Hi Gareee! I love you grinning avatar and your memory is astounding. Thanks.
I am not sure how dynamic cloths work but is there a way for someone to create this or various versions as a dynamic and export or save it out as a preset .obj or pp2 file so I can open it in Poser 4?
I know someone created an old fashioned birthing chair for me that had a modesty cloth and I think it too was dynamic but opened in Poser 4 was nicely shaped to fit over the delivering womans splayed knees. It just worked. Si I am hoping someone else can easily create this sheet this way.

I have used the ripple plane in Poser 4 (looks lie a ruffled square chip or corrugated sheet metal the same way placing it on a bed surface, coloring and texturing like the bed surface and lowering it so the tops of the ripples show. It works for renders. Now I need something more Fabric and wrinkled like.
