1. when exporting bvh to be used in animation for a> the same character or b> other characters, what does the scale bvh option do, either in exporting or importing? for instance, does this compare different character set up rigs, the rot or bend values, to a particular standard and interpret them? 2. is there some way to export bvh files that does not write keys to every single frame? i spend a lot of time making the animation with as few keys as possible, but when i export the bvh and reimport it. whammo, the entire palate fills with keys making modifying the animation tedious at best. not to mention how wasteful it is for keys to register on the nonkeyed elements and morphed elements. gracias for any comments.

1. When importing, the scale option attempts to compensate for the relatively (compared to other applications) small scale of Poser's characters. If it isn't used, the hip translation might place your character three hundred feet above ground level.

2. No. Every frame is a keyframe. It's a limitation of the BVH format. However, after importing a BVH, you can have Poser resample the keyframes.

not to mention how wasteful it is for keys to register on the nonkeyed elements and morphed elements.

Morph channels aren't included in a BVH. Just rotation and (for the hip) translation.

oh okay i get that..so the scaling is not from one character rig to another but a way to compensate for the tiny size of the poser scale...(too bad...we need an app like that). and i guess the later part means no bvh for faces but i guess that makes since since the standard for that seems to vary drastically. and i guess bvh is about bones really. wow, though...so all there is in bvh is a bunch of rotation, and translation of one element. that is neat. anyway, so if the bvh is made in poser for poser, no scaling is neccessary. thanks for the reply little dragon.

Why not just save an animated pose file if it is to be used for just one character? That way you can include the morph channels in the animation.
