title: Create planet with Terrain in Unity
body: <p>I'm looking to create some procedurally-generated planets in unity.  I'm not looking to make huge, realistic planets, but very small, walkable ones (like Super Mario Galaxy).</p>
  
  <p>I've run into a problem though - Terrain objects cannot be rotated, so I can't really make a sphere out of 6 separate squares.  </p>
  
  <p>I've tried importing a hi-res icosphere with limited success.  It's difficult to make look good (even with a high number of faces) when up close.   There's also limited support on terrain-like features on non-terrain objects - like how to blend textures, add grass, or place objects on the surface.</p>
  
  <p>I have seen a few unity store assets that do exactly what I'm requesting, so I know something like this is possible.   I just can't figure out where to start.  I've searched for nearly anything related to the topic and found nothing. </p>
  
  <p>Thank you!</p>
