PicoFBT
by Feli
PicoFBT lets players on standalone Pico VR headsets use Pico motion trackers for full body tracking in Minecraft 1.21.1, running through QuestCraft with Vivecraft.
What it does
PicoFBT adds native Pico tracker support to a Vivecraft setup, so the body follows movement captured by Pico Motion Trackers. Pico 4, Pico 4 Ultra and Pico Neo 3 headsets are named as supported, and a minimum of two trackers is needed. The mod is built for standalone Pico headsets running QuestCraft, and its calibration uses a T-pose held for three seconds before play begins.
Movement is read through Pico's own body tracking API, which the mod uses to keep the avatar responsive in real time. Where a tracker cannot be seen directly, Pico estimates additional tracking points. Vivecraft is required, and the mod is published for Fabric only, on Minecraft 1.21.1, under the MIT License. Its source code and issue tracker are public, and the project is open source. Installation means placing the mod JAR in the QuestCraft mods folder, or adding it through a mod manager.
