Thanks for the report for 4.0.6, we mentioned very secretly on the release note that the 4.0.5 version is compatible with 4.0.6, I’ll update the format of the readme to make it clearer.
There are currently no short-term plans to add/port new features to the unity Live Link sample. Its purpose was to show how to receive body tracking data in Unity (it allowed using Fusion), but it’s indeed pretty “bare”. That being said, since both project codes are available and pretty similar, you could do the porting of the features you need in your project without much difficulty. We want to keep it as simple as possible on our side.
The rule for porting is that anything that uses an SDK feature should be managed in the C++ sender, and the pure Unity code is to be added to the Unity project.
