I got a very iritating error in Irrlicht.
If the position vector of a node is not in the render-screen, the node isnt drawn. For example a terrain node, which coordinates are 0/0/0.
If the point 0/0/0 is not in the screen, the terrain node isnt shown at all and it flickers.
here is a picture.

Its also happen at other nodes, hope anyone can help me ._.
