Hi all,

please consider the following case:
I want to store a terrain as a geometry node 
(Positions and Normals as VBOs).
Now I want to change small parts 
inside the Positions and Normals arrays only..

What change policy for VBOs is actually used?
With the "changed" marking of arrays, 
would it make sense to subdivide the terrain (in a cluster)?
Is it possible to change arrays without getting entries 
into the change list?

Any comments are well appreciated!

Cheers,
Christoph
