This article goes through how to create an accurate actor profile for your motion capture performer
Introduction
When setting up your Smartsuit, you will need to pair the live input to a specific actor profile. That actor profile needs to accurately reflect the measurements of the actor in the Smartsuit.
You will find the option to add an actor profile in the top left of Rokoko Studio. Simply click on the little '+'
Name
The actor profile needs to be named, this is up to the user how they want their naming convention to be. We usually recommend the name of the actor, as even if the actors have the same height their body measures might not be the same.
Colour
You have the possibility of colour-coding the actor profile so you're sure who is who if working with multiple Smartsuits and actors in a scene.
All measurements
The actor profile will be ready to use after inputting just the height of the actor.
Based on the height, Rokoko will estimate the other measurements of the actor, and these are usually quite accurate. But for the most precise data, it is recommended filling out all the measurements manually to fit the actor perfectly.
If you choose to do this, please continue reading to ensure that you measure the various elements in the most accurate way.
