My Team got an assignment to make a realistic eagle where we wanted to use some polygon based system for the dynamic feathers and the static feathers so we tried lot of plugins n stuff but found it pretty heavy so i got an idea to develop the existing hair system to produce good and optimized output then i made this feather system which has both dynamic feathers which uses the dynamic engine as well as static feathers which doesnt use the dynamic engine at all.
