Is there a way, in Poser 7, to select and animation and then paste it back in reversed?  The reason is I have some BVH files that move the figure from one spot to another, and when the resulting video is looped the character jumps back to the starting location.  I'd like to paste the animation back in to have them move back to the original position.

philc's bvh helper has a script for that IIRC.

If you render the first sequence as image files, you can then reverse the order of the files to give a smooth loop. You need to not use the first and last images on the reverse order so you get that smooth transition, otherwise you get a pause because the start and end are doubled.

I do it all the time for ani .gifs

You could also copy and paste the frames in reverse order in the animation graph.

I reread what you asked and realise that my answer is not what you want.Have you tried creating a walk path? Figure > Create Walk Path. I think Geep has a tutorial on it.

If I'm not mistaken, I believe someone - Ockham(?) - made a Python script for that.  Seems I used it for a project I had once a year or so ago.  Damned if I can find it though.

At least I THINK It was Ockham.
