It appears that ON_DEMAND rendering is broken in osgTerrain as of rev 11307.
The offend lines appear to be the manual setting of
numchildrenrequiringupdatetraversal in the constructors for
osgTerrain::Terrain.

 

We are using osgEarth (using osgTerrain) and would really like to use
ON_DEMAND to greatly reduce our cpu/gpu footprint.

 

Obviously this change was introduced to fix something (boundary
equalization?).  Is there another option?

 

Thanks
