Bad clipping problem

Hi there,
I have a problem of bad clipping in the game I’m making. Some object will clip too soon when I’m too near with the camera. Strangely enough, changing the near clip plane of the camera has no effect. Here is the pic of what’s happening:

How can I avoid this?

Er… no one?

Could you show a small reproducible example? I tried to get objects to behave strange in this way yesterday for a bit. but had no luck in getting something changing near clip had no effect on.
