Hello !

I am using jPCT to render stellar systems, but I have a problem : some objects disappear...
Here are 2 screenshots :

The system contains 2 planets, a sun and an asteroid belt :


And with a translation along Y axis (bottom of the screen), some asteroids disappear :


I guess I have to change a parameter, but I haven't found which one...
Any ideas ?

BTW, congrats for the software renderer, very powerful and useful
