While there isn't a specific tutorial for exporting from Spine 2D to Vtuber Studio, there are discussions and prototypes that explore using Spine for VTubing. For instance, the Spine Pro Vtuber Working Prototype thread discusses improvements and techniques for using Spine in VTubing. However, integrating Spine with VTuber software may require custom solutions or plugins, as it depends on the compatibility of the VTuber software with Spine's runtimes. You might need to explore how VTuber software works and see if you can integrate Spine's animations into it.

Pix Currently, the following third-party tool is available for Vtubing using publicly available Spine skeletons: https://esotericsoftware.com/forum/d/16925-spine-pro-vtuber-working-prototype

We remain interested in developing official tools to support Vtubing, but due to a lack of runtime development resources, other tasks currently take priority.
