title: Unity procedural TileMap generation without creating gameobject per tile
body: <p>I've been searching all over the internet to find a efficient way to create procedural tilemap without creating a gameobject per each tile. There is none, or simply i couldn't find it, because i really don't know how to make a search for it. All the TileMap tutorials i found are creating tiles by creating hunderds of gameobjects. Thus the hierarchy in Unity is expanding uncontrollably.</p>
  
  <p>I'm pretty sure this is not the "right" way to do it. Especially after seeing the new Unity 2D tools that supports tilemaps. Unity made it so, you can create tiles in "one" gameobject, not for each tile.</p>
  
  <p>How to do it in the right way?</p>
