This is really cool! I wish you all the best with this project. It's nice to have some native Linux VTuber software.

When loading my .vrm into the application, it appears none of the colors I picked in VRoid Studio is applied (different strands of hairs are different colors for example), and the face is just completely detached from the head.

Here is the console output: https://gist.github.com/copygirl/c2ea34994da5861ee152519b3af487d5

Wouldn't want to open another thread though I'd like to comment: It would be nice to see this be open-sourced. Might be nice to add VR hand controller support (such as the Index controllers), for people who have them, but no Leap Motion. (Also, you've gotten Leap Motion to work on Linux? Wow!) If this was open source, other devs could tinker with this without you having to divert your attention. Anyway, still, thank you very much!

Are you using vertex colors or material colors?
Can you send me VRM file?

I don't have such plans, but this could be changed.

I don't have VR controllers. Leap Motion still works, but it stuck on old SDK 2, because developers abandoned Mac and Linux platforms. You can also use regular webcam for the hand tracking, it kinda works but still buggy and unfinished.

I could open source some plugins or API and make a documentation  for it in near future. The app is plugin based, so it's pretty easy to add more tracking devices to it. But I doubt there are more Linux VTubers.

Not sure which VRoid Studio does when I select the color in its UI.
Where can I privately sent you the .vrm (or a link), ideally?

I know the feeling. I've only dabbled with VTuber related software development for a little bit, but I've already had my fair share of frustration, especially because Oculus does not make its lip-syncing library available for Linux.

I did notice, and I've tried it - semi-successfully! I've been dying to have some hand-tracking in my setup, or support / help with some development. Currently I only know about OpenSeeFace - and it doesn't help that I'm not a big fan of Unity.

But I doubt there are more Linux VTubers.

It's possible to look up VTuber+Linux tags on Twitch, for those who use them. We can only become more numerous!

I'm already using them xD

I have fixed colors and skinning.
