BioVision Motion Capture (BVH)¶
Reference
- Category:
Import-Export
- Menu:
Imports or exports bvh-files or files with BioVision Hierarchical data or data of a skeleton (rig) including its animation. Useful for importing data from motion capture devices.
Enabling Add-on¶
This add-on is enabled by default, in case it is not:
Open Blender and go to Add-ons section of the Preferences.
Search “BioVision Motion Capture (BVH) format” and check the Enable Extension checkbox.
Properties¶
Import¶
- Target
The motion capture data type.
- Armature:
The bvh-file contains an animated rigged skeleton such as a walking motion capture.
- Object:
The bvh-file contains a static (not animated) mesh object such as a character model.
Transform¶
- Scale
Factor to increase the physical size of the BVH.
- Rotation
Rotation order of the BVH.
- Forward / Up
Since many applications use a different axis for pointing upwards, these are axis conversion for these settings, Forward and up axes – By mapping these to different axes you can convert rotations between applications default up and forward axes.
Blender uses Y forward, Z up (since the front view looks along the +Y direction). For example, its common for applications to use Y as the up axis, in that case -Z forward, Y up is needed.
Animation¶
- Start Frame
The start frame, in Blender, to start playback of the BVH animation.
- Scale FPS
Scales the frame rate from the BVH file to the scene frame rate set in Blender, otherwise each BVH frame maps directly to a frame in Blender.
- Loop
Cycles the animation playback.
- Update Scene FPS
Set the scene’s frame rate to match the frame rate of the BVH file.
- Update Scene Duration
Extend the scene’s duration to match the BVH’s duration.
Export¶
Transform¶
- Scale
Factor to increase the physical size of the BVH.
- Rotation
Rotation order of the BVH.
- Root Translation Only
Only write the translation animation channels for the root bone.
Animation¶
- Start / End
Sets the range of animation to export to the BVH file.
