Iclone currently uses the Nvidia cloth system but the features are barely implemented. I have seen full, totally interactive implementations of Nvidia cloth where the user can actually real time interact with cloth simulations (and this works for hair also,) grabing cloth or hair with a mouse click and moving it wherever they wish. Plus, of course, Nvidia Hair is not even implemented in Iclone at this time. Hopefully both of these can be fully implemented in the next release of Iclone.
