ok new tip for clothing.

how to do dynamic simulation with clothes that has hard folds? folds that dont change when the cloth moves?

lets say that you model the fold on the jacket. when you simulate they will be gone because the cloth moved. how to have the flods on the cloth?

morphs. its simple morphs.
-you model a jacket ,pants or shirt. you import that model into blender,zbrush,.....
-you add folds the way you want.
-in poser you run the simulation with the model without folds.
-you add the second model with folds

voila. now you have cloth with folds that dont change with the simulation. it makes your cloth more realistic and more interesting.
