heyas; for something like that, i'd try to use rhino, which outputs flat square maps automatically. (plus it has a drape command ;) ) you can also try morphing and/or posing the sucker in poser until it is laid out the way you want it, then export the obj. you can then shoot the uvs, save the uvs file and (if poser didn't do the 'incompatible facet structure' deal it's always doing to me) import them onto the base model. in other words, spread the blanket out in poser, then do a planar map of the rectangle, and import those uvs onto the draped blanket.
