2d sprite clipping/culling

[sidshekar]

Hi, I am using 2dtoolkit to make a 2d game and sometimes objects go behind other objects even if they are placed in front of the other objects. To explain it better I have a link of the youtube vid below. Around the 35 second mark you can see the trees go behind the green hills. The tree's z value is 6.5 where as the hills in 6 and still at certain point the trees goes back and forth. I dont understand why this is happening. How to resolve this? Thx.

Are you using a perspective camera? If so, you need to set transparencySortMode to Orthographic at startup.
