1: Expand timeline let simulation run for 500 frames
2: Add transparent lambert to the parts of the upper legs that are poking through the dress
3: Select vertexes of the top part of the dress and the waist of the character and nconstraint them together using component to component constraint
I managed to get the dress to stay on the character and not fall off to the ground by using nconstraint component to component, furthermore the geo of the character was made into a passive collider.
nCloth simulation is very unpredictible and there are many issues, nCloth simulation is needed for 15 unique shots and have to be redone each time. Since the movement of the character is different in every shot the simulation is unpredictably in every shot since the same settings will not work on different shots. This makes nCloth not reliable for this project
