I have a bvh file for the charher horse walking in place,how do i edit it to move.

You don't. Read your Poser manual on page 340. It will tell you how to create a walk path for your figure to follow.

Hi Im curious.. You Are saying you can  now Add Walk paths to IMPORTED BVH Files??
I Ask because the OP does not appear to be using posers walk designer

FORWARD TRANSLATION USING THE GRAPH EDITOR

wolf is right i'm using a imported bvh file for the charger horse and you cant apply a walk path with walk designer,but i still need to know how to make it move forward.

[**waiting on a long render – forgive the stream of consciousness & speculative post… ]

If you don't show the feet/hooves, you can just translate the Body.

The problem with a continuous Body translation, as you’ve no doubt discovered, is that the hooves on the ground will be continuously moving, and thus will likely appear to slide.    

hmmm ... or perhaps you COULD nail the translation speed just right, if the BVH is really accurate and if it was a full-out gallop.  However, with loping, trotting or walking, with their less linear, more sinusoidal or lurching speed variations, a continuous Body translation will no doubt still appear unnatural.

Alright, my bad. You could consider letting the horse walk in place and moving the background.

"Alright, my bad. You could consider letting the horse walk in place and moving the background."

LOL the worst possible solution for such a simple task for anyone remotely familiar with the poser graph editor

In short you need to translate the hip along the Z axis with a straight Linear interpolated curve

that Video i linked to above is from me trying to explain this very thing to another user here.

 

I had  poser"Dork" walking in place and i simply adjustment of  the linear curve of his hip forward movement
until his forward motion matched his footfalls.

very Simple.

Well, since Wolf359 is going to ridicule every suggestion I make, let him help you and I'll just go over here and hang my head in shame.

let us know how the horse anim goes.  it's more difficult getting 3 hooves to stay in their poser (x,z) locations whilst moving the 4th hoof, compared to human feet.  a running horse is even worse: anywhere from two to 4 hooves can be off the ground in any given frame.  I dunno how well the no-foot-sliding script or drop-to-floor-in-all-frames script would work on a horse.  wolf is not ridiculing ya - he just has alotta experience and wants to help others with their anim probs, e.g. learning how to use graphs.

I know. Just messing with him.




wolf359 posted Wed, 15 June 2011 at 2:39 PM

To the OP :
if you already  have a satisfactory run/walk in place animation you can move him forward literally with TWO KEYFRAMES one at frame one and one at the last frame
the Value at the last from with LINEAR INTERPOLATION will determine how fast he moves forward

Like HERE:

if you are not experienced with the graph editor then please start HERE

first.

Wolf,

That was my post you responded to a while ago.  I tried your method and got very close, but could never quite get the figure to completely stop "skating."

Perhaps the type of walk or the gate (this was a robot) prevented total success.


wolf359 posted Fri, 17 June 2011 at 2:59 PM

Hi was your interpolation set to linear

if it was spline you will never get rid of the "skating" effect

No, it was set to linear.  I followed your video clip.  Either I'm a bit ham-handed when it comes to the graph or your method won't work with this particular figure and walk cycle.  Though I am puzzled that it even worked for you with a horse!

There wasn't any sound on the first one but I enjoyed the second one immensely. Thanks Wolf.

Hi glad you enjoyed it sir!!

check the list to the right of that video for more animation tutorials in that series I did two years ago.
