Im building an obstacle environment for flying a drone. I surround my area with walls and put objects inside. The problem is that the walls in the back and the ground plane appear in front of the objects when looking through a camera.

I didnt have the problem with gazebo 5.1 so the problem just appeared after updating. Im using ros jade so I have to stick with gazebo 5.x.

I tried different orders, checked to sdk files of the models and everything seems to be normal. It is probably some rendering problem. The shadows of the objects are casted on the ground plane and the walls but the objects itself appear behind it when looking through a camera. I also tried different cameras (openNI kinect and general camera sensor). In the image you can see a wooden box and the wall in the back appears in front of the wooden block.

I hope the next update fixes this. Or is there a known way to solve this problem? Im surprised no one else has this problem with the latest 5.x update.
