[SOLVED] Occlusion Culling problem

When I use Occlusion Culling and I get close to objects, almost everything disappears.

After Occlusion:

[17687-2013-11-09+10_31_52-2013-11-09+08_20_11-unity±+mainscene.unity±+finalfps±+pc,+mac+&+linux+standal.jpg|17687]

Before Occlusion:

[17688-2013-11-09+10_34_17-2013-11-09+08_19_58-unity±+mainscene.unity±+finalfps±+pc,+mac+&+linux+standal.jpg|17688]

SOLVED - The cell size was too small. I shrunk it to 3 instead of 1 and works perfectly!

May be your taget object attachment is wrong. see the inspector view attached objects.
