Welcome to the Isadora community forum.
What kind of Skeletal tracking are we talking about? We support a variety of Body tracking solutions with our OpenNI intergation, which can be found here;
This bundle includes our OpenNI Tracker Plugin, the Skeleton Decoder plugin and our Skeleton Visualizer that allows you to draw the Skeleton on your stage.
You said that you tried this / had issues with it? Could you elaborate a bit more about your setup, what kind of sensor, what kind of computer are you using (Mac / Windows, and what version of the operation system)
