The mask model is done. I will share the screen here. There are 34 chain collections that can be baked with soft body simulation that should (in theory) allow this model to act in physics according to the movement of the mask itself. So if anyone puts this mask on a model that will be moving or moving the head... the gold chains should react to the movement. I don't think I will give it a try anytime soon, as I made this more like a static prop. But it's better to have the option.
I will certainly put this on some girls soon, to have a nice test as a static prop for now. I hope to improve the model and share it at some point. Who is interested?
