A note on animation


Ok so now you have turned your BVH motion into an edited pose, however now the hands dont move at all. This is easy to fix, just go every 10 to 20 frames and add a hand pose, you may also add a facial expression or a camera movement, but use the Aux camera when moving around to examin and pose and then switch back to your Main camera before leaving the frame as so the camera doesnt switch mid animation. And finaly you may find using the Memorize and Restore functions usefull here. Find a spot in your animation where your characters position is close to where he/she started, remove the rest of the frames, add say 10 new frames and then restore at the very end to make the dance a loop or they can stop in a vogue pose, or use the Memorize at the end frame, remove the animation, restore the first frame, add new frames and move on from there !!
    Also when creating motion from your pose collections, Pay ATTN to the Hip and foot Y rotations, 2 degrees looks the same as 362 degrees but acts quite differently in animations. And if you want your character to say rotate around a prop, Try parenting your character to the prop and then rotating the prop!!

Hello,
I'm trying out some things with bvh files, what is see also is that the feet are very many times 'shaking'. Left, right, or in and above the floor. if they can't stay on the same place. i did zero figure and also drop to floor, and it doesnt help really.
Maybe you have the same experience and can you help me with it how to solve this problem.
sincerely,
alpha

May have to go through frame by frame, look at your foot rotations xyz, and compare them to your hip rotations xyz, and then compare them to body rotation xyz, this happens alot when I try to build animations from poses but after you get the hang of it its not to hard, remeber to use the memorize and restore options these can help alot. And you can always save a new pose, like the same pose with out the hip turned 360.

I guess I should add a whole section on Inverse Kinmatics. This is an option under [Figure]. Most of the characters have them already set up but you can also make your own. (reference your poser manual) Mostly this will lock a body part in place, feet hands, etc. So you should turn off IK when you first pose your character, or when you import a bvh. Then turn it back on if you need it for editing the animation. Just play with the IK to better understand it.

UPDATE !! I found this http://davedub.co.uk/downloads/ its a freeware! Its not really for making bvh files but it can help make some of the odd ones work on your Daz3d characters and you can edit out only the frames you want!

Is there any way to stop the animation in poser going back to the beginning fame???

didn't quite understand the last question, but...
my guess is that you are trying to build animations using poses, and what you need to do is open the properties panel and check the body, hip, and if using IK, the foot or hand ROTATIONS. Understand that in the window 2° looks the same as 362° however will cause all kinds of havoc in your animation if not corrected. Try this, with a new doc and your favorite character loaded with IK on, go to the 10th frame and rotate the feet y-360°, then go to the 20th frame and rotate the hip y-360° and then play the animation. This should reproduce something similar to your problem and hopefully help you understand how to fix it.
