Which BVH files to use from CMU cgspeed #2

Open hshreeshail opened 2 years ago

hshreeshail commented 2 years ago

The CMU link from the project page has 3 different types of BVH files of CMU's motion capture dataset: 1] 3dsMax-friendly BVH release 2] Daz-friendly BVH release 3] Motionbuilder-friendly BVH release

Which one of these should I use?

I tried using a .bvh file from the 3dsMax-friendly BVH release, and am getting the following error message

Python: Traceback (most recent call last):
  File "C:\Program Files\Blender Foundation\Blender 3.2\3.2\scripts\addons\avatar\__init__.py", line 475, in execute
    retarget.retarget_addon(bone_corresp_file, file_path_bvh, obj, scn.skel_rig)

I think is the 3) option. You can do several things to transfer bvh motion files to the avatar model: 1) use external addon http://diffeomorphic.blogspot.com/p/bvh-retargeter.html (my code is based on this addon) that can automatically detect bone correspondences, 2) go where the avatar addon is installed and check for the motion/rigs folder. There you can find bone correspondences between avatar model and other models, you can create a new file, for example cmu_3dsmax.txt and change bone names. Left column is avatar bone names, right column is bvh file bone names. Once you created this file, restart addon that should be detected automatically and you can use it as new option.
