title: SpriteRenderers not getting batched
body: <p>I have a game with like 100 draw calls. But all i have on scene is my background(which is made from 100 gameobjects with spriterenderer and collider). I don't get why those are not batched. I use the same settings for them all. All I change is sprite, othervise totaly the same objects.</p>
  
  <p>Any idea what i'm doing wrong? </p>
