I'm afraid that both the multiple models and separate configuration are nearly impossible to achieve.

Though the standard Live2D app has the feature of multiple models, I've modified the Live2D framework and added some other features that make it unable to support multiple models (since this is only made for a single model, Neptune).

Even if multiple models feature is somehow supported, the model configuration is not bound to a model, it's global, referenced here and there, so it's still impossible to extract it and bind it to model.

Thanks for letting me know, I can see what you mean.

Perhaps for one day and another project,,,, codenamed: (Live2D World)? =P

Well, this will be my only Live2D project, but perhaps someone would like to make that in the future :)
