title: How to bake static Unit scene into one big mesh and texture
body: <p>I have a big complex unity scene including terrain, trees, grass, flowers and many other objects.</p>
  
  <p>I'm having performance problems and i was wondering if its possible to bake all static objects that never move or change like terrain trees, houses, and other props etc, into one big static object to increase performance?</p>
  
  <p>Thanks</p>
