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 -Brad
