Thanx :-),

Imho mesh2 should work, I'm not that pov expert. The algorithm is quite 
easy:
- calculate direction from current position, this can be manipulated by 
different weight factors
- find nearest intersection to the given object instance, this is done 
using 'trace', so it should work with mesh2
   (but this can heavily increase parsing time, I've implemented a 
little macro which searches in all directions, so 96 traces for every 
twig step can result in horrible parsing times if objects are too 
complex, I thought about saving this to a file, so re-reandering with 
the same params will go much faster)
- the resulting end position is than moved to this intersection 
position, leaving a little distance into normal direction of the 
intersection
