Harald but does not provide any means to write or modify the input .json file out of the box.

Did not see here that nothing can be done beyond running the animation. Thank you all.

Harald Perhaps you could describe what you would like to achieve, then we could provide more helpful information on how you might do that.

Since there is no plugin system here we are trying to think of ways of editing our animations with another software after the animators have done all the work with the spine editor. I was exploring blender then now am thinking of unity.

Harald spine-unity runtime (like all Spine runtimes) reads the skeleton and animation data from the skeleton .json asset, but does not provide any means to write or modify the input .json file out of the box.

Does this mean I work with c++ or c# runtimes ?

Nate Our generic runtimes are intended to be extended, they do the loading and data preparation and provide an API for manipulation, you just need to add rendering.

Meaning I cannot manipulate anything on Spine editor ? I think I will go with another route that will be less error prone - Unity runtime - use Unity API to manipulate the json on the unity animator. With this I get all skeleton & animation data

The spine-unity runtime wraps the spine-csharp structs and functions and exposes them as Unity components. Additionally, the spine-unity runtime imports files exported from the Spine Editor and stores them in custom Unity asset types.

Nate It should be possible to use our Spine Runtimes to write a plugin that brings Spine animations into Blender

Thank you for your reply @Nate which runtimes are best I can also not find any python based runtimes. Only c++ can be wrapped with python bindings. Can you confirm if this would be a possible method or which runtimes are you sure I can extend ? c# ? or c++ is just fine

Thank you for the reply. I could not find any runtime for blender. Is this in the works or it is not really possible to achieve this ?

Are there APIs for leveraging the editor. Like an api to do a certain action on the editor ?
