Hi all,

I have a problem with BVH files that don't stand still. Sometimes, it is impossible to hide the feet of a character and I see their feet slide unnaturally with respect to the ground, even if the character is idle. It is not only the feet; it is the whole character that slides. How can I lock this character or make it stand still? In other words, how can I make this BVH file steady? Any clues would be appreciated.

After considerable experimentation with BVH files, I've concluded that Poser doesn't seem to do that good a job of scaling down the motion data to match the figure.

I often reduce the hip translation by ~50%, using one of ockham's Python scripts, which I'd modified specifically for that purpose.

Anakele sells a Python utility at Content Paradise which can help correct the sliding -- BVH Constraint.  He's posted a tutorial video on YouTube.

I have hundreds of BVH files and i doubt one of them actually works 100% with Poser. When a company does any sort of motion capture and sells it as a BVH it generaly means it is used for a few formats so not really being 100% compatable.
As pain staking as it sounds i take a BVH i like and then do all the adjustments needed though the wave editor. I never had much luck with python methods.
In fact i recently did my own motion capture avi (check out the video center "test walk") and got a brilliant bench mark for a walk cycle using the .avi as a background and just simply matching the poses. it took about a month to refine mind lol
Patience is the key, if it worked "out of the box" then everyone would produce great animations ;)
Good luck with your results.

Great tips, guys. I feel that this BVH constraints script might be useful.
