Once the poses are captured the user will need to go into the Hand Training tab, select their preferred calibration settings and then click on Train to be able to see the live hand motion.

HE 2.X:

 

d) The Tutorial button for the Express Calibration from HE 1.5.3  is no longer present in HE 2.X, the video can still be found in our Knowledge Base User Guide article.

HE 1.5.3:

 

e) Hand Engine 2.X does not support the Export Performer feature present in HE 1.5.3 (see example below).

HE 1.5.3:

The current solution in HE 2.X is to go into Advanced Calibration -> Hand Training -> Export Calibration. The user will need to export the calibration for each hand separately.

HE 2.X:

f) Hand Engine 2.X does not support the pose Cut, Copy, Paste and Rename features present in HE 1.5.3 (see example below).

HE 1.5.3:

In HE 2.X the Pose Editor tool has been introduced, which is a complete redesign of the custom pose creation process from HE 1.5.3. The Pose Editor tool can be accessed via Windows -> Pose Editor, further instructions on how to operate the tool can be found in our Knowledge Base User Guide article.

4. Recording / Playback

Hand Engine	Global File Playback (a)*	FBX Record Target (Hands or Full Body only)	FBX Start Key Data (timecode or frame 0) (b)*
1.5.3
2.X		(saves both FBXs at the same time)	(in HE, Windows → Settings)

 

a) Hand Engine 2.X does not support the Global File Playback feature present in HE 1.5.3 (see example below).

HE 1.5.3:

In HE 2.X, the recorded files will begin the playback as soon as the raw data file is loaded in Hand Engine. This means that the left and right hands will end up out of sync by the time the last hand data is loaded. 
NOTE: Our Developers are currently working on improvements to the playback feature.

 

b) In Hand Engine 2.X the user is now able to select when to start the keyframe for the recorded data (see example below).  In HE 1.5.3 the keyframe starts at timecode by default.

HE 2.X:
