That cloth sim video to me looks to be too stiff. Specifically @ 2 second mark, when the character moves it’s arms to behind it’s back, the cloth should drop down against the arms.
The sleeves should drop down against the outside of the arms, not be floating out away from the arms. IDK maybe this is just a setting that needs to be tweaked.
@ about 18 seconds the one hand brushes up against the dress/skirt and that really looks pretty good.
Overall, it does look better than anything that blender’s cloth sim can do. I have been watching your work on your TAngra posts and I have to say I am really impressed with your work!
