Having trouble capturing precise movements such as an actor touching their hands palm to palm? Let's talk about why.
The sensors for all of our products are inertia based, meaning that they only record relative location and rotation data. That’s why adjusting the body dimensions can help improve their accuracy. Getting a 1:1 match is not always possible, but the closer you get, the less cleanup you will need to do later.
Ways to improve capture accuracy
Use the body size manager to select a body size template and adjust individual dimensions as needed. The closer the dimensions of the character are to your actor, the more accurate the capture data will be. That same principle applies when retargeting your actor's performance to a digital character. It is rare that an actor's proportion will exactly match those of their character, so some cleanup should be expected.
Use this chart as a guide when measuring your actor. Make sure to measure from rotation point to rotation point:
Other ways to help improve accuracy include:
- Proper sensor placement and calibration
- Wearing tight fitting clothing under the sensors
- Making sure the straps are secure so that the sensors do not move during capture

Why is the BODY SIZE MANAGER important?
The BODY SIZE MANAGER contain preset dimension sizes for male and female actors. You can create and customize your own measurements as well. Creating a body size measurement that works 1:1 to you will increase the motion data accuracy. Please see the Axis Neuron user manual for details on how to measure the bones.
