    Have a look at https://www.photonengine.com/# Or the "new" built in thing from unity itself https://docs-multiplayer.unity3d.com/ (on the last link you find an example project "boss room" that shows how to implement multiplayer. When playing over the internet, you must "just" specify the correct host)

    Project mention: How to transmit custom signal to vrchat world (AI guided 3d keypoints) | /r/VRchat | 2023-02-08

    Summary: I've implemented real-time mono-webcam full body tracking, but I'm having trouble sending this data to vrchat. This function was actually implemented on Unity, and socket communication was used in Unity. Is there a socket communication method that works with udonsharp or vrchat? Here are the solutions I reviewed. https://github.com/Xytabich/UNet I think Unet is very similar to the solution I was looking for, but the connection ID uses the person object that entered the world. I want to receive data from outside.
