A static model is a precise, but rigid 3D shape. Animating or making changes to static models is time consuming and tedious.
Smart assets have features (sliders, menus, etc.) for quick and specific adjustments. The level of customization is limitless for the author to decide what can be controlled.
Smart assets are not restricted to just geometry: you can find effects, tools, shaders, environments and much more.
You can also load various smart assets into other DCC apps!
