how do you use BVH files?

how do u use the BVH file like the zombie one that just came out

You just file import the BVH file.

You can specify that it imports an armature or empties. If you don’t already have an armature, use the default setting of Armature to get one. If you already have a rigged character, you can import as empties and simply parent your control items to the empties.

Do you have a link to the zombie BVH?

Here’s the story on Blendernation that links to the files.
