你好！对于新的4.2beta版本里的物理约束我们团队感到非常兴奋并积极的进行了尝试，但是由于目前项目里使用的Spine版本是3.8.99，如果要升级到4.2的话需要解决大量的兼容性问题，所以想询问一下有没有什么办法可以让4.2beta里的物理烘焙成骨骼的关键帧之类的导出到3.8版本里进行使用，物理效果差一些也没有关系。Spine是否有类似Blender之类的接口可以支持编写扩展脚本插件进行版本之间的转换呢？
有没有什么方法可以让我把4.2版本的物理运算结果转到3.8版本进行修改？
Lickba Unfortunately, 4.2 does not have a baking feature yet. For more information, see Nate's answer in the following thread:

As he replied, we may be able to allow manual dropping of keys for the physics pose in 4.2, but to begin with, we do not recommend downgrading skeleton data created with a newer version to an older version editor. Even if this feature were implemented, it would not be possible to export the animation as is to the 3.8 format. Various changes have been made between 3.8 and 4.2, so if you export skeleton data in 3.8 format from 4.2, information about curves between keys will be lost and rotation behavior may not be correct.
If you would like to take advantage of the 4.2 features in your project, please upgrade both the editor and the version of the runtime you are using in your Unity project.
