Do you remember the article, about mocap files? Where PlantPerson talks about motion capture technology and point to us a tutorial, showing how to use mocap files with Blender? Well, in this tutorial a very large library of free mocap files is used. We just found another huge mocap library, with a lot of files to download for free.
This library belongs to the Carnegie Mellon University, and the files can be used in commercial projects. If you want to browse their mocap database, visit this link. The mocap files of their library are in the ASF/AMC format. Which are not compatible with Blender.
But, we can convert these files easily with a free tool, called amc2bvh. The BVH file format is fully compatible with Blender!
