I am using ref_ptrs on the rendering part. However, my backend is not.

HI Bruno,

Make sure you are using ref_ptr<> in your ReadFileCallback for any
scene graph data structures so if you remove nodes from the main scene
graph they don't get deleted mid load.  If you do this properly then
there should be no need to mess around with blocks that would
complicate the code.

Robert.

[osg-users] Wait for Database pager to complete

[Bruno Oliveira]

Hello,

i have a PagedLOD bases scene.

At some point I remove a node, but OSG sometimes is reading a subnode and
crashes at ReadFileCallback.

I can solve this if there is some mechanism to wait for the current
callback to finish reading, like for instance a
osgDB::DataBasePager::waitForCurrentThreadToFinish() function.

Is there something like this?
