Quote - Unfortunately I still do not know how to make dynamic back side of sofa.

It seems sort of like a weird idea, but I've wished for a long time that the direction of gravity for Poser's dynamics was a variable input.  That would solve many problems, simplify many complex clothing simulations, and allow new things like animating a deflating basketball using dynamics.

Sadly it's a feature I strongly doubt we'll ever see.  :sad:

As it is, I think you'd have to animate the back of the couch separately, with everything involved in the sim rotated 90 degrees backwards to allow for the proper direction of gravity.  Then you could presumably use your current (and brilliant!) technique from the mattress.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
