https://developer.nvidia.com/nvidia-flex-110-releasedIn Flex 1.1 we have introduced a new “moving frame” API that allows simulating Flex particles in the local space of an attached accelerating rigid frame, e.g.: a character’s root bone transform. The inertial forces from this frame's movement can then be added in a controlled fashion that limits the effect of non-physical movements. See the NvFlexExtMovingFrame API for details.
интересные новости... насколько я понял можно частицы к костям крепить можно теперь... надо будет потестить.
