Remarks

A StaticMesh is a piece of geometry that consists of a static set of polygons. Static Meshes can be translated, rotated, and scaled, but they cannot have their vertices animated in any way. As such, they are more efficient to render than other types of geometry such as USkeletalMesh, and they are often the basic building block of levels created in the engine.
