Encountering a Problem with scene rendering / camera options in bge

Hey Everybody,

we are actually working on a simulation in the bge
and encountering a very strange problem.

When the simulation is running, and we are moving
the camera nearer to our simulation object, the nearer
we get, the more parts of our object dissappear.
It seems like the object is hitting the near clipping plane
of the camera and is so no longer rendered.

I attached 2 pictures, where you can see the full arm,
catching the red ball, and a second, where the camera is closer,
and the arm is cutted and doesnt reach the ball anymore.

I tried to fix the camera near clipping plane to 1mm,
and started the simulation again -> same problem.

Any suggestions what this can be?

Thanks a lot and best Whishes
