Batching static GameObjects

Static batching is a draw call batching method that combines meshes that don’t move to reduce draw calls. It transforms the combined meshes into world space and builds one shared vertex and index buffer for them. Then Unity performs a single draw call that uses this combined meshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info

can significantly reduce the number of draw calls.
