Blender character animation

1. Download the BlenderAddon and install the Blender.
2. Install the Addon in Blender: Edit -> Preferences -> Add-ons -> install -> select ROMP/romp/exports/blender_mocap.py
   Click to active the 'Real Time Mocap' add-on.
3. Run the ROMP webcam demo code:

cd ROMP
sh scripts/webcam_blender.sh

Export the results to fbx

Currently, this function can only export the motion of a single person at each time. Therefore, please test it with demo/videos/sample_video2_results/sample_video2.mp4, whose results would be saved to demo/videos/sample_video2_results.

1. Prepare the data:

Please register at this link and download the SMPL_unity_v.1.0.0.zip from SMPL for Unity.

Then set the path of the downloaded files at convert_fbx.py. For example,

male_model_path = '/home/yusun/Desktop/unity/SMPL_unity_v.1.0.0/smpl/Models/SMPL_m_unityDoubleBlends_lbs_10_scale5_207_v1.0.0.fbx'
female_model_path = '/home/yusun/Desktop/unity/SMPL_unity_v.1.0.0/smpl/Models/SMPL_f_unityDoubleBlends_lbs_10_scale5_207_v1.0.0.fbx'

You can also choose the gender of animated model via setting gender=male or gender=female

3. Run the code:

cd ROMP/

python export/convert_fbx.py --input=demo/videos/sample_video2_results/sample_video2_results.npz --output=demo/videos/sample_video2.fbx --gender=female
# on Windows
