Okay, next Q in the 'what is possible with dynamic clothing?' line (I swear I'm going to indebted to make freebies forever for all this help =P).

Can dynamic fabric items be told hold an edge, be it partially or fully?

(warning, bad sketches and crude handwriting await)

the one on the tight I imagine I could do by making the top stiff and the sides more flowing, but the left I can't really think of a way to do besides maybe a displacement map.

My main reason for asking is for a situation like as follows:

A garment had a leather element sewn on top of it's fabric element. While the leather is semi-flexible, I'd want the edges of the leather shape to stay nice and 90 degrees.

Granted, there's a point where I'm just wildly over thinking things and it becomes 'if your going to need that much, make it conforming already!' I'm just trying to scope out what's possible and what's not. My thought-boat likes to go really fast and occassionally needs a 3rd party jetty to ram into, so to speak.
