Hi Robert,
Niclas Olofsson's ForestWorld was using something similar to this to
increase rendering efficiency by breaking his world into square segments. I
had thought his world was infinite, but he told me some time ago that it
wasn't. One of the results of his way of world-building was that it opened
the possibility of making an infinite world quite easily.
Niclas is really the person to speak about this though. I don't know if he
still monitors this list... I know he is very busy these days.
I was going to spend some time adapting my island world to his ForestWorld
but I have been quite busy with work lately myself, and the last couple of
times I looked for ForestWorld it hasn't been up on the net.
I don't see that VNet would have problems with breaking a world into cubic
segments though -- it seems like just an extension of what Niclas was
doing. I think it is a great idea.
Does your Sector System unload a cube immediately you leave it? or always
keep the cube you are in, plus the 6 surrounding it loaded?... or would
that be 14 cubes surrounding it (including diagonally touching cubes as
well as face-touching cubes)? If you unload a cube immediately you leave
it, you could have the unsettling experience of stepping backward over a
cube border and seeing everything vanish from view.
Is it possible to use smaller segments, say 10meter cubes? And adjust the
trigger distance for loading segments?
Best wishes,
- Miriam

I doubt, therefore I might be.
