creating footsteaps.

to create footsteps you need to Click the Motion tab. Activate the Footstep Mode button. In the Footstep Creation rollout, click the Create Multiple Footsteps button. The Create Multiple Footsteps: Walk dialog appears. Set the Number of Footsteps to 12 and hit OK. This will create an animation that is 183 frames in length.From the Footstep Operations rollout menu, click the Create Keys for Inactive Footsteps button. This tells the biped to use the footsteps you just created. Play the animation. The biped walks along the footsteps

the problems i found with this was that the tail kept sinking into the floor, so i then had to re animate the tail to move when walking.
