • Alternative to open ".skel.bytes" files

Hello, I would like to know if there is another alternative to open files ".skel.bytes" without having to have the program, since I do not have the money to acquire it.

Here the problem is that I only have 3 files that are:
the file "skel.bytes", ".atlas" and the image ".png" of the skeleton, I do not have the file of the original project ".spine".

Try some time with Unity using the runtime that is here in the forum but I always get an error that the file ".skel.bytes" is invalid.

I hope you can help me and anyway I leave an example here.

Binary is very sensitive to changes. Literally any change to the binary format means you can't read old bytes. You need to use the exact runtime version that matches the editor version used to export the binary skeleton data. Normally you would have the .spine project file and you would re-export for the latest runtime, as compatibility is done at the project file level, not at the JSON or binary data level.

Please note there are some restrictions when using the Spine Runtimes without a Spine license:

I see, if in this case all the examples I have are made in version 3.5.51, then we will have to wait to get the program ...

FWIW, the 3.5 Spine Runtimes are here:
Release 3.5.51

When I import spine-unity runtime and C# runtime I get this error!

I delete this variable but doesn't works! :c

This is error

You have to use the spine-csharp runtime from the same commit as the spine-unity runtime. Newer spine-csharp versions will not work with the old spine-unity runtime.
