If the
getNumChildrenRequiringUpdateTraversal()
for node returns 0 and the node has no callbacks, OSG will skip it during update traversal.As a result, for our RigGeometry objects skeletons will not be initialized properly.
To avoid this issue, we add an empty callback to every RigGeometry object to force OSG to process it during update traversal.
A better way to do it is to use the
setNumChildrenRequiringUpdateTraversal()
function, which is widely used in OSG examples for the same purpose.
