  • 3D  - We are in the process of updating our 3D avatar T-Poses. As a rule of thumb, if the avatar has… thumbs, it will likely work. Avatars that do not have arms and or hands will not work with Ultraleap hand tracking. 

  • VRM 

  • Ready Player Me

Setting up your Leap Motion Controller

First of all, you will need to download Ultraleap’s Tracking Software for Windows (4.1+) before beginning.

To get started, plug in your Leap Motion Controller. Update the settings in the Leap Motion Control Panel by searching Leap Motion in your PC settings. The Tracking Settings are especially important.

Animaze supports Ultraleap hand tracking software in both Desk Mode and Chest Mode. 

Animaze supports Ultraleap hand tracking software in both Desk Mode and Chest Mode.

Many of us prefer the chest mode option. 


Ultraleap chest mode option recommended

.This is because the Leap Motion Controller has a specified area that it can track. Mounting the tracker to your chest positions the area tracked such that you can move your arms and hands more naturally. Additionally,  with this setup, finger tracking tends to be more accurate. Desk mounting is quicker to set up and often captures large gesticulation better than chest mounting.  

There are many ways to mount your tracker to your chest. You can purchase a Leap Motion chest mount online. Try searching websites like eBay and Etsy. Or, you can tape the tracker to your chest. Most of us on the Animaze use tape or velcro strips.

But we are crafty like that

Toggle on Show Tracking Camera Position.


If you are using a desk mount, you will see the left image. If you are using a chest mount, you will see the right image.  If you don’t want the overlay to show during a stream, it’s important to turn this overlay off.

Use the controls to match the Leap Motion Controller overlay in Animaze to the positioning of your actual tracker. Once the tracker overlay in Animaze matches the tracker placement on your desk or chest, you may consider tweaking the Tracking Camera  Positions controls (top controls) to account for your avatar’s arm length. For example, if your avatar has short arms, you may consider nudging the Z origin outwards to get as much arm length as possible
