This video shows the whole process of setting up Avatars in Holodance. The first step is setting up the correct roles for the Vive trackers in SteamVR. This only has to be done once and then also works for other application that have Avatars, like LIV, for example. Once that's done, you can select an Avatar. All Avatars immediately use head and hand-tracking. For feet and waist, an additional "Calibration" step is necessary. This is because we cannot rely on waist and feet trackers always being in the exact same position.
