I’ve imported C3D motion capture data into Blender 4.0 using the add-on from https://github.com/MattiasFredriksson/io_anim_c3d. The result is a point cloud, but the data is organized in an object hierarchy. I can’t select individual points for use because selecting one selects the entire hierarchy. I’m looking for guidance on how to retarget this point cloud C3D motion data to an avatar. What steps should I take?
Hello and welcome aboard!
You are doing something wrong in the import process. The result shouldn’t be a point cloud, but an armature that moves when the animation is played back.
I looked up the github link you posted and browsed thru the code a bit. It hasn’t been updated in 3 years, so that might be one reason why it’s not working. There’s also an option to create an armature, which is set to True by default, but maybe that option was unchecked? IDK
Run the import process again, making sure the create armature option is set, then open a blender console window to check for error messages.
Chances are the importer is out of date with current blender versions…
