I got Poser5 and Poser7.

I have created one Walk cycle for 25 Frame from Frame 1 to Frame 25.

I want to create loop.  The complete Animation will be for 150 Frame, How to loop this animation. The loop should run 6 times and after a new animation will start from Frame 151 to Frame 251.

2nd Problem I have one more character and I want to use the same loop for this character.
On 2nd character the same loop will start from Frame 10 to Farme 60. ( 2 times )

Can any one please guide how to do this.

you can save an animated pose.  It'll ask you how many frames you want to save.

At frame 26, you would apply the animated pose, etc.

the animated pose is easiest . You can copy and paste keyframes in the keyframe editor.

Ockham had a script called Repeater . at www.ockhamsbungalow.com/python

Thanks for reply. I have gone thru the tutorials and found that saving pose is the eastiest thing in Poser. You create some animation and Select Pose, Click on + and you will be prompted to save. It saves immediately and you can goto any Frame No and can call that pose. 

Thanks for support.
