I have same problem

Hi there,

This is common problem called tunneling, you can read about it online. It is inherent to all physics engines: time is discretized into small chunks, so if something small moves too much between one frame and the next, it can simply "teleport" across a thin wall without ever colliding with it. Obi uses continuous collision detection (CCD) to alleviate this a bit. However it is impossible to completely prevent it under all circumstances.

Common workarounds include limiting the user's movement speed or decreasing the physics timestep (so that time "chunks" are smaller).
