I remember supported this project on patreon for a few months but never had a single chance to play. Considering supporting it again, but I do have a few questions those are very important to my personal uses. First, do you guys support openai compatible llm API backend? I kinda want to use my own open router API. Second, I would also need multilingual TTS that can pronounce Asian languages properly, not sure which TTS you guys use or if you have a system where I can use my own API? I personally do have API keys for Azure, Elevenlabs, Minimax, Fish Audio. If the system supports any of those backend, I can totally use my own API. Third question is, do you guys only support importing of Vroid model? Or any custom VRM model will work?
