Depends actually, nitreug. Each BVH is different, and each characters reacts differently. But, for MIL characters, and you might have to test it first to see which part of the character is being distorted (especially in the shoulders). Select the body part (shoulder for instance), then go to Object: Lock Actor. This will keep the body part from distorting, but will still allow it to move. Then, after doing that to the body parts, import the BVH file to the character. Try it, and if you have a problem email me and I'll help if I can. Thanks.
