Nuitrack AI in Unity and Unreal is jittery. Seeking how to improve quality through software and environment

Hello @ADecker_Roto
Which sensor do you use?
And please send screenshot with depth from Program Files\Nuitrack\nuitrack\nuitrack\bin\nuitrack_sample.exe
Direct mapping is very sensitive to joint stability. Indirect mapping is probably better for you. You can test different types of mapping on the AllModulesScene stage

Is there a best practices document for height/angle of camera and what’s in the background to improve reading? We will likely need to work from a low/steep angle for our use case.

Documentation

Are there more steps to activating nuitrack AI than that post implies? Where do I find that information if so?

No. It’s works.
Alternatively you can just enable ai in this component, without editing the nuitrack.config (But if the algorithm is already enabled in the nuitrack.config, then its value will be considered a priority)
