anyone know of a way to fix this??

Lots of painful, tedious tweaking with the animation graph.

Hey, dragon. Maybe a little more explanation? is it a poser bvh, or was it created for another program? Have you tried on both x & y axis, scaled and not scaled? If it's not a Poser compatable BVH, about the only thing you can do is Grab the Lifeforms Demo, and use it to convert, and it's a REAL pain.

Most of the poser bvh files are designed for poser 4.0 standard characters. Even the poser bvh files won't work with the characters you will probably want to work with. There is a difference in the naming conventions between standard bvh and poser bvh files. It is the shoulders and necks that are usually out of synch. Also, since there are no motion sensors on the fingers, the hands have to be done with hand poses. There is a new utility called Motion Corrector v1.0 in the marketplace. Minsk makes it and it cost $50.00. I thought about buying it but decided to wait until someone else tried it and recommended it.

A little more explanation of what the BVH files are doing to your character would be helpful. I use alot of public domain BVH files that are not joint mapped for the millemium characters it is tremedous help to have the propack to scale them upon import. but spikes the graph editor usually reveal all of the problem areas to be corrected .

If the BVH has "neck" but your figure has "upper neck" and "lower neck", then the neck won't move. Similar problems for other alternate names, and additional body parts. Most non-Poser BVH files have "shoulder" so when they are applied the motion goes to the shoulder, rather than part to the shoulder and part to the collar, which usually looks better in Poser. And I got one freestuff model that has parts like "left_hand" instead of "left hand", so of course most BVHs don't fit it! This is why the MaGaMocap web site has many versions of its motion files, including special versions for Victoria and Michael.

You can edit the BVH files using a text editor. This lets you see the body part names. You can get the body part names from Poser of your character. That lets you see any differences (upper and lower neck) versus just neck. You can even change the BVH file. It is possible to screw that up and the BVH file is unusable. However, even if you get the names to jive, the joint parameters vary for the different characters and from the model which wore the motion sensors. The scaling features with PPP and Poser 5 helps but you still have to work on the result.
