How to Create Realistic 3D Characters with Brekel Pro Body v2
If you are interested in 3D animation, you may have heard of Brekel Pro Body v2, a Windows application that does marker-less body motion capture of up to 6 people using a Kinect sensor[^1^]. This software allows you to record and export high-quality body animations for your 3D characters, without the need for expensive suits or markers. In this article, we will show you how to use Brekel Pro Body v2 to create realistic 3D characters with ease.
What is Brekel Pro Body v2
Brekel Pro Body v2 is a software that uses the Microsoft Kinect SDK tracking and many custom algorithms based on 15+ years of professional motion capture experience[^1^]. It can capture the movements of up to 6 people at the same time, from your living room or office, and record them as FBX, BVH, TXT or CSV files. It also supports point cloud data, audio data, 2D face tracking, hand states, lean and clipping[^1^].
Brekel Pro Body v2 works in real-time, so you can see the results of your capture immediately. It also has a preview option that lets you review your data after recording. You can adjust the smoothing/filtering settings, export a mathematical T-pose, resample the output data to custom frame rates, and sync recording between multiple Brekel apps on the same machine or different machines on the same network[^1^].
Brekel Pro Body v2 can also live stream and record directly to Autodesk MotionBuilder using included plugins for 2009-2020 versions. It can also live stream directly to the Unity3D game engine and Unreal Engine 4 using included example scripts and scenes. Additionally, it can live stream joint data over OSC (Open Sound Control) to other apps[^1^].
How to Use Brekel Pro Body v2
To use Brekel Pro Body v2, you will need a Windows 8/8.1/10 machine with a USB 3.0 port, a DirectX 11 capable GPU, 4 GB or more RAM, a dual core 3.1Ghz i7/i5 CPU or faster, and a screen resolution of at least 1280x1024 (recommended: 1920x1080 or higher)[^1^]. You will also need a Kinect for Windows v2 or Kinect for Xbox One sensor[^1^].
Once you have installed Brekel Pro Body v2 from here, you can follow these steps to create your 3D character animation:
Connect your Kinect sensor to your computer and place it on a stable surface about 1.5 meters above the floor and about 2 meters away from where you want to perform[^2^]. Make sure there is enough space around you and avoid direct sunlight or reflections on the sensor[^2^].
Launch Brekel Pro Body v2 and select the sensor tab. You should see a live feed of your sensor's view in the main window. You can adjust the sensor settings such as exposure, alignment and floor compensation if needed[^1^].
Select the output formats tab and choose the file formats you want to record. You can also set the output folder, filename and framerate. You can enable or disable additional data such as point cloud, audio, face tracking and hand states[^1^].
Select the record tab and click on the record button. You can also set a start delay if you want to have some time to get ready before recording. A countdown will appear on the screen and you will hear some beeps before recording starts[^1^].
Perform your motion in front of the sensor. Try to stay within the sensor's field of view and avoid occluding your body parts with other objects or people. You can see your skeleton overlayed on the sensor's view in real time[^1^].
When you are done, click on the stop button or press ESC on your keyboard. You will hear some beeps when recording stops. The recording length and any dropped frames will be displayed on the screen[^1^]. 061ffe29dd
