TileMap Depth problem

Hello, I have a problem with the experimental tilemap concerning depth :

Please look at movie :

Someone can help me ?
I don’t understand why when my camera is on Z=0 the tilemap disappears ?

I can’t wait for tilemap release ! it’s really good job !

The problem come from the settings of camera :

Clipping planes needs to have big values :
Near : -100000000000000
Far : 100000000000000

Now it works… but I think that’s not the good solution…
if someone have other ? I take !
