Hi Martin,

For PagedLOD nodes the children should always be ordered from lowest
resolution/ furthest distance first, to highest resolution/near
distance last.   What you describe fits this just fine.

The TerraPage plugin has extra scheme above PagedLOD that seek to hold
back use of higher resolution children when a neighbouring tile is of
too low a resolution for the boundary meshes to be able to fit
together.  This scheme is pretty complicated and is very specific to
the way that TerraPage maintains central and boundary meshes.  I
haven't personally seen the cycling you talk about but my guess is
that this is the most fruitful area to look at when searching for a
cause.

Robert.
