You can export walk cycles for use in Walk Designer, as long as you've got the body part names right. To create it in the first place, make a 30-frame walk animation and save it into the Pose library in the Walk Designer folder. That saved file can then be used by anybody, as long as it goes into the same folder in their copy of Poser and as long as they point Walk Designer at the right model (preferably one saved with IK off and -a tip Little_Dragon gave- the morphs and textures stripped out). I get the feeling ERC settings wouldn't work if you made a walk cycle that way, Poser doesn't cope well with ERC settings in poses saved directly with Poser itself. I'll have to try playing with it, there's probably a workaround. Was that what you meant by 'export'?
