Humm, while I'm thinking about it one other area of parallel developement to look into with Hybrid/Dynamic clothing is Displacement mapping. I remember a while back some one using displacement mapping to create really fabulous detail in a rather plan mesh figure. This might be another route to adding some really complex details in the Dynamic clothing and Dynamic groups of Hybrid.

Also, I generally try to add some wrinkles and folds to add some realism to clothing, but the idea of making a plain flat model and adding several displacement maps to provide the user with a CHOICE of wrinkle/fold patterns is something I've been thinking about, lately. Oh, so many avenues to expore and so little time!

have fun
